Firstly, put the larger number inside the division bar and the smaller number outside.
For example : 93.8
Firstly, put the larger number inside the division bar and the smaller number outside.
9 3 . 8
Firstly, put the larger number inside the division bar and the smaller number outside.
For example : 93.8
Firstly, put the larger number inside the division bar and the smaller number outside.
9 3 . 8 7
For example : 93.8 divided by 7
Before you go any further you should put a decimal point above the division bar, directly above the decimal point below the division bar
9 3 . 8 7
Before you go any further you should put a decimal point above the division bar, directly above the decimal point below the division bar
9 3 . 8 7 .
You can then complete the division sum as if you were using whole numbers.
9 3 . 8 7 .
Firstly, try to divide the number in the tens column (9) by 7
9 3 . 8 7 .
Firstly, try to divide the number in the tens column (9) by 79 divided by 7 = 1 remainder 2
9 3 . 8 7 .
Firstly, try to divide the number in the tens column (9) by 79 divided by 7 = 1 remainder 2 The 1 is placed directly above the 9
9 3 . 8 7 .
Firstly, try to divide the number in the tens column (9) by 79 divided by 7 = 1 remainder 2 The 1 is placed directly above the 9
9 3 . 8 7 1 .
Firstly, try to divide the number in the tens column (9) by 79 divided by 7 = 1 remainder 2 And the remainder (2) is placed next to the 3 in the units
9 3 . 8 7 1 .
Firstly, try to divide the number in the tens column (9) by 79 divided by 7 = 1 remainder 2 And the remainder (2) is placed next to the 3 in the units
9 3 . 8 7 1 .
2
Now, divide the new number in the units column (23) by 7
9 3 . 8 7 1 .
2
Now, divide the new number in the units column (23) by 723 divided by 7 = 3 remainder 2
9 3 . 8 7 1 .
2
Now, divide the new number in the units column (23) by 723 divided by 7 = 3 remainder 2The 3 is placed directly above the 23 in the units column
9 3 . 8 7 1 .
2
Now, divide the new number in the units column (23) by 723 divided by 7 = 3 remainder 2The 3 is placed directly above the 23 in the units column
9 3 . 8 7 1 3 .
2
Now, divide the new number in the units column (23) by 723 divided by 7 = 3 remainder 2And the remainder of 2 is placed next to the 8 in the tenths
9 3 . 8 7 1 3 .
2
Now, divide the new number in the units column (23) by 723 divided by 7 = 3 remainder 2And the remainder of 2 is placed next to the 8 in the tenths
9 3 . 8 7 1 3 .
2 2
Finally, divide the new number in the tenths column (28) by 7
9 3 . 8 7 1 3 .
2 2
Finally, divide the new number in the tenths column (28) by 728 divided by 7 = 4
9 3 . 8 7 1 3 .
2 2
Finally, divide the new number in the tenths column (28) by 728 divided by 7 = 4The 4 is placed above the 28 in the tenths column
9 3 . 8 7 1 3 .
2 2
Finally, divide the new number in the tenths column (28) by 728 divided by 7 = 4The 4 is placed above the 28 in the tenths column
9 3 . 8 7 1 3 . 4
2 2
To give the final answer; 93.8 divided by 7 = 13.4
9 3 . 8 7 1 3 . 4
2 2
That’s it for now......
