Let's divide 97941270 by 689
We want to divide 97941270 by 689.

On to step 1:
689 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 689

Moving on to step 2:
If we divide 97 by 689, we get 0 and a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 97 after subtracting 0 from 97.
Take the next digit (9) from the dividend and append it to 97, then repeat: 979 / 689

Moving on to step 3:
979 divided by 689 is 1 with a remainder of 290.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 689 from 979, we get 290.
Bring next digit (4) of the dividend behind the 290 and repeat the process: 2904 / 689

Going ahead to step 4:
When dividing 2904 by 689, we get 4 with a remainder of 148.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 148 after subtracting 2756 from 2904.
Append the next digit (1) from the dividend to 148 and continue with: 1481 / 689

Advancing to step 5:
The number 689 fits into 1481 2 times, leaving a remainder of 103.
Write down 2 as next digit of the result. 
Result so far: 142.0
Deduct 1378 from 1481 and we're left with 103.
Bring next digit (2) of the dividend behind the 103 and repeat the process: 1032 / 689

Let's proceed to step 6:
When dividing 1032 by 689, we get 1 with a remainder of 343.
Write down 1 as next digit of the result. 
Result so far: 1421.0
If we subtract 689 from 1032, we get 343.
Fetch the next digit (7) from the dividend, attach it to 343 and continue: 3437 / 689

Moving on to step 7:
The number 689 fits into 3437 4 times, leaving a remainder of 681.
The number 4 becomes the next digit in our result. 
Result so far: 14214.0
The remainder is 681 after subtracting 2756 from 3437.
Append the next digit (0) from the dividend to 681 and continue with: 6810 / 689

Going ahead to step 8:
When dividing 6810 by 689, we get 9 with a remainder of 609.
The number 9 becomes the next digit in our result. 
Result so far: 142149.0
Subtracting 6201 from 6810 leaves us with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Going ahead to step 9:
6090 divided by 689 is 8 with a remainder of 578.
Write down 8 as next digit of the result. 
Result so far: 142149.8
Subtract 5512 from 6090 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Going ahead to step 10:
689 goes into 5780 8 times with a remainder of 268.
The next digit of our result is 8. 
Result so far: 142149.88
The remainder is 268 after subtracting 5512 from 5780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final result is 142149.88 with a remainder of 0.268.
