We look at the division of 86901944 by 631 
Let's see how many times 631 fits into 86901944.

Going ahead to step 1:
If we divide 8 by 631, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 631

Let's proceed to step 2:
631 can be fit into 86 0 times, resulting in a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 631

Moving on to step 3:
The number 631 fits into 869 1 times, leaving a remainder of 238.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 631 from 869 leaves us with 238.
Append the next digit (0) from the dividend to 238 and continue with: 2380 / 631

Moving on to step 4:
The number 631 fits into 2380 3 times, leaving a remainder of 487.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1893 from 2380 to get 487.
Take the next digit (1) from the dividend and append it to 487, then repeat: 4871 / 631

Let's proceed to step 5:
If we divide 4871 by 631, we get 7 and a remainder of 454.
The next digit of our result is 7. 
Result so far: 137.0
Subtracting 4417 from 4871 leaves us with 454.
Grab the next digit (9) from the dividend, add it to 454, then carry on: 4549 / 631

On to step 6:
631 can be fit into 4549 7 times, resulting in a remainder of 132.
The next digit of our result is 7. 
Result so far: 1377.0
Deduct 4417 from 4549 and we're left with 132.
Fetch the next digit (4) from the dividend, attach it to 132 and continue: 1324 / 631

Going ahead to step 7:
1324 divided by 631 is 2 with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 13772.0
The remainder is 62 after subtracting 1262 from 1324.
Include the next digit (4) from the dividend after 62, then repeat: 624 / 631

Advancing to step 8:
The number 631 fits into 624 0 times, leaving a remainder of 624.
The next digit of our result is 0. 
Result so far: 137720.0
Deduct 0 from 624 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Advancing to step 9:
If we divide 6240 by 631, we get 9 and a remainder of 561.
Put 9 as the next digit of the answer. 
Result so far: 137720.9
If we subtract 5679 from 6240, we get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Let's proceed to step 10:
5610 divided by 631 is 8 with a remainder of 562.
The next digit of our result is 8. 
Result so far: 137720.98
The remainder is 562 after subtracting 5048 from 5610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Let's proceed to step 11:
The number 631 fits into 5620 8 times, leaving a remainder of 572.
Put 8 as the next digit of the answer. 
Result so far: 137720.988
The remainder is 572 after subtracting 5048 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

The quotient of the division is 137720.988, and the remainder is 0.0572.
