We look at the division of 10399236 by 631 
Our goal is to divide 10399236 by 631.

Going ahead to step 1:
1 divided by 631 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 631

Moving on to step 2:
631 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 631

Moving on to step 3:
The number 631 fits into 103 0 times, leaving a remainder of 103.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 103 after subtracting 0 from 103.
Bring next digit (9) of the dividend behind the 103 and repeat the process: 1039 / 631

On to step 4:
The number 631 fits into 1039 1 times, leaving a remainder of 408.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 631 from 1039 and we're left with 408.
Bring next digit (9) of the dividend behind the 408 and repeat the process: 4089 / 631

Going ahead to step 5:
631 goes into 4089 6 times with a remainder of 303.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 303 after subtracting 3786 from 4089.
Fetch the next digit (2) from the dividend, attach it to 303 and continue: 3032 / 631

Advancing to step 6:
The number 631 fits into 3032 4 times, leaving a remainder of 508.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
If we subtract 2524 from 3032, we get 508.
Grab the next digit (3) from the dividend, add it to 508, then carry on: 5083 / 631

Going ahead to step 7:
5083 divided by 631 is 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 1648.0
Subtract 5048 from 5083 to get 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 631

On to step 8:
631 can be fit into 356 0 times, resulting in a remainder of 356.
Record the quotient 0 as the next digit in the result. 
Result so far: 16480.0
If we subtract 0 from 356, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 9:
If we divide 3560 by 631, we get 5 and a remainder of 405.
The next digit of our result is 5. 
Result so far: 16480.5
Subtract 3155 from 3560 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 10:
631 can be fit into 4050 6 times, resulting in a remainder of 264.
Write down 6 as next digit of the result. 
Result so far: 16480.56
If we take 3786 away from 4050, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 11:
631 goes into 2640 4 times with a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 16480.564
The remainder is 116 after subtracting 2524 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 12:
631 can be fit into 1160 1 times, resulting in a remainder of 529.
Use 1 as the next digit of our solution. 
Result so far: 16480.5641
The remainder is 529 after subtracting 631 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

On to step 13:
631 goes into 5290 8 times with a remainder of 242.
Put 8 as the next digit of the answer. 
Result so far: 16480.56418
Deduct 5048 from 5290 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 14:
If we divide 2420 by 631, we get 3 and a remainder of 527.
Put 3 as the next digit of the answer. 
Result so far: 16480.564183
If we take 1893 away from 2420, we end up with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

On to step 15:
5270 divided by 631 is 8 with a remainder of 222.
Use 8 as the next digit of our solution. 
Result so far: 16480.5641838
If we subtract 5048 from 5270, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 16:
The number 631 fits into 2220 3 times, leaving a remainder of 327.
The number 3 becomes the next digit in our result. 
Result so far: 16480.56418383
If we take 1893 away from 2220, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Our division results in 16480.56418383 with a remaining 3.27e-07.
