Let's divide 72103521 by 631
We want to figure out the number of times 72103521 can be divided by 631.

Advancing to step 1:
The number 631 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 631

On to step 2:
631 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 631

Let's proceed to step 3:
631 goes into 721 1 times with a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 631 from 721, we get 90.
Append the next digit (0) from the dividend to 90 and continue with: 900 / 631

Going ahead to step 4:
900 divided by 631 is 1 with a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 631 from 900 to get 269.
Take the next digit (3) from the dividend and append it to 269, then repeat: 2693 / 631

Going ahead to step 5:
631 goes into 2693 4 times with a remainder of 169.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we take 2524 away from 2693, we end up with 169.
Append the next digit (5) from the dividend to 169 and continue with: 1695 / 631

Let's proceed to step 6:
When dividing 1695 by 631, we get 2 with a remainder of 433.
Put 2 as the next digit of the answer. 
Result so far: 1142.0
If we subtract 1262 from 1695, we get 433.
Fetch the next digit (2) from the dividend, attach it to 433 and continue: 4332 / 631

Let's proceed to step 7:
When dividing 4332 by 631, we get 6 with a remainder of 546.
Use 6 as the next digit of our solution. 
Result so far: 11426.0
Deduct 3786 from 4332 and we're left with 546.
Bring next digit (1) of the dividend behind the 546 and repeat the process: 5461 / 631

Advancing to step 8:
The number 631 fits into 5461 8 times, leaving a remainder of 413.
Write down 8 as next digit of the result. 
Result so far: 114268.0
If we take 5048 away from 5461, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Let's proceed to step 9:
4130 divided by 631 is 6 with a remainder of 344.
Use 6 as the next digit of our solution. 
Result so far: 114268.6
The remainder is 344 after subtracting 3786 from 4130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 10:
631 can be fit into 3440 5 times, resulting in a remainder of 285.
The next digit of our result is 5. 
Result so far: 114268.65
If we subtract 3155 from 3440, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 11:
When dividing 2850 by 631, we get 4 with a remainder of 326.
The number 4 becomes the next digit in our result. 
Result so far: 114268.654
Subtract 2524 from 2850 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 12:
631 can be fit into 3260 5 times, resulting in a remainder of 105.
The next digit of our result is 5. 
Result so far: 114268.6545
Subtracting 3155 from 3260 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 13:
If we divide 1050 by 631, we get 1 and a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 114268.65451
The remainder is 419 after subtracting 631 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 14:
The number 631 fits into 4190 6 times, leaving a remainder of 404.
The number 6 becomes the next digit in our result. 
Result so far: 114268.654516
Deduct 3786 from 4190 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 15:
631 can be fit into 4040 6 times, resulting in a remainder of 254.
The next digit of our result is 6. 
Result so far: 114268.6545166
The remainder is 254 after subtracting 3786 from 4040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Our division results in 114268.6545166 with a remaining 2.54e-06.
