We look at the division of 91761448 by 631 
We want to figure out the number of times 91761448 can be divided by 631.

Step 1:
631 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 631

Advancing to step 2:
The number 631 fits into 91 0 times, leaving a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 631

Advancing to step 3:
631 goes into 917 1 times with a remainder of 286.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 631 from 917 leaves us with 286.
Bring next digit (6) of the dividend behind the 286 and repeat the process: 2866 / 631

Step 4:
2866 divided by 631 is 4 with a remainder of 342.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 2524 from 2866 and we're left with 342.
Take the next digit (1) from the dividend and append it to 342, then repeat: 3421 / 631

Step 5:
631 can be fit into 3421 5 times, resulting in a remainder of 266.
Use 5 as the next digit of our solution. 
Result so far: 145.0
Deduct 3155 from 3421 and we're left with 266.
Append the next digit (4) from the dividend to 266 and continue with: 2664 / 631

On to step 6:
If we divide 2664 by 631, we get 4 and a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 1454.0
Subtract 2524 from 2664 to get 140.
Take the next digit (4) from the dividend and append it to 140, then repeat: 1404 / 631

Moving on to step 7:
The number 631 fits into 1404 2 times, leaving a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 14542.0
The remainder is 142 after subtracting 1262 from 1404.
Append the next digit (8) from the dividend to 142 and continue with: 1428 / 631

Step 8:
631 goes into 1428 2 times with a remainder of 166.
The number 2 becomes the next digit in our result. 
Result so far: 145422.0
Subtract 1262 from 1428 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Moving on to step 9:
When dividing 1660 by 631, we get 2 with a remainder of 398.
Write down 2 as next digit of the result. 
Result so far: 145422.2
Subtracting 1262 from 1660 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 10:
When dividing 3980 by 631, we get 6 with a remainder of 194.
The number 6 becomes the next digit in our result. 
Result so far: 145422.26
Subtracting 3786 from 3980 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 11:
When dividing 1940 by 631, we get 3 with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 145422.263
If we subtract 1893 from 1940, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
When dividing 470 by 631, we get 0 with a remainder of 470.
Write down 0 as next digit of the result. 
Result so far: 145422.263
If we take 0 away from 470, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 13:
4700 divided by 631 is 7 with a remainder of 283.
Use 7 as the next digit of our solution. 
Result so far: 145422.26307
If we subtract 4417 from 4700, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 14:
The number 631 fits into 2830 4 times, leaving a remainder of 306.
Record the quotient 4 as the next digit in the result. 
Result so far: 145422.263074
Subtract 2524 from 2830 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 15:
When dividing 3060 by 631, we get 4 with a remainder of 536.
Record the quotient 4 as the next digit in the result. 
Result so far: 145422.2630744
Subtracting 2524 from 3060 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

After the division, we end up with 145422.2630744 and a remainder of 5.36e-06.
