91190879 divided by 63 
We want to figure out the number of times 91190879 can be divided by 63.

Step 1:
When dividing 9 by 63, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 63

Moving on to step 2:
When dividing 91 by 63, we get 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 63 from 91 and we're left with 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 63

Advancing to step 3:
If we divide 281 by 63, we get 4 and a remainder of 29.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 252 from 281 leaves us with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 63

On to step 4:
When dividing 299 by 63, we get 4 with a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 144.0
Subtracting 252 from 299 leaves us with 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 63

Step 5:
If we divide 470 by 63, we get 7 and a remainder of 29.
The next digit of our result is 7. 
Result so far: 1447.0
If we subtract 441 from 470, we get 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 63

Going ahead to step 6:
The number 63 fits into 298 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 14474.0
Deduct 252 from 298 and we're left with 46.
Grab the next digit (7) from the dividend, add it to 46, then carry on: 467 / 63

Moving on to step 7:
If we divide 467 by 63, we get 7 and a remainder of 26.
The next digit of our result is 7. 
Result so far: 144747.0
Deduct 441 from 467 and we're left with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 63

On to step 8:
63 goes into 269 4 times with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 1447474.0
Deduct 252 from 269 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
The number 63 fits into 170 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 1447474.2
If we subtract 126 from 170, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
When dividing 440 by 63, we get 6 with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 1447474.26
Subtract 378 from 440 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
63 goes into 620 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 1447474.269
Deduct 567 from 620 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 12:
63 goes into 530 8 times with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 1447474.2698
The remainder is 26 after subtracting 504 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
If we divide 260 by 63, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1447474.26984
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 63, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1447474.269841
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 15:
When dividing 170 by 63, we get 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 1447474.2698412
Deduct 126 from 170 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 16:
When dividing 440 by 63, we get 6 with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 1447474.26984126
If we take 378 away from 440, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 1447474.26984126, with a leftover of 6.2e-08.
