Let's divide 91771975 by 748
We want to figure out the number of times 91771975 can be divided by 748.

On to step 1:
748 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 748

Moving on to step 2:
748 can be fit into 91 0 times, resulting in a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 748

Step 3:
917 divided by 748 is 1 with a remainder of 169.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 748 from 917 leaves us with 169.
Take the next digit (7) from the dividend and append it to 169, then repeat: 1697 / 748

Step 4:
When dividing 1697 by 748, we get 2 with a remainder of 201.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 1496 from 1697 and we're left with 201.
Include the next digit (1) from the dividend after 201, then repeat: 2011 / 748

On to step 5:
748 goes into 2011 2 times with a remainder of 515.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
If we take 1496 away from 2011, we end up with 515.
Include the next digit (9) from the dividend after 515, then repeat: 5159 / 748

Let's proceed to step 6:
5159 divided by 748 is 6 with a remainder of 671.
Use 6 as the next digit of our solution. 
Result so far: 1226.0
Subtracting 4488 from 5159 leaves us with 671.
Fetch the next digit (7) from the dividend, attach it to 671 and continue: 6717 / 748

Let's proceed to step 7:
The number 748 fits into 6717 8 times, leaving a remainder of 733.
Record the quotient 8 as the next digit in the result. 
Result so far: 12268.0
If we take 5984 away from 6717, we end up with 733.
Bring next digit (5) of the dividend behind the 733 and repeat the process: 7335 / 748

Advancing to step 8:
7335 divided by 748 is 9 with a remainder of 603.
The number 9 becomes the next digit in our result. 
Result so far: 122689.0
If we subtract 6732 from 7335, we get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Advancing to step 9:
748 can be fit into 6030 8 times, resulting in a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 122689.8
Subtract 5984 from 6030 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
The number 748 fits into 460 0 times, leaving a remainder of 460.
Record the quotient 0 as the next digit in the result. 
Result so far: 122689.8
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 11:
748 goes into 4600 6 times with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 122689.806
Subtracting 4488 from 4600 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
748 goes into 1120 1 times with a remainder of 372.
Use 1 as the next digit of our solution. 
Result so far: 122689.8061
If we take 748 away from 1120, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 13:
When dividing 3720 by 748, we get 4 with a remainder of 728.
Write down 4 as next digit of the result. 
Result so far: 122689.80614
Subtract 2992 from 3720 to get 728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Step 14:
The number 748 fits into 7280 9 times, leaving a remainder of 548.
The next digit of our result is 9. 
Result so far: 122689.806149
Subtracting 6732 from 7280 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 15:
748 can be fit into 5480 7 times, resulting in a remainder of 244.
The number 7 becomes the next digit in our result. 
Result so far: 122689.8061497
Subtract 5236 from 5480 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 16:
748 goes into 2440 3 times with a remainder of 196.
Use 3 as the next digit of our solution. 
Result so far: 122689.80614973
Subtracting 2244 from 2440 leaves us with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 122689.80614973, with a leftover of 1.96e-07.
