Let's divide 78718991 by 754
We want to divide 78718991 by 754.

Step 1:
The number 754 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 754

Moving on to step 2:
78 divided by 754 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 754

Let's proceed to step 3:
The number 754 fits into 787 1 times, leaving a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 754 from 787 and we're left with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 754

Step 4:
754 goes into 331 0 times with a remainder of 331.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 331 leaves us with 331.
Take the next digit (8) from the dividend and append it to 331, then repeat: 3318 / 754

Step 5:
3318 divided by 754 is 4 with a remainder of 302.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtract 3016 from 3318 to get 302.
Grab the next digit (9) from the dividend, add it to 302, then carry on: 3029 / 754

Advancing to step 6:
754 can be fit into 3029 4 times, resulting in a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 1044.0
Subtracting 3016 from 3029 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 754

On to step 7:
754 goes into 139 0 times with a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 10440.0
Deduct 0 from 139 and we're left with 139.
Bring next digit (1) of the dividend behind the 139 and repeat the process: 1391 / 754

Let's proceed to step 8:
If we divide 1391 by 754, we get 1 and a remainder of 637.
The next digit of our result is 1. 
Result so far: 104401.0
Subtract 754 from 1391 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Let's proceed to step 9:
If we divide 6370 by 754, we get 8 and a remainder of 338.
The number 8 becomes the next digit in our result. 
Result so far: 104401.8
If we subtract 6032 from 6370, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Going ahead to step 10:
754 goes into 3380 4 times with a remainder of 364.
Write down 4 as next digit of the result. 
Result so far: 104401.84
Deduct 3016 from 3380 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 11:
When dividing 3640 by 754, we get 4 with a remainder of 624.
The number 4 becomes the next digit in our result. 
Result so far: 104401.844
If we subtract 3016 from 3640, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

The quotient of the division is 104401.844, and the remainder is 0.0624.
