91564918 ÷ 77 
We're looking to find how many times 77 goes into 91564918.

Advancing to step 1:
When dividing 9 by 77, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 77

Let's proceed to step 2:
When dividing 91 by 77, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 77 from 91 to get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 77

Going ahead to step 3:
If we divide 145 by 77, we get 1 and a remainder of 68.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 68 after subtracting 77 from 145.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 77

On to step 4:
The number 77 fits into 686 8 times, leaving a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtracting 616 from 686 leaves us with 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 77

On to step 5:
704 divided by 77 is 9 with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1189.0
The remainder is 11 after subtracting 693 from 704.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 77

Moving on to step 6:
If we divide 119 by 77, we get 1 and a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 11891.0
Subtracting 77 from 119 leaves us with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 77

Advancing to step 7:
If we divide 421 by 77, we get 5 and a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 118915.0
Deduct 385 from 421 and we're left with 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 77

On to step 8:
When dividing 368 by 77, we get 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 1189154.0
Subtract 308 from 368 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
The number 77 fits into 600 7 times, leaving a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 1189154.7
Deduct 539 from 600 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 10:
The number 77 fits into 610 7 times, leaving a remainder of 71.
The next digit of our result is 7. 
Result so far: 1189154.77
If we subtract 539 from 610, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 1189154.77, and the remainder is 0.071.
