We look at the division of 77715648 by 566 
We're looking to find how many times 566 goes into 77715648.

Step 1:
566 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 566

Let's proceed to step 2:
566 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 566

On to step 3:
566 goes into 777 1 times with a remainder of 211.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 566 from 777 to get 211.
Take the next digit (1) from the dividend and append it to 211, then repeat: 2111 / 566

On to step 4:
If we divide 2111 by 566, we get 3 and a remainder of 413.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 1698 from 2111, we get 413.
Include the next digit (5) from the dividend after 413, then repeat: 4135 / 566

Let's proceed to step 5:
If we divide 4135 by 566, we get 7 and a remainder of 173.
Write down 7 as next digit of the result. 
Result so far: 137.0
Deduct 3962 from 4135 and we're left with 173.
Take the next digit (6) from the dividend and append it to 173, then repeat: 1736 / 566

On to step 6:
When dividing 1736 by 566, we get 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 1373.0
Subtracting 1698 from 1736 leaves us with 38.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 566

Let's proceed to step 7:
The number 566 fits into 384 0 times, leaving a remainder of 384.
Use 0 as the next digit of our solution. 
Result so far: 13730.0
Subtract 0 from 384 to get 384.
Grab the next digit (8) from the dividend, add it to 384, then carry on: 3848 / 566

Let's proceed to step 8:
If we divide 3848 by 566, we get 6 and a remainder of 452.
The next digit of our result is 6. 
Result so far: 137306.0
If we take 3396 away from 3848, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 9:
When dividing 4520 by 566, we get 7 with a remainder of 558.
Put 7 as the next digit of the answer. 
Result so far: 137306.7
If we subtract 3962 from 4520, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Moving on to step 10:
5580 divided by 566 is 9 with a remainder of 486.
Put 9 as the next digit of the answer. 
Result so far: 137306.79
If we subtract 5094 from 5580, we get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 11:
When dividing 4860 by 566, we get 8 with a remainder of 332.
The next digit of our result is 8. 
Result so far: 137306.798
Subtract 4528 from 4860 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 12:
3320 divided by 566 is 5 with a remainder of 490.
Use 5 as the next digit of our solution. 
Result so far: 137306.7985
Subtracting 2830 from 3320 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 13:
4900 divided by 566 is 8 with a remainder of 372.
The next digit of our result is 8. 
Result so far: 137306.79858
Subtracting 4528 from 4900 leaves us 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.

Advancing to step 14:
The number 566 fits into 3720 6 times, leaving a remainder of 324.
Record the quotient 6 as the next digit in the result. 
Result so far: 137306.798586
Subtract 3396 from 3720 to get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 15:
The number 566 fits into 3240 5 times, leaving a remainder of 410.
Record the quotient 5 as the next digit in the result. 
Result so far: 137306.7985865
The remainder is 410 after subtracting 2830 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 16:
4100 divided by 566 is 7 with a remainder of 138.
Record the quotient 7 as the next digit in the result. 
Result so far: 137306.79858657
Deduct 3962 from 4100 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 137306.79858657 with a remainder of 1.38e-07.
