We divide 77728866 by 715
We want to figure out the number of times 77728866 can be divided by 715.

Step 1:
7 divided by 715 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 715

Moving on to step 2:
If we divide 77 by 715, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 715

Moving on to step 3:
If we divide 777 by 715, we get 1 and a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 715 away from 777, we end up with 62.
Take the next digit (2) from the dividend and append it to 62, then repeat: 622 / 715

Going ahead to step 4:
715 goes into 622 0 times with a remainder of 622.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 622 and we're left with 622.
Take the next digit (8) from the dividend and append it to 622, then repeat: 6228 / 715

Going ahead to step 5:
6228 divided by 715 is 8 with a remainder of 508.
The next digit of our result is 8. 
Result so far: 108.0
If we take 5720 away from 6228, we end up with 508.
Append the next digit (8) from the dividend to 508 and continue with: 5088 / 715

Advancing to step 6:
When dividing 5088 by 715, we get 7 with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 1087.0
Deduct 5005 from 5088 and we're left with 83.
Take the next digit (6) from the dividend and append it to 83, then repeat: 836 / 715

Let's proceed to step 7:
836 divided by 715 is 1 with a remainder of 121.
Record the quotient 1 as the next digit in the result. 
Result so far: 10871.0
If we subtract 715 from 836, we get 121.
Append the next digit (6) from the dividend to 121 and continue with: 1216 / 715

On to step 8:
When dividing 1216 by 715, we get 1 with a remainder of 501.
Write down 1 as next digit of the result. 
Result so far: 108711.0
If we take 715 away from 1216, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 9:
715 can be fit into 5010 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 108711.7
The remainder is 5 after subtracting 5005 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
715 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 108711.7
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
715 can be fit into 500 0 times, resulting in a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 108711.7
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 108711.7, with a leftover of 0.05.
