77888759 ÷ 915 
We want to figure out the number of times 77888759 can be divided by 915.

Moving on to step 1:
If we divide 7 by 915, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 915

Advancing to step 2:
The number 915 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (8) from the dividend, attach it to 77 and continue: 778 / 915

Going ahead to step 3:
The number 915 fits into 778 0 times, leaving a remainder of 778.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 778, we get 778.
Fetch the next digit (8) from the dividend, attach it to 778 and continue: 7788 / 915

Step 4:
7788 divided by 915 is 8 with a remainder of 468.
The next digit of our result is 8. 
Result so far: 8.0
If we take 7320 away from 7788, we end up with 468.
Append the next digit (8) from the dividend to 468 and continue with: 4688 / 915

Moving on to step 5:
915 can be fit into 4688 5 times, resulting in a remainder of 113.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtracting 4575 from 4688 leaves us with 113.
Take the next digit (7) from the dividend and append it to 113, then repeat: 1137 / 915

Advancing to step 6:
If we divide 1137 by 915, we get 1 and a remainder of 222.
The number 1 becomes the next digit in our result. 
Result so far: 851.0
If we take 915 away from 1137, we end up with 222.
Append the next digit (5) from the dividend to 222 and continue with: 2225 / 915

Advancing to step 7:
When dividing 2225 by 915, we get 2 with a remainder of 395.
The next digit of our result is 2. 
Result so far: 8512.0
Subtracting 1830 from 2225 leaves us with 395.
Bring next digit (9) of the dividend behind the 395 and repeat the process: 3959 / 915

Going ahead to step 8:
915 can be fit into 3959 4 times, resulting in a remainder of 299.
Use 4 as the next digit of our solution. 
Result so far: 85124.0
Subtracting 3660 from 3959 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 9:
When dividing 2990 by 915, we get 3 with a remainder of 245.
Record the quotient 3 as the next digit in the result. 
Result so far: 85124.3
If we take 2745 away from 2990, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 10:
2450 divided by 915 is 2 with a remainder of 620.
The next digit of our result is 2. 
Result so far: 85124.32
If we subtract 1830 from 2450, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Step 11:
6200 divided by 915 is 6 with a remainder of 710.
Write down 6 as next digit of the result. 
Result so far: 85124.326
Deduct 5490 from 6200 and we're left with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Advancing to step 12:
When dividing 7100 by 915, we get 7 with a remainder of 695.
Use 7 as the next digit of our solution. 
Result so far: 85124.3267
Subtracting 6405 from 7100 leaves us with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

Advancing to step 13:
The number 915 fits into 6950 7 times, leaving a remainder of 545.
The number 7 becomes the next digit in our result. 
Result so far: 85124.32677
Deduct 6405 from 6950 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

The quotient of the division is 85124.32677, and the remainder is 0.000545.
