We look at the division of 78911216 by 115 
We want to figure out the number of times 78911216 can be divided by 115.

Moving on to step 1:
115 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 115

On to step 2:
If we divide 78 by 115, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 115

Going ahead to step 3:
789 divided by 115 is 6 with a remainder of 99.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 99 after subtracting 690 from 789.
Take the next digit (1) from the dividend and append it to 99, then repeat: 991 / 115

On to step 4:
115 goes into 991 8 times with a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 68.0
The remainder is 71 after subtracting 920 from 991.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 115

On to step 5:
115 can be fit into 711 6 times, resulting in a remainder of 21.
The next digit of our result is 6. 
Result so far: 686.0
Subtract 690 from 711 to get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 115

Step 6:
115 can be fit into 212 1 times, resulting in a remainder of 97.
Write down 1 as next digit of the result. 
Result so far: 6861.0
Subtracting 115 from 212 leaves us with 97.
Append the next digit (1) from the dividend to 97 and continue with: 971 / 115

Let's proceed to step 7:
When dividing 971 by 115, we get 8 with a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 68618.0
Subtracting 920 from 971 leaves us with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 115

On to step 8:
If we divide 516 by 115, we get 4 and a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 686184.0
Subtract 460 from 516 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
If we divide 560 by 115, we get 4 and a remainder of 100.
Put 4 as the next digit of the answer. 
Result so far: 686184.4
The remainder is 100 after subtracting 460 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
When dividing 1000 by 115, we get 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 686184.48
Subtracting 920 from 1000 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
115 goes into 800 6 times with a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 686184.486
Subtract 690 from 800 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 12:
The number 115 fits into 1100 9 times, leaving a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 686184.4869
Deduct 1035 from 1100 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 13:
The number 115 fits into 650 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 686184.48695
Deduct 575 from 650 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
750 divided by 115 is 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 686184.486956
If we take 690 away from 750, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 15:
115 can be fit into 600 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 686184.4869565
If we take 575 away from 600, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 16:
The number 115 fits into 250 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 686184.48695652
Subtract 230 from 250 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 686184.48695652 with a remainder of 2e-08.
