Let's divide 77987592 by 912
We want to divide 77987592 by 912.

Step 1:
When dividing 7 by 912, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 912

Step 2:
912 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (9) from the dividend to 77 and continue with: 779 / 912

Going ahead to step 3:
The number 912 fits into 779 0 times, leaving a remainder of 779.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 779 after subtracting 0 from 779.
Take the next digit (8) from the dividend and append it to 779, then repeat: 7798 / 912

On to step 4:
7798 divided by 912 is 8 with a remainder of 502.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7296 away from 7798, we end up with 502.
Include the next digit (7) from the dividend after 502, then repeat: 5027 / 912

Advancing to step 5:
If we divide 5027 by 912, we get 5 and a remainder of 467.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we subtract 4560 from 5027, we get 467.
Bring next digit (5) of the dividend behind the 467 and repeat the process: 4675 / 912

Moving on to step 6:
4675 divided by 912 is 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 855.0
If we subtract 4560 from 4675, we get 115.
Append the next digit (9) from the dividend to 115 and continue with: 1159 / 912

Advancing to step 7:
The number 912 fits into 1159 1 times, leaving a remainder of 247.
The number 1 becomes the next digit in our result. 
Result so far: 8551.0
Deduct 912 from 1159 and we're left with 247.
Append the next digit (2) from the dividend to 247 and continue with: 2472 / 912

Moving on to step 8:
If we divide 2472 by 912, we get 2 and a remainder of 648.
Write down 2 as next digit of the result. 
Result so far: 85512.0
Subtract 1824 from 2472 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 9:
If we divide 6480 by 912, we get 7 and a remainder of 96.
The number 7 becomes the next digit in our result. 
Result so far: 85512.7
Subtract 6384 from 6480 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 10:
960 divided by 912 is 1 with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 85512.71
Subtracting 912 from 960 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
480 divided by 912 is 0 with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 85512.71
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 12:
912 can be fit into 4800 5 times, resulting in a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 85512.7105
If we take 4560 away from 4800, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
2400 divided by 912 is 2 with a remainder of 576.
Use 2 as the next digit of our solution. 
Result so far: 85512.71052
If we take 1824 away from 2400, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 14:
912 goes into 5760 6 times with a remainder of 288.
The next digit of our result is 6. 
Result so far: 85512.710526
The remainder is 288 after subtracting 5472 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 15:
912 can be fit into 2880 3 times, resulting in a remainder of 144.
The number 3 becomes the next digit in our result. 
Result so far: 85512.7105263
Subtracting 2736 from 2880 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 16:
The number 912 fits into 1440 1 times, leaving a remainder of 528.
The number 1 becomes the next digit in our result. 
Result so far: 85512.71052631
Subtract 912 from 1440 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

In conclusion, the division gives 85512.71052631 with a balance of 5.28e-07.
