We look at the division of 77691375 by 959 
We want to figure out the number of times 77691375 can be divided by 959.

Advancing to step 1:
959 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 959

On to step 2:
The number 959 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 959

Step 3:
959 can be fit into 776 0 times, resulting in a remainder of 776.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 776 after subtracting 0 from 776.
Include the next digit (9) from the dividend after 776, then repeat: 7769 / 959

Going ahead to step 4:
When dividing 7769 by 959, we get 8 with a remainder of 97.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 7672 from 7769, we get 97.
Append the next digit (1) from the dividend to 97 and continue with: 971 / 959

Step 5:
971 divided by 959 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtract 959 from 971 to get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 959

Advancing to step 6:
The number 959 fits into 123 0 times, leaving a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 810.0
Subtract 0 from 123 to get 123.
Grab the next digit (7) from the dividend, add it to 123, then carry on: 1237 / 959

On to step 7:
959 can be fit into 1237 1 times, resulting in a remainder of 278.
Use 1 as the next digit of our solution. 
Result so far: 8101.0
If we take 959 away from 1237, we end up with 278.
Grab the next digit (5) from the dividend, add it to 278, then carry on: 2785 / 959

Going ahead to step 8:
The number 959 fits into 2785 2 times, leaving a remainder of 867.
Record the quotient 2 as the next digit in the result. 
Result so far: 81012.0
If we subtract 1918 from 2785, we get 867.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8670, and continue the process.

Step 9:
959 can be fit into 8670 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 81012.9
If we subtract 8631 from 8670, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 10:
959 goes into 390 0 times with a remainder of 390.
The number 0 becomes the next digit in our result. 
Result so far: 81012.9
If we take 0 away from 390, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 11:
If we divide 3900 by 959, we get 4 and a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 81012.904
Deduct 3836 from 3900 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
640 divided by 959 is 0 with a remainder of 640.
The next digit of our result is 0. 
Result so far: 81012.904
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 13:
959 goes into 6400 6 times with a remainder of 646.
The number 6 becomes the next digit in our result. 
Result so far: 81012.90406
If we subtract 5754 from 6400, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

On to step 14:
The number 959 fits into 6460 6 times, leaving a remainder of 706.
The number 6 becomes the next digit in our result. 
Result so far: 81012.904066
Subtracting 5754 from 6460 leaves us with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Our division results in 81012.904066 with a remaining 7.06e-05.
