Let's divide 77916188 by 985
Our goal is to divide 77916188 by 985.

Advancing to step 1:
When dividing 7 by 985, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 985

Going ahead to step 2:
985 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (9) from the dividend, add it to 77, then carry on: 779 / 985

On to step 3:
If we divide 779 by 985, we get 0 and a remainder of 779.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 779, we get 779.
Bring next digit (1) of the dividend behind the 779 and repeat the process: 7791 / 985

Advancing to step 4:
When dividing 7791 by 985, we get 7 with a remainder of 896.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 6895 from 7791 and we're left with 896.
Append the next digit (6) from the dividend to 896 and continue with: 8966 / 985

Going ahead to step 5:
When dividing 8966 by 985, we get 9 with a remainder of 101.
Use 9 as the next digit of our solution. 
Result so far: 79.0
If we subtract 8865 from 8966, we get 101.
Take the next digit (1) from the dividend and append it to 101, then repeat: 1011 / 985

Moving on to step 6:
1011 divided by 985 is 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 791.0
The remainder is 26 after subtracting 985 from 1011.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 985

On to step 7:
985 can be fit into 268 0 times, resulting in a remainder of 268.
The next digit of our result is 0. 
Result so far: 7910.0
The remainder is 268 after subtracting 0 from 268.
Grab the next digit (8) from the dividend, add it to 268, then carry on: 2688 / 985

Step 8:
2688 divided by 985 is 2 with a remainder of 718.
Put 2 as the next digit of the answer. 
Result so far: 79102.0
Subtract 1970 from 2688 to get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Moving on to step 9:
985 can be fit into 7180 7 times, resulting in a remainder of 285.
Record the quotient 7 as the next digit in the result. 
Result so far: 79102.7
Subtracting 6895 from 7180 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 10:
If we divide 2850 by 985, we get 2 and a remainder of 880.
Write down 2 as next digit of the result. 
Result so far: 79102.72
If we take 1970 away from 2850, we end up with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Advancing to step 11:
When dividing 8800 by 985, we get 8 with a remainder of 920.
Use 8 as the next digit of our solution. 
Result so far: 79102.728
Subtract 7880 from 8800 to get 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

Step 12:
985 can be fit into 9200 9 times, resulting in a remainder of 335.
The number 9 becomes the next digit in our result. 
Result so far: 79102.7289
If we take 8865 away from 9200, we end up with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 13:
985 goes into 3350 3 times with a remainder of 395.
Write down 3 as next digit of the result. 
Result so far: 79102.72893
If we take 2955 away from 3350, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 14:
When dividing 3950 by 985, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 79102.728934
The remainder is 10 after subtracting 3940 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 15:
985 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 79102.728934
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 16:
985 goes into 1000 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 79102.72893401
Subtracting 985 from 1000 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 79102.72893401 with a remainder of 1.5e-08.
