77910531 divided by 985 
We want to figure out the number of times 77910531 can be divided by 985.

On to step 1:
7 divided by 985 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 985

Advancing to step 2:
985 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 985

On to step 3:
If we divide 779 by 985, we get 0 and a remainder of 779.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 779 after subtracting 0 from 779.
Append the next digit (1) from the dividend to 779 and continue with: 7791 / 985

Let's proceed to step 4:
The number 985 fits into 7791 7 times, leaving a remainder of 896.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 6895 from 7791 and we're left with 896.
Include the next digit (0) from the dividend after 896, then repeat: 8960 / 985

On to step 5:
985 can be fit into 8960 9 times, resulting in a remainder of 95.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we subtract 8865 from 8960, we get 95.
Fetch the next digit (5) from the dividend, attach it to 95 and continue: 955 / 985

On to step 6:
The number 985 fits into 955 0 times, leaving a remainder of 955.
Put 0 as the next digit of the answer. 
Result so far: 790.0
Subtract 0 from 955 to get 955.
Include the next digit (3) from the dividend after 955, then repeat: 9553 / 985

Let's proceed to step 7:
The number 985 fits into 9553 9 times, leaving a remainder of 688.
Use 9 as the next digit of our solution. 
Result so far: 7909.0
Subtract 8865 from 9553 to get 688.
Take the next digit (1) from the dividend and append it to 688, then repeat: 6881 / 985

Advancing to step 8:
985 can be fit into 6881 6 times, resulting in a remainder of 971.
Use 6 as the next digit of our solution. 
Result so far: 79096.0
If we subtract 5910 from 6881, we get 971.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9710, and continue the process.

Advancing to step 9:
985 goes into 9710 9 times with a remainder of 845.
Record the quotient 9 as the next digit in the result. 
Result so far: 79096.9
Subtracting 8865 from 9710 leaves us with 845.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8450, and continue the process.

Advancing to step 10:
If we divide 8450 by 985, we get 8 and a remainder of 570.
Use 8 as the next digit of our solution. 
Result so far: 79096.98
The remainder is 570 after subtracting 7880 from 8450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Step 11:
The number 985 fits into 5700 5 times, leaving a remainder of 775.
The number 5 becomes the next digit in our result. 
Result so far: 79096.985
If we subtract 4925 from 5700, we get 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Let's proceed to step 12:
985 can be fit into 7750 7 times, resulting in a remainder of 855.
The next digit of our result is 7. 
Result so far: 79096.9857
If we take 6895 away from 7750, we end up with 855.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8550, and continue the process.

On to step 13:
8550 divided by 985 is 8 with a remainder of 670.
The next digit of our result is 8. 
Result so far: 79096.98578
Deduct 7880 from 8550 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 14:
The number 985 fits into 6700 6 times, leaving a remainder of 790.
Record the quotient 6 as the next digit in the result. 
Result so far: 79096.985786
Subtract 5910 from 6700 to get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 15:
The number 985 fits into 7900 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 79096.9857868
Subtract 7880 from 7900 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.

Let's proceed to step 16:
The number 985 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 79096.9857868
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 79096.9857868, and the remainder is 2e-07.
