77987 ÷ 85 
Let's see how many times 85 fits into 77987.

Advancing to step 1:
When dividing 7 by 85, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 85

Going ahead to step 2:
85 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 85

Moving on to step 3:
The number 85 fits into 779 9 times, leaving a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 765 from 779 leaves us with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 85

On to step 4:
If we divide 148 by 85, we get 1 and a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Deduct 85 from 148 and we're left with 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 85

On to step 5:
When dividing 637 by 85, we get 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 917.0
Subtracting 595 from 637 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 6:
If we divide 420 by 85, we get 4 and a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 917.4
Deduct 340 from 420 and we're left 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.

Going ahead to step 7:
85 goes into 800 9 times with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 917.49
If we subtract 765 from 800, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
If we divide 350 by 85, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 917.494
Subtracting 340 from 350 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 917.4941
Deduct 85 from 100 and we're left 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.

Step 10:
85 can be fit into 150 1 times, resulting in a remainder of 65.
The next digit of our result is 1. 
Result so far: 917.49411
Deduct 85 from 150 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.

The quotient of the division is 917.49411, and the remainder is 6.5e-05.
