We're dividing 170792 by 77 
We want to divide 170792 by 77.

Step 1:
The number 77 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 77

Advancing to step 2:
17 divided by 77 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 77

On to step 3:
170 divided by 77 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 16 after subtracting 154 from 170.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 77

Going ahead to step 4:
77 goes into 167 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 154 from 167, we get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 77

Step 5:
When dividing 139 by 77, we get 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 221.0
Subtract 77 from 139 to get 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 77

Advancing to step 6:
622 divided by 77 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 2218.0
If we subtract 616 from 622, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 77, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 2218.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
77 goes into 600 7 times with a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 2218.07
The remainder is 61 after subtracting 539 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 9:
If we divide 610 by 77, we get 7 and a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 2218.077
Subtract 539 from 610 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 2218.077, and the remainder is 0.0071.
