We look at the division of 78717777 by 495 
Our goal is to divide 78717777 by 495.

Going ahead to step 1:
The number 495 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 495

Step 2:
495 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 495

Going ahead to step 3:
495 can be fit into 787 1 times, resulting in a remainder of 292.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 495 from 787, we get 292.
Include the next digit (1) from the dividend after 292, then repeat: 2921 / 495

On to step 4:
The number 495 fits into 2921 5 times, leaving a remainder of 446.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 2475 from 2921 to get 446.
Grab the next digit (7) from the dividend, add it to 446, then carry on: 4467 / 495

Moving on to step 5:
495 goes into 4467 9 times with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
Subtract 4455 from 4467 to get 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 495

Going ahead to step 6:
127 divided by 495 is 0 with a remainder of 127.
Use 0 as the next digit of our solution. 
Result so far: 1590.0
Subtract 0 from 127 to get 127.
Include the next digit (7) from the dividend after 127, then repeat: 1277 / 495

On to step 7:
495 goes into 1277 2 times with a remainder of 287.
Write down 2 as next digit of the result. 
Result so far: 15902.0
If we take 990 away from 1277, we end up with 287.
Include the next digit (7) from the dividend after 287, then repeat: 2877 / 495

Advancing to step 8:
495 can be fit into 2877 5 times, resulting in a remainder of 402.
Use 5 as the next digit of our solution. 
Result so far: 159025.0
The remainder is 402 after subtracting 2475 from 2877.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 9:
If we divide 4020 by 495, we get 8 and a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 159025.8
Deduct 3960 from 4020 and we're left with 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 10:
The number 495 fits into 600 1 times, leaving a remainder of 105.
Put 1 as the next digit of the answer. 
Result so far: 159025.81
Deduct 495 from 600 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 11:
The number 495 fits into 1050 2 times, leaving a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 159025.812
Deduct 990 from 1050 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 12:
If we divide 600 by 495, we get 1 and a remainder of 105.
Record the quotient 1 as the next digit in the result. 
Result so far: 159025.8121
Subtracting 495 from 600 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 13:
If we divide 1050 by 495, we get 2 and a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 159025.81212
Deduct 990 from 1050 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
600 divided by 495 is 1 with a remainder of 105.
The number 1 becomes the next digit in our result. 
Result so far: 159025.812121
If we subtract 495 from 600, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 15:
If we divide 1050 by 495, we get 2 and a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 159025.8121212
Subtracting 990 from 1050 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 16:
495 goes into 600 1 times with a remainder of 105.
The next digit of our result is 1. 
Result so far: 159025.81212121
Subtract 495 from 600 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The final outcome is 159025.81212121, with a leftover of 1.05e-07.
