We look at the division of 311729 by 77 
Our goal is to divide 311729 by 77.

Advancing to step 1:
77 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 77

Step 2:
When dividing 31 by 77, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 77

Step 3:
The number 77 fits into 311 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 308 from 311 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 77

Moving on to step 4:
77 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 37 leaves us with 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 77

Going ahead to step 5:
The number 77 fits into 372 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 404.0
Subtract 308 from 372 to get 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 77

On to step 6:
If we divide 649 by 77, we get 8 and a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 4048.0
If we subtract 616 from 649, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
77 goes into 330 4 times with a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 4048.4
Subtract 308 from 330 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
220 divided by 77 is 2 with a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 4048.42
Deduct 154 from 220 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
When dividing 660 by 77, we get 8 with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 4048.428
Deduct 616 from 660 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
440 divided by 77 is 5 with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 4048.4285
Subtract 385 from 440 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 11:
77 goes into 550 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 4048.42857
If we subtract 539 from 550, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
77 can be fit into 110 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 4048.428571
Subtracting 77 from 110 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
If we divide 330 by 77, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 4048.4285714
The remainder is 22 after subtracting 308 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
When dividing 220 by 77, we get 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 4048.42857142
The remainder is 66 after subtracting 154 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 4048.42857142, with a leftover of 6.6e-08.
