We look at the division of 139928 by 77 
We want to divide 139928 by 77.

Going ahead to step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 77

On to step 2:
77 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 77

Let's proceed to step 3:
77 goes into 139 1 times with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 77 from 139 and we're left with 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 77

Step 4:
77 can be fit into 629 8 times, resulting in a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 13 after subtracting 616 from 629.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 77

Moving on to step 5:
77 goes into 132 1 times with a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
If we subtract 77 from 132, we get 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 77

Moving on to step 6:
558 divided by 77 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 1817.0
Subtract 539 from 558 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 77 is 2 with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 1817.2
Subtract 154 from 190 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
77 can be fit into 360 4 times, resulting in a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 1817.24
Subtracting 308 from 360 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
77 can be fit into 520 6 times, resulting in a remainder of 58.
Record the quotient 6 as the next digit in the result. 
Result so far: 1817.246
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
77 can be fit into 580 7 times, resulting in a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 1817.2467
Subtracting 539 from 580 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 11:
77 goes into 410 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1817.24675
Deduct 385 from 410 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
77 goes into 250 3 times with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 1817.246753
Subtract 231 from 250 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
77 can be fit into 190 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 1817.2467532
Subtract 154 from 190 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
If we divide 360 by 77, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 1817.24675324
Subtracting 308 from 360 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 1817.24675324, and the remainder is 5.2e-08.
