We want to divide 128940 by 77.

Going ahead to step 1:
If we divide 1 by 77, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 77

Advancing to step 2:
The number 77 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 77

Moving on to step 3:
When dividing 128 by 77, we get 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 128 to get 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 77

On to step 4:
519 divided by 77 is 6 with a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 462 from 519 to get 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 77

On to step 5:
574 divided by 77 is 7 with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 167.0
If we take 539 away from 574, we end up with 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 77

Going ahead to step 6:

77 goes into 420 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1674.545
Subtracting 385 from 420 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
350 divided by 77 is 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 1674.5454
If we subtract 308 from 350, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.
