We look at the division of 991641 by 77 
Our goal is to divide 991641 by 77.

On to step 1:
When dividing 9 by 77, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 77

Going ahead to step 2:
When dividing 99 by 77, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 77 from 99 to get 22.
Include the next digit (1) from the dividend after 22, then repeat: 221 / 77

Moving on to step 3:
The number 77 fits into 221 2 times, leaving a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 154 away from 221, we end up with 67.
Include the next digit (6) from the dividend after 67, then repeat: 676 / 77

Going ahead to step 4:
676 divided by 77 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 128.0
If we subtract 616 from 676, we get 60.
Grab the next digit (4) from the dividend, add it to 60, then carry on: 604 / 77

Moving on to step 5:
The number 77 fits into 604 7 times, leaving a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 1287.0
The remainder is 65 after subtracting 539 from 604.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 77

Let's proceed to step 6:
77 goes into 651 8 times with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 12878.0
Deduct 616 from 651 and we're left 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.

Let's proceed to step 7:
If we divide 350 by 77, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 12878.4
Subtract 308 from 350 to 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.

Moving on to step 8:
The number 77 fits into 420 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 12878.45
Subtract 385 from 420 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
When dividing 350 by 77, we get 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 12878.454
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.

Moving on to step 10:
420 divided by 77 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 12878.4545
If we subtract 385 from 420, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
350 divided by 77 is 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 12878.45454
The remainder is 42 after subtracting 308 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
77 goes into 420 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 12878.454545
Subtract 385 from 420 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
350 divided by 77 is 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 12878.4545454
Deduct 308 from 350 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
If we divide 420 by 77, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 12878.45454545
Deduct 385 from 420 and we're left 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.

The final result is 12878.45454545 with a remainder of 3.5e-08.
