We look at the division of 821758 by 77 
Our goal is to divide 821758 by 77.

Going ahead to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 77

Moving on to step 2:
77 can be fit into 82 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 77 from 82 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 77

Step 3:
51 divided by 77 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 51, we end up with 51.
Take the next digit (7) from the dividend and append it to 51, then repeat: 517 / 77

Moving on to step 4:
The number 77 fits into 517 6 times, leaving a remainder of 55.
The next digit of our result is 6. 
Result so far: 106.0
If we take 462 away from 517, we end up with 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 77

Let's proceed to step 5:
77 can be fit into 555 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 1067.0
Deduct 539 from 555 and we're left with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 77

Let's proceed to step 6:
The number 77 fits into 168 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 10672.0
If we subtract 154 from 168, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
If we divide 140 by 77, we get 1 and a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 10672.1
Deduct 77 from 140 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 8:
630 divided by 77 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 10672.18
Deduct 616 from 630 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
140 divided by 77 is 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 10672.181
If we subtract 77 from 140, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 10:
77 can be fit into 630 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 10672.1818
Subtracting 616 from 630 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
140 divided by 77 is 1 with a remainder of 63.
The next digit of our result is 1. 
Result so far: 10672.18181
Deduct 77 from 140 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 12:
77 goes into 630 8 times with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 10672.181818
If we take 616 away from 630, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
The number 77 fits into 140 1 times, leaving a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 10672.1818181
If we subtract 77 from 140, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 14:
77 can be fit into 630 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 10672.18181818
Subtract 616 from 630 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 10672.18181818, with a leftover of 1.4e-08.
