Let's divide 832421 by 77
We want to figure out the number of times 832421 can be divided by 77.

Step 1:
8 divided by 77 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 77

Let's proceed to step 2:
77 goes into 83 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 77 from 83 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 77

On to step 3:
The number 77 fits into 62 0 times, leaving a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 62, we get 62.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 77

Going ahead to step 4:
If we divide 624 by 77, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtracting 616 from 624 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 77

Let's proceed to step 5:
82 divided by 77 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1081.0
The remainder is 5 after subtracting 77 from 82.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 77

On to step 6:
When dividing 51 by 77, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 10810.0
Deduct 0 from 51 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
If we divide 510 by 77, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 10810.6
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 8:
77 goes into 480 6 times with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 10810.66
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 10810.66 with a remainder of 0.018.
