We divide 821379 by 66
Our goal is to divide 821379 by 66.

Moving on to step 1:
If we divide 8 by 66, we get 0 and 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 / 66

Moving on to step 2:
66 goes into 82 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 16 after subtracting 66 from 82.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 66

Moving on to step 3:
66 can be fit into 161 2 times, resulting in a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 132 from 161 leaves us with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 66

Going ahead to step 4:
If we divide 293 by 66, we get 4 and a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtract 264 from 293 to get 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 66

Moving on to step 5:
66 goes into 297 4 times with a remainder of 33.
Use 4 as the next digit of our solution. 
Result so far: 1244.0
If we subtract 264 from 297, we get 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 66

On to step 6:
66 can be fit into 339 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 12445.0
The remainder is 9 after subtracting 330 from 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 66 is 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 12445.1
Deduct 66 from 90 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
If we divide 240 by 66, we get 3 and a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 12445.13
The remainder is 42 after subtracting 198 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 9:
66 goes into 420 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 12445.136
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
If we divide 240 by 66, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 12445.1363
Subtract 198 from 240 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.

Advancing to step 11:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 12445.13636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
240 divided by 66 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 12445.136363
If we subtract 198 from 240, 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.

Step 13:
When dividing 420 by 66, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12445.1363636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
66 goes into 240 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 12445.13636363
If we subtract 198 from 240, 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.

In conclusion, the division gives 12445.13636363 with a balance of 4.2e-08.
