Let's divide 821346 by 66
We want to divide 821346 by 66.

Step 1:
When dividing 8 by 66, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 66

Step 2:
66 goes into 82 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 66 from 82 and we're left with 16.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 66

Going ahead to step 3:
161 divided by 66 is 2 with a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 132 from 161 and we're left with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 66

Step 4:
293 divided by 66 is 4 with 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.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 66

Let's proceed to step 5:
66 goes into 294 4 times with a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 1244.0
Deduct 264 from 294 and we're left with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 66

On to step 6:
If we divide 306 by 66, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 12444.0
If we subtract 264 from 306, 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.

Let's proceed to step 7:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12444.6
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.

Step 8:
66 goes into 240 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 12444.63
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 9:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12444.636
Deduct 396 from 420 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 10:
240 divided by 66 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 12444.6363
Deduct 198 from 240 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.

Moving on to step 11:
66 can be fit into 420 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 12444.63636
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.

Going ahead to step 12:
The number 66 fits into 240 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 12444.636363
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.

Step 13:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 12444.6363636
If we subtract 396 from 420, we get 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 14:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 12444.63636363
Deduct 198 from 240 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.

In conclusion, the division gives 12444.63636363 with a balance of 4.2e-08.
