821396 divided by 66 
We want to figure out the number of times 821396 can be divided by 66.

Going ahead to step 1:
When dividing 8 by 66, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 66

Moving on to step 2:
66 goes into 82 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 66 from 82, we get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 66

Step 3:
66 goes into 161 2 times with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 132 from 161 and we're left with 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 66

Step 4:
If we divide 293 by 66, we get 4 and a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we take 264 away from 293, we end up with 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 66

Going ahead to step 5:
When dividing 299 by 66, we get 4 with a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 1244.0
If we subtract 264 from 299, we get 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 66

Advancing to step 6:
66 can be fit into 356 5 times, resulting in a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 12445.0
Deduct 330 from 356 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
If we divide 260 by 66, we get 3 and a remainder of 62.
The next digit of our result is 3. 
Result so far: 12445.3
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
When dividing 620 by 66, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 12445.39
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
66 goes into 260 3 times with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 12445.393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
The number 66 fits into 620 9 times, leaving a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 12445.3939
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
When dividing 260 by 66, we get 3 with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 12445.39393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
If we divide 620 by 66, we get 9 and a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 12445.393939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
66 goes into 260 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 12445.3939393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
66 can be fit into 620 9 times, resulting in a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 12445.39393939
Subtract 594 from 620 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 12445.39393939 with a remaining 2.6e-08.
