We divide 821943 by 66
Our goal is to divide 821943 by 66.

Step 1:
The number 66 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 66

Let's proceed to step 2:
If we divide 82 by 66, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 16 after subtracting 66 from 82.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 66

Advancing to step 3:
The number 66 fits into 161 2 times, leaving a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 29 after subtracting 132 from 161.
Grab the next digit (9) from the dividend, add it to 29, then carry on: 299 / 66

Advancing to step 4:
299 divided by 66 is 4 with a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 124.0
The remainder is 35 after subtracting 264 from 299.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 66

On to step 5:
When dividing 354 by 66, we get 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 1245.0
Deduct 330 from 354 and we're left with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 66

Going ahead to step 6:
If we divide 243 by 66, we get 3 and a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 12453.0
Subtract 198 from 243 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
450 divided by 66 is 6 with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 12453.6
If we take 396 away from 450, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
540 divided by 66 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 12453.68
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 66 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 12453.681
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 12453.6818
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
The number 66 fits into 120 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 12453.68181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 12:
If we divide 540 by 66, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 12453.681818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
When dividing 120 by 66, we get 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 12453.6818181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
The number 66 fits into 540 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 12453.68181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 12453.68181818, with a leftover of 1.2e-08.
