813525 divided by 66 
We want to divide 813525 by 66.

Advancing to step 1:
The number 66 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 66

Let's proceed to step 2:
When dividing 81 by 66, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 66 from 81, we get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 66

Step 3:
If we divide 153 by 66, we get 2 and a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 21 after subtracting 132 from 153.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 66

Going ahead to step 4:
When dividing 215 by 66, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 123.0
The remainder is 17 after subtracting 198 from 215.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 66

Going ahead to step 5:
66 goes into 172 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 1232.0
If we subtract 132 from 172, we get 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 66

Step 6:
66 can be fit into 405 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 12326.0
The remainder is 9 after subtracting 396 from 405.
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:
When dividing 90 by 66, we get 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 12326.1
If we take 66 away from 90, 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.

Going ahead to step 8:
If we divide 240 by 66, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 12326.13
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.

Advancing to step 9:
When dividing 420 by 66, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 12326.136
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.

Let's proceed to step 10:
When dividing 240 by 66, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 12326.1363
If we take 198 away from 240, we end up 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.

Advancing to step 11:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 12326.13636
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.

Let's proceed to step 12:
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: 12326.136363
Subtracting 198 from 240 leaves us 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.

Going ahead to 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: 12326.1363636
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.

Moving on to step 14:
When dividing 240 by 66, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 12326.13636363
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.

The final result is 12326.13636363 with a remainder of 4.2e-08.
