812645 divided by 66 
We want to divide 812645 by 66.

Step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 66

Moving on to step 2:
66 can be fit into 81 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 66 away from 81, we end up with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 66

On to step 3:
The number 66 fits into 152 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 132 from 152 and we're left with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 66

On to step 4:
66 can be fit into 206 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtract 198 from 206 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 66

Step 5:
When dividing 84 by 66, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1231.0
If we take 66 away from 84, we end up with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 66

Moving on to step 6:
66 goes into 185 2 times with a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 12312.0
Subtracting 132 from 185 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
66 goes into 530 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 12312.8
Subtract 528 from 530 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 12312.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 12312.803
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
20 divided by 66 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 12312.803
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
66 goes into 200 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 12312.80303
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
66 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 12312.80303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
The number 66 fits into 200 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 12312.8030303
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
66 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12312.8030303
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 12312.8030303 with a remainder of 2e-08.
