We look at the division of 812090 by 66 
We're looking to find how many times 66 goes into 812090.

On to step 1:
8 divided by 66 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 66

Let's proceed to step 2:
The number 66 fits into 81 1 times, leaving 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.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 66

Going ahead to step 3:
152 divided by 66 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 132 from 152, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 66

Going ahead to step 4:
The number 66 fits into 200 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we subtract 198 from 200, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 66

Advancing to step 5:
When dividing 29 by 66, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 1230.0
Subtracting 0 from 29 leaves us with 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 66

Step 6:
The number 66 fits into 290 4 times, leaving a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 12304.0
The remainder is 26 after subtracting 264 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
When dividing 260 by 66, we get 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 12304.3
Subtract 198 from 260 to get 62.
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:
If we divide 620 by 66, we get 9 and a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 12304.39
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:
If we divide 260 by 66, we get 3 and a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 12304.393
Subtracting 198 from 260 leaves us with 62.
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 10:
When dividing 620 by 66, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 12304.3939
If we take 594 away from 620, we end up 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.

Advancing to step 11:
66 goes into 260 3 times with a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 12304.39393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 12:
66 can be fit into 620 9 times, resulting in a remainder of 26.
The next digit of our result is 9. 
Result so far: 12304.393939
If we take 594 away from 620, we end up 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.

Step 13:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 12304.3939393
If we subtract 198 from 260, we get 62.
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 14:
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: 12304.39393939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 12304.39393939, and the remainder is 2.6e-08.
