We look at the division of 851433 by 66 
Our goal is to divide 851433 by 66.

Moving on to step 1:
The number 66 fits into 8 0 times, leaving 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.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 66

Advancing to step 2:
66 goes into 85 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 66 from 85 leaves us with 19.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 66

Let's proceed to step 3:
191 divided by 66 is 2 with a remainder of 59.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 132 away from 191, we end up with 59.
Append the next digit (4) from the dividend to 59 and continue with: 594 / 66

Moving on to step 4:
66 goes into 594 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 129.0
Deduct 594 from 594 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 66

Advancing to step 5:
When dividing 3 by 66, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 1290.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 66

Going ahead to step 6:
When dividing 33 by 66, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 12900.0
Deduct 0 from 33 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
When dividing 330 by 66, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12900.5
Subtracting 330 from 330 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
66 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12900.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
66 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12900.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 12900.5 with a remainder of 0.0.
