We look at the division of 857632 by 66 
Let's see how many times 66 fits into 857632.

Let's proceed 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
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 66

Advancing to step 2:
When dividing 85 by 66, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 66 from 85 to get 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 66

On to step 3:
66 can be fit into 197 2 times, resulting in a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 65 after subtracting 132 from 197.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 66

Going ahead to step 4:
66 can be fit into 656 9 times, resulting in a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we subtract 594 from 656, we get 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 66

Going ahead to step 5:
The number 66 fits into 623 9 times, leaving a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 1299.0
Deduct 594 from 623 and we're left with 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 66

Moving on to step 6:
If we divide 292 by 66, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 12994.0
The remainder is 28 after subtracting 264 from 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
If we divide 280 by 66, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 12994.4
If we subtract 264 from 280, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
160 divided by 66 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 12994.42
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
The number 66 fits into 280 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 12994.424
Subtracting 264 from 280 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 66, we get 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 12994.4242
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
The number 66 fits into 280 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 12994.42424
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
66 can be fit into 160 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 12994.424242
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
When dividing 280 by 66, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 12994.4242424
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
If we divide 160 by 66, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 12994.42424242
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 12994.42424242, with a leftover of 2.8e-08.
