We're dividing 861441 by 66 
We want to divide 861441 by 66.

Going ahead to step 1:
66 can be fit into 8 0 times, resulting in 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.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 66

Moving on to step 2:
66 can be fit into 86 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 66 from 86 to get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 66

Step 3:
201 divided by 66 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 198 from 201 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 66

On to step 4:
The number 66 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 130.0
Subtracting 0 from 34 leaves us with 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 66

Moving on to step 5:
If we divide 344 by 66, we get 5 and a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 1305.0
Subtracting 330 from 344 leaves us with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 66

Moving on to step 6:
The number 66 fits into 141 2 times, leaving a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 13052.0
Deduct 132 from 141 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 66, we get 1 and a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 13052.1
If we subtract 66 from 90, we get 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:
The number 66 fits into 240 3 times, leaving a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 13052.13
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:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 13052.136
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 10:
240 divided by 66 is 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 13052.1363
Deduct 198 from 240 and we're left 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.

On to step 11:
66 goes into 420 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 13052.13636
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.

On to step 12:
66 goes into 240 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 13052.136363
If we subtract 198 from 240, we 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.

Advancing to step 13:
420 divided by 66 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 13052.1363636
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.

Step 14:
240 divided by 66 is 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 13052.13636363
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.

Our division results in 13052.13636363 with a remaining 4.2e-08.
