We're dividing 451200 by 66 
We're looking to find how many times 66 goes into 451200.

Let's proceed to step 1:
When dividing 4 by 66, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 66

Going ahead to step 2:
If we divide 45 by 66, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (1) from the dividend to 45 and continue with: 451 / 66

Advancing to step 3:
When dividing 451 by 66, we get 6 with a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 396 from 451 leaves us with 55.
Fetch the next digit (2) from the dividend, attach it to 55 and continue: 552 / 66

Step 4:
When dividing 552 by 66, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 68.0
Subtract 528 from 552 to get 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 66

Going ahead to step 5:
66 goes into 240 3 times with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 683.0
Deduct 198 from 240 and we're left with 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 66

On to step 6:
When dividing 420 by 66, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6836.0
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.

Moving on to step 7:
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: 6836.3
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.

Step 8:
420 divided by 66 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 6836.36
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.

Advancing to step 9:
If we divide 240 by 66, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 6836.363
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.

Going ahead to step 10:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6836.3636
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.

Going ahead to step 11:
66 can be fit into 240 3 times, resulting in a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 6836.36363
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.

Step 12:
If we divide 420 by 66, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 6836.363636
If we subtract 396 from 420, 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.

Let's proceed to step 13:
The number 66 fits into 240 3 times, leaving a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 6836.3636363
Subtract 198 from 240 to 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.

On to step 14:
When dividing 420 by 66, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 6836.36363636
Subtract 396 from 420 to 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.

Our division results in 6836.36363636 with a remaining 2.4e-08.
