454217 ÷ 66 
Let's see how many times 66 fits into 454217.

Let's proceed to step 1:
The number 66 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 66

Moving on to step 2:
66 goes into 45 0 times with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 66

On to step 3:
When dividing 454 by 66, we get 6 with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 396 from 454 to get 58.
Fetch the next digit (2) from the dividend, attach it to 58 and continue: 582 / 66

Advancing to step 4:
When dividing 582 by 66, we get 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
The remainder is 54 after subtracting 528 from 582.
Bring next digit (1) of the dividend behind the 54 and repeat the process: 541 / 66

Advancing to step 5:
66 can be fit into 541 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 688.0
Subtract 528 from 541 to get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 66

Going ahead to step 6:
When dividing 137 by 66, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 6882.0
If we subtract 132 from 137, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 66, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 6882.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
500 divided by 66 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 6882.07
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
380 divided by 66 is 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 6882.075
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
500 divided by 66 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 6882.0757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
The number 66 fits into 380 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 6882.07575
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
500 divided by 66 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 6882.075757
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
If we divide 380 by 66, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 6882.0757575
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
When dividing 500 by 66, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 6882.07575757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 6882.07575757 with a remaining 3.8e-08.
