Let's divide 458580 by 66
We're looking to find how many times 66 goes into 458580.

Moving on to step 1:
66 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 66

Advancing to step 2:
66 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 66

Let's proceed to step 3:
The number 66 fits into 458 6 times, leaving a remainder of 62.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 62 after subtracting 396 from 458.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 66

Going ahead to step 4:
66 goes into 625 9 times with a remainder of 31.
The next digit of our result is 9. 
Result so far: 69.0
Subtracting 594 from 625 leaves us with 31.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 66

Step 5:
When dividing 318 by 66, we get 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 694.0
Deduct 264 from 318 and we're left with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 66

Step 6:
If we divide 540 by 66, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6948.0
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
If we divide 120 by 66, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 6948.1
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
If we divide 540 by 66, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 6948.18
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
66 goes into 120 1 times with a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 6948.181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 10:
If we divide 540 by 66, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 6948.1818
Deduct 528 from 540 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 66 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 6948.18181
The remainder is 54 after subtracting 66 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
66 goes into 540 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 6948.181818
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
66 goes into 120 1 times with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 6948.1818181
Deduct 66 from 120 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
66 goes into 540 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 6948.18181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 6948.18181818 with a remainder of 1.2e-08.
