We're dividing 458340 by 66 
We want to figure out the number of times 458340 can be divided by 66.

Step 1:
66 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 66

Going ahead to step 2:
If we divide 45 by 66, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 66

Advancing to step 3:
If we divide 458 by 66, we get 6 and a remainder of 62.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 396 from 458 and we're left with 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 66

Moving on to step 4:
The number 66 fits into 623 9 times, leaving a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 69.0
The remainder is 29 after subtracting 594 from 623.
Take the next digit (4) from the dividend and append it to 29, then repeat: 294 / 66

Step 5:
66 can be fit into 294 4 times, resulting in a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 694.0
If we take 264 away from 294, we end up with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 66

On to step 6:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 6944.0
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 6944.5
Subtract 330 from 360 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
When dividing 300 by 66, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 6944.54
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 6944.545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 6944.5454
Deduct 264 from 300 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
When dividing 360 by 66, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 6944.54545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
If we divide 300 by 66, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 6944.545454
If we subtract 264 from 300, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
66 goes into 360 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 6944.5454545
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
When dividing 300 by 66, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 6944.54545454
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The quotient of the division is 6944.54545454, and the remainder is 3.6e-08.
