We're dividing 478288 by 66 
We're looking to find how many times 66 goes into 478288.

Advancing to step 1:
66 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 66

Let's proceed to step 2:
The number 66 fits into 47 0 times, leaving a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Append the next digit (8) from the dividend to 47 and continue with: 478 / 66

Let's proceed to step 3:
478 divided by 66 is 7 with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 462 from 478, we get 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 66

Going ahead to step 4:
66 can be fit into 162 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 132 from 162 and we're left with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 66

Step 5:
If we divide 308 by 66, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 724.0
Subtracting 264 from 308 leaves us with 44.
Include the next digit (8) from the dividend after 44, then repeat: 448 / 66

Advancing to step 6:
If we divide 448 by 66, we get 6 and a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 7246.0
If we take 396 away from 448, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
The number 66 fits into 520 7 times, leaving a remainder of 58.
The next digit of our result is 7. 
Result so far: 7246.7
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
If we divide 580 by 66, we get 8 and a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 7246.78
Subtracting 528 from 580 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
66 can be fit into 520 7 times, resulting in a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 7246.787
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
66 can be fit into 580 8 times, resulting in a remainder of 52.
The next digit of our result is 8. 
Result so far: 7246.7878
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
The number 66 fits into 520 7 times, leaving a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 7246.78787
Subtract 462 from 520 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
66 goes into 580 8 times with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 7246.787878
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
The number 66 fits into 520 7 times, leaving a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 7246.7878787
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 14:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 7246.78787878
If we subtract 528 from 580, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 7246.78787878 with a balance of 5.2e-08.
