45614575 ÷ 660 
We're looking to find how many times 660 goes into 45614575.

On to step 1:
4 divided by 660 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 660

Step 2:
660 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 660

On to step 3:
456 divided by 660 is 0 with a remainder of 456.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 456 after subtracting 0 from 456.
Bring next digit (1) of the dividend behind the 456 and repeat the process: 4561 / 660

Advancing to step 4:
When dividing 4561 by 660, we get 6 with a remainder of 601.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 3960 from 4561, we get 601.
Include the next digit (4) from the dividend after 601, then repeat: 6014 / 660

Step 5:
If we divide 6014 by 660, we get 9 and a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 69.0
Deduct 5940 from 6014 and we're left with 74.
Grab the next digit (5) from the dividend, add it to 74, then carry on: 745 / 660

Step 6:
When dividing 745 by 660, we get 1 with a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 691.0
Deduct 660 from 745 and we're left with 85.
Grab the next digit (7) from the dividend, add it to 85, then carry on: 857 / 660

Advancing to step 7:
660 can be fit into 857 1 times, resulting in a remainder of 197.
Write down 1 as next digit of the result. 
Result so far: 6911.0
If we subtract 660 from 857, we get 197.
Bring next digit (5) of the dividend behind the 197 and repeat the process: 1975 / 660

Moving on to step 8:
The number 660 fits into 1975 2 times, leaving a remainder of 655.
Put 2 as the next digit of the answer. 
Result so far: 69112.0
Deduct 1320 from 1975 and we're left with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Step 9:
When dividing 6550 by 660, we get 9 with a remainder of 610.
Use 9 as the next digit of our solution. 
Result so far: 69112.9
Deduct 5940 from 6550 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 10:
660 goes into 6100 9 times with a remainder of 160.
Write down 9 as next digit of the result. 
Result so far: 69112.99
The remainder is 160 after subtracting 5940 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 69112.99 with a balance of 0.16.
