74371917 ÷ 660 
We're looking to find how many times 660 goes into 74371917.

Step 1:
When dividing 7 by 660, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 660

Moving on to step 2:
74 divided by 660 is 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 660

Moving on to step 3:
660 goes into 743 1 times with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 660 from 743 leaves us with 83.
Bring next digit (7) of the dividend behind the 83 and repeat the process: 837 / 660

Let's proceed to step 4:
If we divide 837 by 660, we get 1 and a remainder of 177.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 177 after subtracting 660 from 837.
Take the next digit (1) from the dividend and append it to 177, then repeat: 1771 / 660

Step 5:
660 goes into 1771 2 times with a remainder of 451.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we subtract 1320 from 1771, we get 451.
Include the next digit (9) from the dividend after 451, then repeat: 4519 / 660

Step 6:
If we divide 4519 by 660, we get 6 and a remainder of 559.
Record the quotient 6 as the next digit in the result. 
Result so far: 1126.0
The remainder is 559 after subtracting 3960 from 4519.
Bring next digit (1) of the dividend behind the 559 and repeat the process: 5591 / 660

On to step 7:
660 can be fit into 5591 8 times, resulting in a remainder of 311.
Put 8 as the next digit of the answer. 
Result so far: 11268.0
If we subtract 5280 from 5591, we get 311.
Append the next digit (7) from the dividend to 311 and continue with: 3117 / 660

Advancing to step 8:
660 goes into 3117 4 times with a remainder of 477.
Record the quotient 4 as the next digit in the result. 
Result so far: 112684.0
Subtracting 2640 from 3117 leaves us with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Step 9:
The number 660 fits into 4770 7 times, leaving a remainder of 150.
The number 7 becomes the next digit in our result. 
Result so far: 112684.7
The remainder is 150 after subtracting 4620 from 4770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
When dividing 1500 by 660, we get 2 with a remainder of 180.
Record the quotient 2 as the next digit in the result. 
Result so far: 112684.72
The remainder is 180 after subtracting 1320 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 11:
If we divide 1800 by 660, we get 2 and a remainder of 480.
The next digit of our result is 2. 
Result so far: 112684.722
If we subtract 1320 from 1800, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final result is 112684.722 with a remainder of 0.048.
