39161394 divided by 660 
Our goal is to divide 39161394 by 660.

Going ahead to step 1:
660 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 660

Going ahead to step 2:
The number 660 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 660

Step 3:
If we divide 391 by 660, we get 0 and a remainder of 391.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 391 leaves us with 391.
Bring next digit (6) of the dividend behind the 391 and repeat the process: 3916 / 660

Step 4:
3916 divided by 660 is 5 with a remainder of 616.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 616 after subtracting 3300 from 3916.
Bring next digit (1) of the dividend behind the 616 and repeat the process: 6161 / 660

Moving on to step 5:
660 goes into 6161 9 times with a remainder of 221.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtracting 5940 from 6161 leaves us with 221.
Include the next digit (3) from the dividend after 221, then repeat: 2213 / 660

Moving on to step 6:
When dividing 2213 by 660, we get 3 with a remainder of 233.
Record the quotient 3 as the next digit in the result. 
Result so far: 593.0
If we take 1980 away from 2213, we end up with 233.
Include the next digit (9) from the dividend after 233, then repeat: 2339 / 660

Let's proceed to step 7:
The number 660 fits into 2339 3 times, leaving a remainder of 359.
Record the quotient 3 as the next digit in the result. 
Result so far: 5933.0
Subtract 1980 from 2339 to get 359.
Grab the next digit (4) from the dividend, add it to 359, then carry on: 3594 / 660

Let's proceed to step 8:
The number 660 fits into 3594 5 times, leaving a remainder of 294.
Write down 5 as next digit of the result. 
Result so far: 59335.0
If we subtract 3300 from 3594, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 9:
660 goes into 2940 4 times with a remainder of 300.
Record the quotient 4 as the next digit in the result. 
Result so far: 59335.4
The remainder is 300 after subtracting 2640 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 10:
660 goes into 3000 4 times with a remainder of 360.
The next digit of our result is 4. 
Result so far: 59335.44
If we take 2640 away from 3000, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 59335.44 and a remainder of 0.36.
