We look at the division of 19638708 by 660 
We want to figure out the number of times 19638708 can be divided by 660.

Moving on to step 1:
660 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 660

Step 2:
When dividing 19 by 660, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 660

Moving on to step 3:
The number 660 fits into 196 0 times, leaving a remainder of 196.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 196 leaves us with 196.
Bring next digit (3) of the dividend behind the 196 and repeat the process: 1963 / 660

Moving on to step 4:
If we divide 1963 by 660, we get 2 and a remainder of 643.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1320 from 1963, we get 643.
Bring next digit (8) of the dividend behind the 643 and repeat the process: 6438 / 660

Let's proceed to step 5:
6438 divided by 660 is 9 with a remainder of 498.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 5940 away from 6438, we end up with 498.
Grab the next digit (7) from the dividend, add it to 498, then carry on: 4987 / 660

Advancing to step 6:
When dividing 4987 by 660, we get 7 with a remainder of 367.
Write down 7 as next digit of the result. 
Result so far: 297.0
Deduct 4620 from 4987 and we're left with 367.
Bring next digit (0) of the dividend behind the 367 and repeat the process: 3670 / 660

Let's proceed to step 7:
3670 divided by 660 is 5 with a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 2975.0
Subtract 3300 from 3670 to get 370.
Append the next digit (8) from the dividend to 370 and continue with: 3708 / 660

Let's proceed to step 8:
If we divide 3708 by 660, we get 5 and a remainder of 408.
The next digit of our result is 5. 
Result so far: 29755.0
Subtracting 3300 from 3708 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 9:
When dividing 4080 by 660, we get 6 with a remainder of 120.
The number 6 becomes the next digit in our result. 
Result so far: 29755.6
Subtracting 3960 from 4080 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
1200 divided by 660 is 1 with a remainder of 540.
The number 1 becomes the next digit in our result. 
Result so far: 29755.61
If we subtract 660 from 1200, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 11:
The number 660 fits into 5400 8 times, leaving a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 29755.618
If we take 5280 away from 5400, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
660 can be fit into 1200 1 times, resulting in a remainder of 540.
Write down 1 as next digit of the result. 
Result so far: 29755.6181
If we subtract 660 from 1200, we get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 13:
If we divide 5400 by 660, we get 8 and a remainder of 120.
The next digit of our result is 8. 
Result so far: 29755.61818
If we subtract 5280 from 5400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 14:
1200 divided by 660 is 1 with a remainder of 540.
Record the quotient 1 as the next digit in the result. 
Result so far: 29755.618181
If we take 660 away from 1200, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 15:
If we divide 5400 by 660, we get 8 and a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 29755.6181818
The remainder is 120 after subtracting 5280 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 16:
660 goes into 1200 1 times with a remainder of 540.
Use 1 as the next digit of our solution. 
Result so far: 29755.61818181
Deduct 660 from 1200 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

In conclusion, the division gives 29755.61818181 with a balance of 5.4e-07.
