We look at the division of 66196972 by 315 
Our goal is to divide 66196972 by 315.

Moving on to step 1:
When dividing 6 by 315, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 315

Step 2:
66 divided by 315 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 315

Advancing to step 3:
661 divided by 315 is 2 with a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 630 from 661, we get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 315

Let's proceed to step 4:
315 can be fit into 319 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 315 from 319 leaves us with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 315

Going ahead to step 5:
315 can be fit into 46 0 times, resulting in a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 210.0
If we take 0 away from 46, we end up with 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 315

Step 6:
315 can be fit into 469 1 times, resulting in a remainder of 154.
The number 1 becomes the next digit in our result. 
Result so far: 2101.0
If we subtract 315 from 469, we get 154.
Include the next digit (7) from the dividend after 154, then repeat: 1547 / 315

Going ahead to step 7:
The number 315 fits into 1547 4 times, leaving a remainder of 287.
Use 4 as the next digit of our solution. 
Result so far: 21014.0
If we take 1260 away from 1547, we end up with 287.
Take the next digit (2) from the dividend and append it to 287, then repeat: 2872 / 315

Going ahead to step 8:
If we divide 2872 by 315, we get 9 and a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 210149.0
Subtract 2835 from 2872 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
315 can be fit into 370 1 times, resulting in a remainder of 55.
Put 1 as the next digit of the answer. 
Result so far: 210149.1
Deduct 315 from 370 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
550 divided by 315 is 1 with a remainder of 235.
Record the quotient 1 as the next digit in the result. 
Result so far: 210149.11
If we take 315 away from 550, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Our division results in 210149.11 with a remaining 0.235.
