We're dividing 72130317 by 612 
We want to figure out the number of times 72130317 can be divided by 612.

Going ahead to step 1:
7 divided by 612 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 612

Let's proceed to step 2:
When dividing 72 by 612, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 612

Advancing to step 3:
721 divided by 612 is 1 with a remainder of 109.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 612 from 721 leaves us with 109.
Take the next digit (3) from the dividend and append it to 109, then repeat: 1093 / 612

Let's proceed to step 4:
612 can be fit into 1093 1 times, resulting in a remainder of 481.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 612 from 1093 to get 481.
Take the next digit (0) from the dividend and append it to 481, then repeat: 4810 / 612

Advancing to step 5:
When dividing 4810 by 612, we get 7 with a remainder of 526.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Subtracting 4284 from 4810 leaves us with 526.
Append the next digit (3) from the dividend to 526 and continue with: 5263 / 612

Advancing to step 6:
612 can be fit into 5263 8 times, resulting in a remainder of 367.
The next digit of our result is 8. 
Result so far: 1178.0
Subtracting 4896 from 5263 leaves us with 367.
Grab the next digit (1) from the dividend, add it to 367, then carry on: 3671 / 612

Moving on to step 7:
When dividing 3671 by 612, we get 5 with a remainder of 611.
The number 5 becomes the next digit in our result. 
Result so far: 11785.0
Subtract 3060 from 3671 to get 611.
Fetch the next digit (7) from the dividend, attach it to 611 and continue: 6117 / 612

Going ahead to step 8:
If we divide 6117 by 612, we get 9 and a remainder of 609.
The next digit of our result is 9. 
Result so far: 117859.0
Subtract 5508 from 6117 to get 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

On to step 9:
If we divide 6090 by 612, we get 9 and a remainder of 582.
Write down 9 as next digit of the result. 
Result so far: 117859.9
The remainder is 582 after subtracting 5508 from 6090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Going ahead to step 10:
612 can be fit into 5820 9 times, resulting in a remainder of 312.
Record the quotient 9 as the next digit in the result. 
Result so far: 117859.99
If we take 5508 away from 5820, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 117859.99 with a remainder of 0.312.
