We're dividing 72125064 by 397 
We want to divide 72125064 by 397.

Step 1:
If we divide 7 by 397, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 397

Advancing to step 2:
When dividing 72 by 397, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 397

On to step 3:
When dividing 721 by 397, we get 1 with a remainder of 324.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 397 away from 721, we end up with 324.
Fetch the next digit (2) from the dividend, attach it to 324 and continue: 3242 / 397

Let's proceed to step 4:
When dividing 3242 by 397, we get 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 3176 from 3242 and we're left with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 397

Moving on to step 5:
665 divided by 397 is 1 with a remainder of 268.
The next digit of our result is 1. 
Result so far: 181.0
The remainder is 268 after subtracting 397 from 665.
Include the next digit (0) from the dividend after 268, then repeat: 2680 / 397

Going ahead to step 6:
When dividing 2680 by 397, we get 6 with a remainder of 298.
Put 6 as the next digit of the answer. 
Result so far: 1816.0
Deduct 2382 from 2680 and we're left with 298.
Append the next digit (6) from the dividend to 298 and continue with: 2986 / 397

Going ahead to step 7:
The number 397 fits into 2986 7 times, leaving a remainder of 207.
Record the quotient 7 as the next digit in the result. 
Result so far: 18167.0
If we take 2779 away from 2986, we end up with 207.
Take the next digit (4) from the dividend and append it to 207, then repeat: 2074 / 397

Going ahead to step 8:
The number 397 fits into 2074 5 times, leaving a remainder of 89.
Record the quotient 5 as the next digit in the result. 
Result so far: 181675.0
The remainder is 89 after subtracting 1985 from 2074.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 9:
397 can be fit into 890 2 times, resulting in a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 181675.2
Deduct 794 from 890 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 10:
The number 397 fits into 960 2 times, leaving a remainder of 166.
Write down 2 as next digit of the result. 
Result so far: 181675.22
Subtracting 794 from 960 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The quotient of the division is 181675.22, and the remainder is 0.166.
