We look at the division of 30180472 by 397 
We want to divide 30180472 by 397.

Going ahead to step 1:
When dividing 3 by 397, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 397

On to step 2:
397 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 397

Going ahead to step 3:
If we divide 301 by 397, we get 0 and a remainder of 301.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 301, we end up with 301.
Append the next digit (8) from the dividend to 301 and continue with: 3018 / 397

Advancing to step 4:
The number 397 fits into 3018 7 times, leaving a remainder of 239.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 239 after subtracting 2779 from 3018.
Bring next digit (0) of the dividend behind the 239 and repeat the process: 2390 / 397

Advancing to step 5:
2390 divided by 397 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 76.0
Subtracting 2382 from 2390 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 397

On to step 6:
397 goes into 84 0 times with a remainder of 84.
The next digit of our result is 0. 
Result so far: 760.0
Subtracting 0 from 84 leaves us with 84.
Grab the next digit (7) from the dividend, add it to 84, then carry on: 847 / 397

Advancing to step 7:
The number 397 fits into 847 2 times, leaving a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 7602.0
The remainder is 53 after subtracting 794 from 847.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 397

Step 8:
If we divide 532 by 397, we get 1 and a remainder of 135.
Put 1 as the next digit of the answer. 
Result so far: 76021.0
Deduct 397 from 532 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
If we divide 1350 by 397, we get 3 and a remainder of 159.
The number 3 becomes the next digit in our result. 
Result so far: 76021.3
If we subtract 1191 from 1350, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 10:
If we divide 1590 by 397, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 76021.34
The remainder is 2 after subtracting 1588 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 11:
397 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 76021.34
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
397 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 76021.34
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 76021.34 and a remainder of 0.002.
