We divide 412138 by 30
Our goal is to divide 412138 by 30.

Going ahead to step 1:
30 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 30

Advancing to step 2:
30 can be fit into 41 1 times, resulting in a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 30 from 41, we get 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 30

Step 3:
If we divide 112 by 30, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 90 from 112, we get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 30

Step 4:
221 divided by 30 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 137.0
Deduct 210 from 221 and we're left with 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 30

Advancing to step 5:
30 goes into 113 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 1373.0
The remainder is 23 after subtracting 90 from 113.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 30

Advancing to step 6:
238 divided by 30 is 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 13737.0
Subtracting 210 from 238 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
280 divided by 30 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 13737.9
If we take 270 away from 280, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
30 can be fit into 100 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 13737.93
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 13737.933
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 13737.933 with a remaining 0.001.
