We look at the division of 40128931 by 930 
We're looking to find how many times 930 goes into 40128931.

On to step 1:
930 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 930

On to step 2:
930 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 930

Advancing to step 3:
When dividing 401 by 930, we get 0 with a remainder of 401.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 401, we get 401.
Bring next digit (2) of the dividend behind the 401 and repeat the process: 4012 / 930

Moving on to step 4:
930 can be fit into 4012 4 times, resulting in a remainder of 292.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 3720 from 4012 to get 292.
Append the next digit (8) from the dividend to 292 and continue with: 2928 / 930

Going ahead to step 5:
The number 930 fits into 2928 3 times, leaving a remainder of 138.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 2790 from 2928 and we're left with 138.
Append the next digit (9) from the dividend to 138 and continue with: 1389 / 930

Going ahead to step 6:
If we divide 1389 by 930, we get 1 and a remainder of 459.
Put 1 as the next digit of the answer. 
Result so far: 431.0
If we take 930 away from 1389, we end up with 459.
Append the next digit (3) from the dividend to 459 and continue with: 4593 / 930

Going ahead to step 7:
4593 divided by 930 is 4 with a remainder of 873.
Record the quotient 4 as the next digit in the result. 
Result so far: 4314.0
If we take 3720 away from 4593, we end up with 873.
Append the next digit (1) from the dividend to 873 and continue with: 8731 / 930

On to step 8:
The number 930 fits into 8731 9 times, leaving a remainder of 361.
The number 9 becomes the next digit in our result. 
Result so far: 43149.0
Subtract 8370 from 8731 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Let's proceed to step 9:
3610 divided by 930 is 3 with a remainder of 820.
The next digit of our result is 3. 
Result so far: 43149.3
Deduct 2790 from 3610 and we're left with 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

On to step 10:
The number 930 fits into 8200 8 times, leaving a remainder of 760.
Record the quotient 8 as the next digit in the result. 
Result so far: 43149.38
If we subtract 7440 from 8200, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 11:
7600 divided by 930 is 8 with a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 43149.388
If we subtract 7440 from 7600, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

After the division, we end up with 43149.388 and a remainder of 0.016.
