30109012 ÷ 474 
We want to divide 30109012 by 474.

Going ahead to step 1:
When dividing 3 by 474, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 474

Advancing to step 2:
The number 474 fits into 30 0 times, leaving 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.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 474

Moving on to step 3:
474 can be fit into 301 0 times, resulting in a remainder of 301.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 301 to get 301.
Take the next digit (0) from the dividend and append it to 301, then repeat: 3010 / 474

Moving on to step 4:
If we divide 3010 by 474, we get 6 and a remainder of 166.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 166 after subtracting 2844 from 3010.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 474

Going ahead to step 5:
474 can be fit into 1669 3 times, resulting in a remainder of 247.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we subtract 1422 from 1669, we get 247.
Include the next digit (0) from the dividend after 247, then repeat: 2470 / 474

On to step 6:
If we divide 2470 by 474, we get 5 and a remainder of 100.
The next digit of our result is 5. 
Result so far: 635.0
Subtracting 2370 from 2470 leaves us with 100.
Include the next digit (1) from the dividend after 100, then repeat: 1001 / 474

Going ahead to step 7:
If we divide 1001 by 474, we get 2 and a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 6352.0
The remainder is 53 after subtracting 948 from 1001.
Append the next digit (2) from the dividend to 53 and continue with: 532 / 474

Let's proceed to step 8:
If we divide 532 by 474, we get 1 and a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 63521.0
Subtracting 474 from 532 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
580 divided by 474 is 1 with a remainder of 106.
The next digit of our result is 1. 
Result so far: 63521.1
Subtracting 474 from 580 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 10:
When dividing 1060 by 474, we get 2 with a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 63521.12
Subtract 948 from 1060 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 11:
474 can be fit into 1120 2 times, resulting in a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 63521.122
Subtract 948 from 1120 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The final result is 63521.122 with a remainder of 0.0172.
