Let's divide 904043 by 30
We want to figure out the number of times 904043 can be divided by 30.

Going ahead to step 1:
The number 30 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 30

Step 2:
When dividing 90 by 30, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 90 from 90 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 30

Advancing to step 3:
The number 30 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 30

On to step 4:
30 can be fit into 40 1 times, resulting in a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 301.0
The remainder is 10 after subtracting 30 from 40.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 30

Advancing to step 5:
If we divide 104 by 30, we get 3 and a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3013.0
The remainder is 14 after subtracting 90 from 104.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 30

Step 6:
143 divided by 30 is 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 30134.0
Subtracting 120 from 143 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
30 can be fit into 230 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 30134.7
The remainder is 20 after subtracting 210 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 30134.76
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 30, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 30134.766
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 30134.766, and the remainder is 0.002.
