We're dividing 304214 by 90 
We want to divide 304214 by 90.

Advancing to step 1:
The number 90 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 90

On to step 2:
90 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 90

On to step 3:
90 goes into 304 3 times with a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 270 from 304, we get 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 90

On to step 4:
90 goes into 342 3 times with a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Deduct 270 from 342 and we're left with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 90

On to step 5:
If we divide 721 by 90, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 338.0
If we take 720 away from 721, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 90

Advancing to step 6:
If we divide 14 by 90, we get 0 and a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 3380.0
If we subtract 0 from 14, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
90 can be fit into 140 1 times, resulting in a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 3380.1
If we take 90 away from 140, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
90 can be fit into 500 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3380.15
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
If we divide 500 by 90, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 3380.155
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 3380.155, with a leftover of 0.005.
