We look at the division of 430384 by 90 
We're looking to find how many times 90 goes into 430384.

Moving on to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 90

Advancing to step 2:
If we divide 43 by 90, we get 0 and a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 90

Let's proceed to step 3:
90 can be fit into 430 4 times, resulting in a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 360 from 430 and we're left with 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 90

Advancing to step 4:
90 goes into 703 7 times with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Deduct 630 from 703 and we're left with 73.
Fetch the next digit (8) from the dividend, attach it to 73 and continue: 738 / 90

On to step 5:
If we divide 738 by 90, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 478.0
Subtract 720 from 738 to get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 90

Advancing to step 6:
When dividing 184 by 90, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 4782.0
Subtracting 180 from 184 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
40 divided by 90 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4782.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 90, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 4782.04
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 90, we get 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 4782.044
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 4782.044 and a remainder of 0.004.
