Let's divide 388325 by 90
Let's see how many times 90 fits into 388325.

Moving on to step 1:
90 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 90

Moving on to step 2:
The number 90 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 90

Advancing to step 3:
If we divide 388 by 90, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 360 from 388 and we're left with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 90

Advancing to step 4:
283 divided by 90 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 270 from 283 and we're left with 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 90

On to step 5:
The number 90 fits into 132 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 431.0
The remainder is 42 after subtracting 90 from 132.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 90

Advancing to step 6:
When dividing 425 by 90, we get 4 with a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 4314.0
Deduct 360 from 425 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
If we divide 650 by 90, we get 7 and a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 4314.7
Subtract 630 from 650 to 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.

Moving on to step 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 4314.72
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 90 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 4314.722
Deduct 180 from 200 and we're left with 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 final outcome is 4314.722, with a leftover of 0.002.
