380454 divided by 90 
We want to figure out the number of times 380454 can be divided by 90.

Let's proceed to step 1:
3 divided by 90 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 90

Let's proceed to step 2:
If we divide 38 by 90, we get 0 and a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 90

Step 3:
90 goes into 380 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 360 from 380 and we're left with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 90

Going ahead to step 4:
If we divide 204 by 90, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 42.0
If we take 180 away from 204, we end up with 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 90

Going ahead to step 5:
90 goes into 245 2 times with a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 422.0
Deduct 180 from 245 and we're left with 65.
Append the next digit (4) from the dividend to 65 and continue with: 654 / 90

Step 6:
When dividing 654 by 90, we get 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 4227.0
The remainder is 24 after subtracting 630 from 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
The number 90 fits into 240 2 times, leaving a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 4227.2
Subtracting 180 from 240 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
If we divide 600 by 90, we get 6 and a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4227.26
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The next digit of our result is 6. 
Result so far: 4227.266
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 4227.266 with a remaining 0.006.
