Let's divide 481408 by 90
Let's see how many times 90 fits into 481408.

On to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 90

Let's proceed to step 2:
If we divide 48 by 90, we get 0 and a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 90

Moving on to step 3:
If we divide 481 by 90, we get 5 and a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 450 from 481 and we're left with 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 90

Step 4:
90 goes into 314 3 times with a remainder of 44.
The next digit of our result is 3. 
Result so far: 53.0
If we take 270 away from 314, we end up with 44.
Fetch the next digit (0) from the dividend, attach it to 44 and continue: 440 / 90

Advancing to step 5:
440 divided by 90 is 4 with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 534.0
The remainder is 80 after subtracting 360 from 440.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 90

On to step 6:
The number 90 fits into 808 8 times, leaving a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 5348.0
If we subtract 720 from 808, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 7:
When dividing 880 by 90, we get 9 with a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 5348.9
If we subtract 810 from 880, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 5348.97
Deduct 630 from 700 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
When dividing 700 by 90, we get 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 5348.977
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 5348.977 with a remainder of 0.007.
