We divide 478735 by 90
Our goal is to divide 478735 by 90.

On to step 1:
The number 90 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 90

On to step 2:
90 goes into 47 0 times with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 90

Let's proceed to step 3:
90 goes into 478 5 times with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 28 after subtracting 450 from 478.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 90

On to step 4:
90 goes into 287 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 270 from 287 leaves us with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 90

Advancing to step 5:
The number 90 fits into 173 1 times, leaving a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 531.0
Subtracting 90 from 173 leaves us with 83.
Grab the next digit (5) from the dividend, add it to 83, then carry on: 835 / 90

Let's proceed to step 6:
90 goes into 835 9 times with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 5319.0
If we subtract 810 from 835, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
90 goes into 250 2 times with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 5319.2
The remainder is 70 after subtracting 180 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
90 goes into 700 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 5319.27
If we take 630 away from 700, we end up 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.

Moving on to step 9:
90 goes into 700 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 5319.277
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.

After the division, we end up with 5319.277 and a remainder of 0.007.
