We divide 53169 by 90
Our goal is to divide 53169 by 90.

On to step 1:
When dividing 5 by 90, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 90

Let's proceed to step 2:
If we divide 53 by 90, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Include the next digit (1) from the dividend after 53, then repeat: 531 / 90

Moving on to step 3:
531 divided by 90 is 5 with a remainder of 81.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 450 from 531 to get 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 90

Step 4:
If we divide 816 by 90, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Subtract 810 from 816 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 90

Going ahead to step 5:
If we divide 69 by 90, we get 0 and a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 590.0
Subtract 0 from 69 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 6:
90 goes into 690 7 times with a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 590.7
If we take 630 away from 690, we end up 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 7:
600 divided by 90 is 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 590.76
The remainder is 60 after subtracting 540 from 600.
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 8:
90 goes into 600 6 times with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 590.766
If we take 540 away from 600, we end up 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.

The final outcome is 590.766, with a leftover of 0.006.
