Let's divide 169601 by 90
Let's see how many times 90 fits into 169601.

Step 1:
If we divide 1 by 90, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 90

Moving on to step 2:
When dividing 16 by 90, we get 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 90

On to step 3:
169 divided by 90 is 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 90 away from 169, we end up with 79.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 90

Let's proceed to step 4:
90 can be fit into 796 8 times, resulting in a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we take 720 away from 796, we end up with 76.
Fetch the next digit (0) from the dividend, attach it to 76 and continue: 760 / 90

Let's proceed to step 5:
90 can be fit into 760 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 188.0
Subtracting 720 from 760 leaves us with 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 90

Step 6:
90 goes into 401 4 times with a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 1884.0
If we subtract 360 from 401, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
When dividing 410 by 90, we get 4 with a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 1884.4
The remainder is 50 after subtracting 360 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 1884.45
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
If we divide 500 by 90, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 1884.455
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 1884.455 with a balance of 0.005.
