We look at the division of 160589 by 90 
Our goal is to divide 160589 by 90.

Let's proceed to 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.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 90

Let's proceed to step 2:
If we divide 16 by 90, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 90

Let's proceed to step 3:
90 goes into 160 1 times with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 90 from 160 leaves us with 70.
Grab the next digit (5) from the dividend, add it to 70, then carry on: 705 / 90

Moving on to step 4:
705 divided by 90 is 7 with a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 630 from 705 and we're left with 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 90

Moving on to step 5:
The number 90 fits into 758 8 times, leaving a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
The remainder is 38 after subtracting 720 from 758.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 90

Going ahead to step 6:
The number 90 fits into 389 4 times, leaving a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 1784.0
The remainder is 29 after subtracting 360 from 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
90 goes into 290 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 1784.3
If we take 270 away from 290, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 1784.32
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
If we divide 200 by 90, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1784.322
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 1784.322, with a leftover of 0.002.
