158913 divided by 90 
Our goal is to divide 158913 by 90.

Advancing to step 1:
90 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 90

Let's proceed to step 2:
The number 90 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 90

Step 3:
90 goes into 158 1 times with a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 90 from 158 to get 68.
Fetch the next digit (9) from the dividend, attach it to 68 and continue: 689 / 90

Moving on to step 4:
When dividing 689 by 90, we get 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 59 after subtracting 630 from 689.
Include the next digit (1) from the dividend after 59, then repeat: 591 / 90

Advancing to step 5:
591 divided by 90 is 6 with a remainder of 51.
The next digit of our result is 6. 
Result so far: 176.0
Subtracting 540 from 591 leaves us with 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 90

Step 6:
90 goes into 513 5 times with a remainder of 63.
Put 5 as the next digit of the answer. 
Result so far: 1765.0
Deduct 450 from 513 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
When dividing 630 by 90, we get 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 1765.7
If we subtract 630 from 630, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 90 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1765.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 90, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1765.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 1765.7 with a remainder of 0.0.
