157597 ÷ 90 
We're looking to find how many times 90 goes into 157597.

Moving on to step 1:
90 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 90

Moving on to step 2:
90 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 90

Let's proceed to step 3:
When dividing 157 by 90, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 67 after subtracting 90 from 157.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 90

On to step 4:
90 goes into 675 7 times with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 45 after subtracting 630 from 675.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 90

Let's proceed to step 5:
When dividing 459 by 90, we get 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 175.0
If we subtract 450 from 459, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 90

On to step 6:
If we divide 97 by 90, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1751.0
The remainder is 7 after subtracting 90 from 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 90 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 1751.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
700 divided by 90 is 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 1751.07
If we subtract 630 from 700, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 1751.077
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.

The final outcome is 1751.077, with a leftover of 0.007.
