Let's divide 259717 by 90
We want to figure out the number of times 259717 can be divided by 90.

Moving on to step 1:
90 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 90

Going ahead to step 2:
The number 90 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 90

Advancing to step 3:
The number 90 fits into 259 2 times, leaving a remainder of 79.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 180 from 259 and we're left with 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 90

Step 4:
90 goes into 797 8 times with a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 720 from 797 and we're left with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 90

Going ahead to step 5:
When dividing 771 by 90, we get 8 with a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 288.0
Subtracting 720 from 771 leaves us with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 90

Going ahead to step 6:
90 goes into 517 5 times with a remainder of 67.
Record the quotient 5 as the next digit in the result. 
Result so far: 2885.0
Deduct 450 from 517 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 7:
670 divided by 90 is 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 2885.7
If we subtract 630 from 670, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 2885.74
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 2885.744
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 2885.744 with a balance of 0.004.
