We divide 259139 by 90
Let's see how many times 90 fits into 259139.

Going ahead to step 1:
If we divide 2 by 90, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 90

On 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
Subtract 0 from 25 to get 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 90

Advancing to step 3:
90 can be fit into 259 2 times, resulting in a remainder of 79.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 180 away from 259, we end up with 79.
Grab the next digit (1) from the dividend, add it to 79, then carry on: 791 / 90

On to step 4:
791 divided by 90 is 8 with a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 720 away from 791, we end up with 71.
Take the next digit (3) from the dividend and append it to 71, then repeat: 713 / 90

Advancing to step 5:
The number 90 fits into 713 7 times, leaving a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 287.0
The remainder is 83 after subtracting 630 from 713.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 90

Going ahead to step 6:
839 divided by 90 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 2879.0
Subtract 810 from 839 to get 29.
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:
When dividing 290 by 90, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 2879.3
Subtracting 270 from 290 leaves us 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:
90 can be fit into 200 2 times, resulting in a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2879.32
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 90, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2879.322
Deduct 180 from 200 and we're left 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.

Our division results in 2879.322 with a remaining 0.002.
