We're dividing 575639 by 31 
We want to figure out the number of times 575639 can be divided by 31.

On to step 1:
When dividing 5 by 31, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 31

On to step 2:
31 can be fit into 57 1 times, resulting in a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 31 from 57 leaves us with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 31

Advancing to step 3:
265 divided by 31 is 8 with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 17 after subtracting 248 from 265.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 31

Let's proceed to step 4:
31 can be fit into 176 5 times, resulting in a remainder of 21.
The next digit of our result is 5. 
Result so far: 185.0
If we subtract 155 from 176, we get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 31

On to step 5:
31 can be fit into 213 6 times, resulting in a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 1856.0
The remainder is 27 after subtracting 186 from 213.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 31

On to step 6:
31 can be fit into 279 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 18569.0
If we take 279 away from 279, 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.

Moving on to step 7:
If we divide 0 by 31, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18569.0
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.

Moving on to step 8:
31 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18569.0
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 18569.0 with a remainder of 0.0.
