We're dividing 258574 by 29 
We want to figure out the number of times 258574 can be divided by 29.

Going ahead to step 1:
If we divide 2 by 29, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 29

On to step 2:
29 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 29

Step 3:
29 goes into 258 8 times with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 26 after subtracting 232 from 258.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 29

Advancing to step 4:
265 divided by 29 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
If we subtract 261 from 265, we get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 29

Going ahead to step 5:
If we divide 47 by 29, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 891.0
Deduct 29 from 47 and we're left with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 29

Step 6:
29 can be fit into 184 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 8916.0
The remainder is 10 after subtracting 174 from 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
When dividing 100 by 29, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 8916.3
Deduct 87 from 100 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
If we divide 130 by 29, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 8916.34
Subtract 116 from 130 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
The number 29 fits into 140 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8916.344
If we take 116 away from 140, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 8916.344 with a remaining 0.0024.
