258406 divided by 29 
Our goal is to divide 258406 by 29.

Let's proceed to step 1:
2 divided by 29 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 29

Going ahead to step 2:
25 divided by 29 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 29

Going ahead to step 3:
258 divided by 29 is 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 232 from 258 to get 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 29

Advancing to step 4:
29 goes into 264 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 261 from 264 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 29

Advancing to step 5:
If we divide 30 by 29, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 891.0
The remainder is 1 after subtracting 29 from 30.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 29

Step 6:
29 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 8910.0
Deduct 0 from 16 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
When dividing 160 by 29, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 8910.5
Deduct 145 from 160 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
29 goes into 150 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8910.55
If we subtract 145 from 150, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 8910.55, with a leftover of 0.005.
