We're dividing 878440 by 29 
We want to figure out the number of times 878440 can be divided by 29.

Step 1:
29 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 29

Advancing to step 2:
29 goes into 87 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 87 from 87 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 29

Moving on to step 3:
29 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 29

On to step 4:
The number 29 fits into 84 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 302.0
Deduct 58 from 84 and we're left with 26.
Take the next digit (4) from the dividend and append it to 26, then repeat: 264 / 29

On to step 5:
The number 29 fits into 264 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 3029.0
Subtracting 261 from 264 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 29

Moving on to step 6:
The number 29 fits into 30 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 30291.0
Deduct 29 from 30 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
29 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 30291.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 29, we get 3 and a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 30291.03
Subtracting 87 from 100 leaves us 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.

Going ahead to step 9:
If we divide 130 by 29, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 30291.034
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.

Advancing to step 10:
When dividing 140 by 29, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 30291.0344
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.

The final outcome is 30291.0344, with a leftover of 0.00024.
