390150 ÷ 29 
We want to figure out the number of times 390150 can be divided by 29.

Going ahead to step 1:
If we divide 3 by 29, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 29

Step 2:
29 goes into 39 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 29 from 39 to get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 29

On to step 3:
When dividing 100 by 29, we get 3 with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 87 from 100 to get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 29

Going ahead to step 4:
131 divided by 29 is 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 134.0
The remainder is 15 after subtracting 116 from 131.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 29

Let's proceed to step 5:
When dividing 155 by 29, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1345.0
Subtracting 145 from 155 leaves us with 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 29

Step 6:
29 goes into 100 3 times with a remainder of 13.
The next digit of our result is 3. 
Result so far: 13453.0
If we subtract 87 from 100, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
29 goes into 130 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 13453.4
Subtracting 116 from 130 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
If we divide 140 by 29, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 13453.44
The remainder is 24 after subtracting 116 from 140.
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 result is 13453.44 with a remainder of 0.024.
