We're dividing 869424 by 29 
Let's see how many times 29 fits into 869424.

Advancing to step 1:
The number 29 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 29

On to step 2:
When dividing 86 by 29, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 58 from 86, we get 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 29

Moving on to step 3:
The number 29 fits into 289 9 times, leaving a remainder of 28.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 28 after subtracting 261 from 289.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 29

Let's proceed to step 4:
If we divide 284 by 29, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 299.0
Deduct 261 from 284 and we're left with 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 29

Advancing to step 5:
29 can be fit into 232 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 2998.0
If we take 232 away from 232, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 29

Let's proceed to step 6:
29 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 29980.0
Deduct 0 from 4 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 29 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 29980.1
The remainder is 11 after subtracting 29 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
If we divide 110 by 29, we get 3 and a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 29980.13
Subtract 87 from 110 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
The number 29 fits into 230 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 29980.137
The remainder is 27 after subtracting 203 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
The number 29 fits into 270 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 29980.1379
Subtracting 261 from 270 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 11:
When dividing 90 by 29, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 29980.13793
Subtracting 87 from 90 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
29 goes into 30 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 29980.137931
The remainder is 1 after subtracting 29 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
If we divide 10 by 29, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 29980.137931
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 29980.13793103
Subtract 87 from 100 to 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.

The final result is 29980.13793103 with a remainder of 1.3e-08.
