Let's divide 408690 by 29
We want to figure out the number of times 408690 can be divided by 29.

Going ahead to step 1:
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: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 29

Step 2:
The number 29 fits into 40 1 times, leaving a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 29 from 40 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 29

Going ahead to step 3:
118 divided by 29 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 116 from 118 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 29

On to step 4:
26 divided by 29 is 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 140.0
Subtract 0 from 26 to get 26.
Bring next digit (9) of the dividend behind the 26 and repeat the process: 269 / 29

Step 5:
If we divide 269 by 29, we get 9 and a remainder of 8.
The next digit of our result is 9. 
Result so far: 1409.0
The remainder is 8 after subtracting 261 from 269.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 29

Going ahead to step 6:
If we divide 80 by 29, we get 2 and a remainder of 22.
The next digit of our result is 2. 
Result so far: 14092.0
Subtract 58 from 80 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
If we divide 220 by 29, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 14092.7
The remainder is 17 after subtracting 203 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
170 divided by 29 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 14092.75
If we take 145 away from 170, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
29 goes into 250 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 14092.758
Subtract 232 from 250 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
If we divide 180 by 29, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 14092.7586
If we take 174 away from 180, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 29, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 14092.75862
If we take 58 away from 60, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
When dividing 20 by 29, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 14092.75862
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
200 divided by 29 is 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 14092.7586206
Subtracting 174 from 200 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
29 can be fit into 260 8 times, resulting in a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 14092.75862068
Deduct 232 from 260 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 14092.75862068 and a remainder of 2.8e-08.
