686402 ÷ 29 
We want to figure out the number of times 686402 can be divided by 29.

On to step 1:
If we divide 6 by 29, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 29

Advancing to step 2:
29 goes into 68 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 58 from 68, we get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 29

Going ahead to step 3:
29 goes into 106 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 87 from 106 leaves us with 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 29

Advancing to step 4:
When dividing 194 by 29, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 236.0
Deduct 174 from 194 and we're left with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 29

Advancing to step 5:
If we divide 200 by 29, we get 6 and a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 2366.0
Subtracting 174 from 200 leaves us with 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 29

Advancing to step 6:
262 divided by 29 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 23669.0
Subtract 261 from 262 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
If we divide 10 by 29, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 23669.0
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.

Going ahead to step 8:
29 can be fit into 100 3 times, resulting in a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 23669.03
The remainder is 13 after subtracting 87 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
130 divided by 29 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 23669.034
If we take 116 away from 130, we end up 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.

Advancing to step 10:
140 divided by 29 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 23669.0344
Subtract 116 from 140 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 23669.0344 with a balance of 0.00024.
