We look at the division of 688391 by 52 
We're looking to find how many times 52 goes into 688391.

Advancing to step 1:
6 divided by 52 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 52

Going ahead to step 2:
52 goes into 68 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 52 from 68, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 52

Let's proceed to step 3:
When dividing 168 by 52, we get 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 156 from 168 and we're left with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 52

Let's proceed to step 4:
123 divided by 52 is 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 132.0
If we subtract 104 from 123, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 52

Step 5:
If we divide 199 by 52, we get 3 and a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 1323.0
The remainder is 43 after subtracting 156 from 199.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 52

Step 6:
52 can be fit into 431 8 times, resulting in a remainder of 15.
The next digit of our result is 8. 
Result so far: 13238.0
If we subtract 416 from 431, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
If we divide 150 by 52, we get 2 and a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 13238.2
The remainder is 46 after subtracting 104 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
52 can be fit into 460 8 times, resulting in a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 13238.28
The remainder is 44 after subtracting 416 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
52 goes into 440 8 times with a remainder of 24.
The next digit of our result is 8. 
Result so far: 13238.288
If we subtract 416 from 440, we 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.

After the division, we end up with 13238.288 and a remainder of 0.0024.
