We divide 20309588 by 688
Let's see how many times 688 fits into 20309588.

On to step 1:
If we divide 2 by 688, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 688

Step 2:
The number 688 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 688

Let's proceed to step 3:
688 goes into 203 0 times with a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 203 to get 203.
Append the next digit (0) from the dividend to 203 and continue with: 2030 / 688

Moving on to step 4:
688 goes into 2030 2 times with a remainder of 654.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 654 after subtracting 1376 from 2030.
Append the next digit (9) from the dividend to 654 and continue with: 6549 / 688

Advancing to step 5:
When dividing 6549 by 688, we get 9 with a remainder of 357.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 6192 from 6549 leaves us with 357.
Fetch the next digit (5) from the dividend, attach it to 357 and continue: 3575 / 688

Let's proceed to step 6:
3575 divided by 688 is 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 295.0
Subtract 3440 from 3575 to get 135.
Include the next digit (8) from the dividend after 135, then repeat: 1358 / 688

Going ahead to step 7:
1358 divided by 688 is 1 with a remainder of 670.
Write down 1 as next digit of the result. 
Result so far: 2951.0
If we take 688 away from 1358, we end up with 670.
Include the next digit (8) from the dividend after 670, then repeat: 6708 / 688

Moving on to step 8:
688 goes into 6708 9 times with a remainder of 516.
Use 9 as the next digit of our solution. 
Result so far: 29519.0
Subtracting 6192 from 6708 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 9:
The number 688 fits into 5160 7 times, leaving a remainder of 344.
The next digit of our result is 7. 
Result so far: 29519.7
Subtracting 4816 from 5160 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 10:
If we divide 3440 by 688, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 29519.75
Deduct 3440 from 3440 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 688 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29519.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
If we divide 0 by 688, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29519.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 29519.75 with a remainder of 0.0.
