Let's divide 19565112 by 688
The aim is to understand the frequency of 688 in 19565112.

Advancing to step 1:
688 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 688

Moving on to step 2:
688 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 688

On to step 3:
688 goes into 195 0 times with a remainder of 195.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 195 to get 195.
Append the next digit (6) from the dividend to 195 and continue with: 1956 / 688

Let's proceed to step 4:
The number 688 fits into 1956 2 times, leaving a remainder of 580.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1376 from 1956 leaves us with 580.
Bring next digit (5) of the dividend behind the 580 and repeat the process: 5805 / 688

Advancing to step 5:
688 goes into 5805 8 times with a remainder of 301.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 5504 from 5805 to get 301.
Bring next digit (1) of the dividend behind the 301 and repeat the process: 3011 / 688

Let's proceed to step 6:
688 can be fit into 3011 4 times, resulting in a remainder of 259.
Write down 4 as next digit of the result. 
Result so far: 284.0
Subtract 2752 from 3011 to get 259.
Grab the next digit (1) from the dividend, add it to 259, then carry on: 2591 / 688

Going ahead to step 7:
688 goes into 2591 3 times with a remainder of 527.
Put 3 as the next digit of the answer. 
Result so far: 2843.0
If we take 2064 away from 2591, we end up with 527.
Append the next digit (2) from the dividend to 527 and continue with: 5272 / 688

Going ahead to step 8:
When dividing 5272 by 688, we get 7 with a remainder of 456.
Record the quotient 7 as the next digit in the result. 
Result so far: 28437.0
If we subtract 4816 from 5272, we get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 9:
4560 divided by 688 is 6 with a remainder of 432.
Use 6 as the next digit of our solution. 
Result so far: 28437.6
The remainder is 432 after subtracting 4128 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 10:
The number 688 fits into 4320 6 times, leaving a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 28437.66
Deduct 4128 from 4320 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final outcome is 28437.66, with a leftover of 0.192.
