We look at the division of 19182271 by 688 
The aim is to understand the frequency of 688 in 19182271.

Going ahead to step 1:
1 divided by 688 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 688

Let's proceed to step 2:
688 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 688

Step 3:
The number 688 fits into 191 0 times, leaving a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 191, we end up with 191.
Bring next digit (8) of the dividend behind the 191 and repeat the process: 1918 / 688

On to step 4:
If we divide 1918 by 688, we get 2 and a remainder of 542.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 1376 from 1918 leaves us with 542.
Append the next digit (2) from the dividend to 542 and continue with: 5422 / 688

Let's proceed to step 5:
If we divide 5422 by 688, we get 7 and a remainder of 606.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 4816 from 5422 to get 606.
Fetch the next digit (2) from the dividend, attach it to 606 and continue: 6062 / 688

Going ahead to step 6:
If we divide 6062 by 688, we get 8 and a remainder of 558.
Write down 8 as next digit of the result. 
Result so far: 278.0
Subtract 5504 from 6062 to get 558.
Include the next digit (7) from the dividend after 558, then repeat: 5587 / 688

Let's proceed to step 7:
688 goes into 5587 8 times with a remainder of 83.
Use 8 as the next digit of our solution. 
Result so far: 2788.0
Deduct 5504 from 5587 and we're left with 83.
Take the next digit (1) from the dividend and append it to 83, then repeat: 831 / 688

Going ahead to step 8:
688 goes into 831 1 times with a remainder of 143.
Record the quotient 1 as the next digit in the result. 
Result so far: 27881.0
Subtract 688 from 831 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 9:
When dividing 1430 by 688, we get 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 27881.2
Subtract 1376 from 1430 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
If we divide 540 by 688, we get 0 and a remainder of 540.
The next digit of our result is 0. 
Result so far: 27881.2
If we take 0 away from 540, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Step 11:
5400 divided by 688 is 7 with a remainder of 584.
The next digit of our result is 7. 
Result so far: 27881.207
If we subtract 4816 from 5400, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Moving on to step 12:
688 goes into 5840 8 times with a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 27881.2078
If we subtract 5504 from 5840, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 13:
688 can be fit into 3360 4 times, resulting in a remainder of 608.
Use 4 as the next digit of our solution. 
Result so far: 27881.20784
If we subtract 2752 from 3360, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 14:
688 can be fit into 6080 8 times, resulting in a remainder of 576.
The number 8 becomes the next digit in our result. 
Result so far: 27881.207848
If we subtract 5504 from 6080, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 15:
The number 688 fits into 5760 8 times, leaving a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 27881.2078488
Subtract 5504 from 5760 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final outcome is 27881.2078488, with a leftover of 2.56e-06.
