We look at the division of 9742232 by 688 
The aim is to understand the frequency of 688 in 9742232.

Step 1:
688 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 688

Going ahead to step 2:
97 divided by 688 is 0 with a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Grab the next digit (4) from the dividend, add it to 97, then carry on: 974 / 688

Let's proceed to step 3:
When dividing 974 by 688, we get 1 with a remainder of 286.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 688 from 974, we get 286.
Bring next digit (2) of the dividend behind the 286 and repeat the process: 2862 / 688

Advancing to step 4:
When dividing 2862 by 688, we get 4 with a remainder of 110.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2752 from 2862, we get 110.
Bring next digit (2) of the dividend behind the 110 and repeat the process: 1102 / 688

On to step 5:
688 goes into 1102 1 times with a remainder of 414.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Subtracting 688 from 1102 leaves us with 414.
Grab the next digit (3) from the dividend, add it to 414, then carry on: 4143 / 688

Let's proceed to step 6:
688 can be fit into 4143 6 times, resulting in a remainder of 15.
The next digit of our result is 6. 
Result so far: 1416.0
Subtract 4128 from 4143 to get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 688

Advancing to step 7:
152 divided by 688 is 0 with a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 14160.0
Deduct 0 from 152 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 8:
When dividing 1520 by 688, we get 2 with a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 14160.2
The remainder is 144 after subtracting 1376 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 9:
688 can be fit into 1440 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 14160.22
The remainder is 64 after subtracting 1376 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 14160.22 and a remainder of 0.064.
