We look at the division of 72080176 by 688 
The aim is to understand the frequency of 688 in 72080176.

Going ahead to step 1:
7 divided by 688 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 688

Let's proceed to step 2:
688 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 688

Let's proceed to step 3:
The number 688 fits into 720 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 688 from 720, we get 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 688

Let's proceed to step 4:
If we divide 328 by 688, we get 0 and a remainder of 328.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 328 after subtracting 0 from 328.
Fetch the next digit (0) from the dividend, attach it to 328 and continue: 3280 / 688

Advancing to step 5:
3280 divided by 688 is 4 with a remainder of 528.
Use 4 as the next digit of our solution. 
Result so far: 104.0
Subtract 2752 from 3280 to get 528.
Append the next digit (1) from the dividend to 528 and continue with: 5281 / 688

On to step 6:
5281 divided by 688 is 7 with a remainder of 465.
The number 7 becomes the next digit in our result. 
Result so far: 1047.0
Subtract 4816 from 5281 to get 465.
Include the next digit (7) from the dividend after 465, then repeat: 4657 / 688

Step 7:
688 can be fit into 4657 6 times, resulting in a remainder of 529.
Write down 6 as next digit of the result. 
Result so far: 10476.0
If we subtract 4128 from 4657, we get 529.
Take the next digit (6) from the dividend and append it to 529, then repeat: 5296 / 688

Moving on to step 8:
688 goes into 5296 7 times with a remainder of 480.
Use 7 as the next digit of our solution. 
Result so far: 104767.0
Deduct 4816 from 5296 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 9:
When dividing 4800 by 688, we get 6 with a remainder of 672.
Put 6 as the next digit of the answer. 
Result so far: 104767.6
If we take 4128 away from 4800, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 10:
688 goes into 6720 9 times with a remainder of 528.
Use 9 as the next digit of our solution. 
Result so far: 104767.69
Subtracting 6192 from 6720 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 11:
If we divide 5280 by 688, we get 7 and a remainder of 464.
The number 7 becomes the next digit in our result. 
Result so far: 104767.697
The remainder is 464 after subtracting 4816 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 12:
When dividing 4640 by 688, we get 6 with a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 104767.6976
Deduct 4128 from 4640 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 13:
688 goes into 5120 7 times with a remainder of 304.
The number 7 becomes the next digit in our result. 
Result so far: 104767.69767
Deduct 4816 from 5120 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 14:
When dividing 3040 by 688, we get 4 with a remainder of 288.
Write down 4 as next digit of the result. 
Result so far: 104767.697674
The remainder is 288 after subtracting 2752 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Advancing to step 15:
688 goes into 2880 4 times with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 104767.6976744
Deduct 2752 from 2880 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 104767.6976744, with a leftover of 1.28e-06.
