We look at the division of 112720 by 68 
The aim is to understand the frequency of 68 in 112720.

Moving on to step 1:
The number 68 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 68

Step 2:
68 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 11, we end up with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 68

Advancing to step 3:
When dividing 112 by 68, we get 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 68 from 112 to get 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 68

Let's proceed to step 4:
If we divide 447 by 68, we get 6 and a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 408 from 447 and we're left with 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 68

Advancing to step 5:
68 goes into 392 5 times with a remainder of 52.
The next digit of our result is 5. 
Result so far: 165.0
If we take 340 away from 392, we end up with 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 68

Going ahead to step 6:
The number 68 fits into 520 7 times, leaving a remainder of 44.
The next digit of our result is 7. 
Result so far: 1657.0
Subtracting 476 from 520 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
68 can be fit into 440 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 1657.6
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
68 goes into 320 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 1657.64
The remainder is 48 after subtracting 272 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
480 divided by 68 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 1657.647
If we subtract 476 from 480, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
40 divided by 68 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1657.647
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
68 goes into 400 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 1657.64705
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 12:
When dividing 600 by 68, we get 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 1657.647058
If we subtract 544 from 600, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
When dividing 560 by 68, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1657.6470588
Subtracting 544 from 560 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 1657.6470588, with a leftover of 1.6e-07.
