We look at the division of 797157 by 68 
The aim is to understand the frequency of 68 in 797157.

Moving on to step 1:
When dividing 7 by 68, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 68

Going ahead to step 2:
79 divided by 68 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 11 after subtracting 68 from 79.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 68

On to step 3:
If we divide 117 by 68, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 49 after subtracting 68 from 117.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 68

Step 4:
The number 68 fits into 491 7 times, leaving a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Subtracting 476 from 491 leaves us with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 68

Going ahead to step 5:
68 goes into 155 2 times with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 1172.0
Subtracting 136 from 155 leaves us with 19.
Bring next digit (7) of the dividend behind the 19 and repeat the process: 197 / 68

Advancing to step 6:
68 can be fit into 197 2 times, resulting in a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 11722.0
The remainder is 61 after subtracting 136 from 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
68 can be fit into 610 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 11722.8
Deduct 544 from 610 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
The number 68 fits into 660 9 times, leaving a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 11722.89
Subtract 612 from 660 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
If we divide 480 by 68, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 11722.897
The remainder is 4 after subtracting 476 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
When dividing 40 by 68, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 11722.897
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 68 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 11722.89705
Subtracting 340 from 400 leaves us 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.

Let's proceed to step 12:
If we divide 600 by 68, we get 8 and a remainder of 56.
The next digit of our result is 8. 
Result so far: 11722.897058
Subtract 544 from 600 to 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.

On to step 13:
If we divide 560 by 68, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 11722.8970588
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.

After the division, we end up with 11722.8970588 and a remainder of 1.6e-07.
