We look at the division of 298678 by 68 
The aim is to understand the frequency of 68 in 298678.

Advancing to step 1:
68 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 68

Let's proceed to step 2:
68 goes into 29 0 times with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 68

Step 3:
The number 68 fits into 298 4 times, leaving a remainder of 26.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 26 after subtracting 272 from 298.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 68

On to step 4:
266 divided by 68 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 204 from 266 and we're left with 62.
Include the next digit (7) from the dividend after 62, then repeat: 627 / 68

Step 5:
627 divided by 68 is 9 with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 439.0
If we take 612 away from 627, we end up with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 68

On to step 6:
The number 68 fits into 158 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 4392.0
Subtracting 136 from 158 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
68 goes into 220 3 times with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 4392.3
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
The number 68 fits into 160 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 4392.32
If we subtract 136 from 160, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
When dividing 240 by 68, we get 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 4392.323
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
68 goes into 360 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 4392.3235
Deduct 340 from 360 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
When dividing 200 by 68, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 4392.32352
Subtracting 136 from 200 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
68 goes into 640 9 times with a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 4392.323529
Subtracting 612 from 640 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
68 goes into 280 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4392.3235294
If we take 272 away from 280, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
When dividing 80 by 68, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 4392.32352941
Subtracting 68 from 80 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 4392.32352941 and a remainder of 1.2e-08.
