838198 divided by 68 
The aim is to understand the frequency of 68 in 838198.

Moving on to step 1:
The number 68 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 68

Step 2:
If we divide 83 by 68, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 68 away from 83, we end up with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 68

Advancing to step 3:
68 can be fit into 158 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 136 from 158 to get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 68

On to step 4:
The number 68 fits into 221 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we take 204 away from 221, we end up with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 68

Moving on to step 5:
When dividing 179 by 68, we get 2 with a remainder of 43.
The number 2 becomes the next digit in our result. 
Result so far: 1232.0
Subtract 136 from 179 to get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 68

On to step 6:
When dividing 438 by 68, we get 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 12326.0
If we subtract 408 from 438, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
68 can be fit into 300 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 12326.4
Deduct 272 from 300 and we're left 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.

Let's proceed to step 8:
If we divide 280 by 68, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 12326.44
Subtract 272 from 280 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 12326.44 with a remainder of 0.008.
