Let's divide 210602 by 68
The aim is to understand the frequency of 68 in 210602.

Let's proceed to step 1:
If we divide 2 by 68, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 68

Let's proceed to step 2:
When dividing 21 by 68, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 68

On to step 3:
When dividing 210 by 68, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 204 from 210 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 68

Let's proceed to step 4:
If we divide 66 by 68, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 68

Step 5:
The number 68 fits into 660 9 times, leaving a remainder of 48.
The next digit of our result is 9. 
Result so far: 309.0
If we take 612 away from 660, we end up with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 68

Step 6:
482 divided by 68 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 3097.0
Subtract 476 from 482 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 68, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 3097.0
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
The number 68 fits into 600 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 3097.08
Deduct 544 from 600 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
68 goes into 560 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3097.088
If we take 544 away from 560, we end up 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 3097.088 and a remainder of 0.0016.
