We look at the division of 212291 by 68 
The aim is to understand the frequency of 68 in 212291.

Advancing to step 1:
The number 68 fits into 2 0 times, leaving 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

Step 2:
21 divided by 68 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 68

Moving on to step 3:
If we divide 212 by 68, we get 3 and a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 204 from 212 and we're left with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 68

Moving on to step 4:
68 goes into 82 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 68 from 82 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 68

Moving on to step 5:
68 goes into 149 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 312.0
Deduct 136 from 149 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 68

Moving on to step 6:
If we divide 131 by 68, we get 1 and a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 3121.0
If we subtract 68 from 131, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
68 goes into 630 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 3121.9
Subtracting 612 from 630 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
68 goes into 180 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 3121.92
Subtracting 136 from 180 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 9:
68 can be fit into 440 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 3121.926
If we take 408 away from 440, we end up with 32.
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 10:
68 goes into 320 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 3121.9264
Subtracting 272 from 320 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
68 can be fit into 480 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 3121.92647
Subtract 476 from 480 to 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 12:
If we divide 40 by 68, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3121.92647
Deduct 0 from 40 and we're left 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 13:
400 divided by 68 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 3121.9264705
If we take 340 away from 400, we end up 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.

Moving on to step 14:
The number 68 fits into 600 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 3121.92647058
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.

The quotient of the division is 3121.92647058, and the remainder is 5.6e-08.
