We look at the division of 19222021 by 68 
The aim is to understand the frequency of 68 in 19222021.

Advancing to step 1:
68 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 68

Going ahead to step 2:
68 goes into 19 0 times with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 68

Going ahead to step 3:
68 goes into 192 2 times with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 56 after subtracting 136 from 192.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 68

On to step 4:
If we divide 562 by 68, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 544 from 562 and we're left with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 68

Advancing to step 5:
182 divided by 68 is 2 with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 282.0
Deduct 136 from 182 and we're left with 46.
Fetch the next digit (0) from the dividend, attach it to 46 and continue: 460 / 68

Let's proceed to step 6:
68 can be fit into 460 6 times, resulting in a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 2826.0
If we subtract 408 from 460, we get 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 68

Going ahead to step 7:
If we divide 522 by 68, we get 7 and a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 28267.0
Deduct 476 from 522 and we're left with 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 68

Going ahead to step 8:
The number 68 fits into 461 6 times, leaving a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 282676.0
Subtracting 408 from 461 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
68 can be fit into 530 7 times, resulting in a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 282676.7
If we take 476 away from 530, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 10:
If we divide 540 by 68, we get 7 and a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 282676.77
The remainder is 64 after subtracting 476 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 282676.77, with a leftover of 0.064.
