We look at the division of 333529 by 68 
The aim is to understand the frequency of 68 in 333529.

On to step 1:
The number 68 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 68

Moving on to step 2:
When dividing 33 by 68, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 68

On to step 3:
333 divided by 68 is 4 with a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 272 away from 333, we end up with 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 68

Advancing to step 4:
615 divided by 68 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 612 from 615, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 68

Let's proceed to step 5:
68 can be fit into 32 0 times, resulting in a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 490.0
The remainder is 32 after subtracting 0 from 32.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 68

Moving on to step 6:
329 divided by 68 is 4 with a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 4904.0
If we take 272 away from 329, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
68 goes into 570 8 times with a remainder of 26.
The next digit of our result is 8. 
Result so far: 4904.8
If we take 544 away from 570, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
The number 68 fits into 260 3 times, leaving a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 4904.83
Subtracting 204 from 260 leaves us 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.

Moving on to step 9:
If we divide 560 by 68, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 4904.838
Subtracting 544 from 560 leaves us 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.

Let's proceed to step 10:
If we divide 160 by 68, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 4904.8382
Deduct 136 from 160 and we're left with 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 11:
The number 68 fits into 240 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 4904.83823
Subtracting 204 from 240 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
68 goes into 360 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 4904.838235
If we take 340 away from 360, we end up 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.

On to step 13:
When dividing 200 by 68, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 4904.8382352
Subtract 136 from 200 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
68 can be fit into 640 9 times, resulting in a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 4904.83823529
The remainder is 28 after subtracting 612 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 4904.83823529, with a leftover of 2.8e-08.
