We're dividing 4270 by 68 
The aim is to understand the frequency of 68 in 4270.

Advancing to step 1:
4 divided by 68 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 68

Going ahead to step 2:
The number 68 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 68

Moving on to step 3:
427 divided by 68 is 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 408 from 427 to get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 68

Advancing to step 4:
When dividing 190 by 68, we get 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Subtract 136 from 190 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 5:
68 can be fit into 540 7 times, resulting in a remainder of 64.
The next digit of our result is 7. 
Result so far: 62.7
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.

Advancing to step 6:
The number 68 fits into 640 9 times, leaving a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 62.79
Deduct 612 from 640 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.

Step 7:
The number 68 fits into 280 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 62.794
Subtracting 272 from 280 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
68 can be fit into 80 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 62.7941
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
68 can be fit into 120 1 times, resulting in a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 62.79411
Subtracting 68 from 120 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 62.79411, with a leftover of 5.2e-05.
