309588 ÷ 68 
The aim is to understand the frequency of 68 in 309588.

Let's proceed to step 1:
If we divide 3 by 68, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 68

Let's proceed to step 2:
68 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 68

Let's proceed to step 3:
If we divide 309 by 68, we get 4 and a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 272 from 309 to get 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 68

Going ahead to step 4:
When dividing 375 by 68, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 45.0
The remainder is 35 after subtracting 340 from 375.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 68

Let's proceed to step 5:
68 goes into 358 5 times with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 455.0
The remainder is 18 after subtracting 340 from 358.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 68

Going ahead to step 6:
68 goes into 188 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 4552.0
Subtract 136 from 188 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
520 divided by 68 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 4552.7
The remainder is 44 after subtracting 476 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
68 goes into 440 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 4552.76
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.

Advancing to step 9:
68 can be fit into 320 4 times, resulting in a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 4552.764
The remainder is 48 after subtracting 272 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
When dividing 480 by 68, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 4552.7647
If we subtract 476 from 480, we 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 11:
The number 68 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 4552.7647
The remainder is 40 after subtracting 0 from 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 12:
400 divided by 68 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4552.764705
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
68 can be fit into 600 8 times, resulting in a remainder of 56.
The next digit of our result is 8. 
Result so far: 4552.7647058
Subtract 544 from 600 to 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.

On to step 14:
When dividing 560 by 68, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 4552.76470588
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.

Our division results in 4552.76470588 with a remaining 1.6e-08.
