239983 ÷ 68 
The aim is to understand the frequency of 68 in 239983.

Going ahead to step 1:
When dividing 2 by 68, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 68

Going ahead to step 2:
If we divide 23 by 68, we get 0 and a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 68

On to step 3:
68 goes into 239 3 times with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 204 from 239 and we're left with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 68

Going ahead to step 4:
When dividing 359 by 68, we get 5 with a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 340 away from 359, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 68

Going ahead to step 5:
If we divide 198 by 68, we get 2 and a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 352.0
If we subtract 136 from 198, we get 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 68

Advancing to step 6:
68 goes into 623 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 3529.0
Deduct 612 from 623 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
68 goes into 110 1 times with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 3529.1
Subtracting 68 from 110 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
68 can be fit into 420 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 3529.16
If we take 408 away from 420, we end up 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 goes into 120 1 times with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 3529.161
If we subtract 68 from 120, we 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.

Moving on to step 10:
68 can be fit into 520 7 times, resulting in a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 3529.1617
Subtracting 476 from 520 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.

Advancing to step 11:
68 can be fit into 440 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 3529.16176
Subtracting 408 from 440 leaves us 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.

Step 12:
The number 68 fits into 320 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 3529.161764
Subtract 272 from 320 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
68 can be fit into 480 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 3529.1617647
Deduct 476 from 480 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 14:
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: 3529.1617647
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 3529.1617647 with a remaining 4e-08.
