306222 ÷ 68 
The aim is to understand the frequency of 68 in 306222.

On to step 1:
When dividing 3 by 68, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 68

Going ahead to step 2:
30 divided by 68 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 68

On to step 3:
The number 68 fits into 306 4 times, leaving a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 272 from 306 leaves us with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 68

On to step 4:
When dividing 342 by 68, we get 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 340 from 342 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 68

On to step 5:
If we divide 22 by 68, we get 0 and a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 450.0
Subtract 0 from 22 to get 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 68

Moving on to step 6:
If we divide 222 by 68, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 4503.0
Subtract 204 from 222 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
When dividing 180 by 68, we get 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 4503.2
If we take 136 away from 180, we end up 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 8:
The number 68 fits into 440 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 4503.26
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.

Advancing to step 9:
68 can be fit into 320 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 4503.264
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.

Step 10:
68 can be fit into 480 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 4503.2647
Subtracting 476 from 480 leaves us 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.

Going ahead to step 11:
40 divided by 68 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4503.2647
Deduct 0 from 40 and we're left with 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:
If we divide 400 by 68, we get 5 and a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 4503.264705
If we take 340 away from 400, we end up with 60.
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:
When dividing 600 by 68, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 4503.2647058
The remainder is 56 after subtracting 544 from 600.
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:
The number 68 fits into 560 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 4503.26470588
Deduct 544 from 560 and we're left 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.

After the division, we end up with 4503.26470588 and a remainder of 1.6e-08.
