297428 ÷ 68 
The aim is to understand the frequency of 68 in 297428.

Step 1:
68 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 68

Going ahead to step 2:
68 can be fit into 29 0 times, resulting in a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 68

Advancing to step 3:
297 divided by 68 is 4 with a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 272 from 297 to get 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 68

On to step 4:
254 divided by 68 is 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 204 away from 254, we end up with 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 68

Advancing to step 5:
If we divide 502 by 68, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 437.0
If we take 476 away from 502, we end up with 26.
Take the next digit (8) from the dividend and append it to 26, then repeat: 268 / 68

Step 6:
268 divided by 68 is 3 with a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 4373.0
Deduct 204 from 268 and we're left with 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 7:
If we divide 640 by 68, we get 9 and a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 4373.9
Subtracting 612 from 640 leaves us 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.

Going ahead to step 8:
The number 68 fits into 280 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 4373.94
If we subtract 272 from 280, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 68, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 4373.941
Subtract 68 from 80 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
68 goes into 120 1 times with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 4373.9411
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 4373.9411, with a leftover of 0.00052.
