507268 ÷ 68 
The aim is to understand the frequency of 68 in 507268.

Let's proceed to step 1:
5 divided by 68 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 68

Moving on to step 2:
50 divided by 68 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 68

Step 3:
507 divided by 68 is 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 476 from 507 to get 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 68

On to step 4:
68 goes into 312 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 74.0
The remainder is 40 after subtracting 272 from 312.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 68

Let's proceed to step 5:
406 divided by 68 is 5 with a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 745.0
Deduct 340 from 406 and we're left with 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 68

Advancing to step 6:
68 can be fit into 668 9 times, resulting in a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 7459.0
If we take 612 away from 668, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
If we divide 560 by 68, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7459.8
Subtracting 544 from 560 leaves us 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.

On to step 8:
If we divide 160 by 68, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 7459.82
The remainder is 24 after subtracting 136 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 68 fits into 240 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 7459.823
The remainder is 36 after subtracting 204 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
68 can be fit into 360 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 7459.8235
If we subtract 340 from 360, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
200 divided by 68 is 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 7459.82352
If we subtract 136 from 200, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
640 divided by 68 is 9 with a remainder of 28.
The next digit of our result is 9. 
Result so far: 7459.823529
The remainder is 28 after subtracting 612 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
280 divided by 68 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 7459.8235294
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.

Advancing to step 14:
68 goes into 80 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 7459.82352941
If we subtract 68 from 80, we 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.

The quotient of the division is 7459.82352941, and the remainder is 1.2e-08.
