490184 ÷ 68 
The aim is to understand the frequency of 68 in 490184.

Advancing to step 1:
When dividing 4 by 68, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 68

Advancing to step 2:
49 divided by 68 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 68

Going ahead to step 3:
If we divide 490 by 68, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 476 from 490 and we're left with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 68

Going ahead to step 4:
If we divide 141 by 68, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 72.0
Deduct 136 from 141 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 68

Advancing to step 5:
58 divided by 68 is 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 720.0
If we subtract 0 from 58, we get 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 68

Going ahead to step 6:
68 goes into 584 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 7208.0
Subtracting 544 from 584 leaves us 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.

Going ahead to step 7:
68 goes into 400 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 7208.5
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.

Going ahead to step 8:
When dividing 600 by 68, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 7208.58
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.

Advancing to step 9:
68 can be fit into 560 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7208.588
Subtract 544 from 560 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 7208.588 with a remainder of 0.0016.
