We look at the division of 586406 by 68 
The aim is to understand the frequency of 68 in 586406.

Advancing to step 1:
The number 68 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 68

Moving on to step 2:
When dividing 58 by 68, we get 0 with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Grab the next digit (6) from the dividend, add it to 58, then carry on: 586 / 68

Moving on to step 3:
68 goes into 586 8 times with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 42 after subtracting 544 from 586.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 68

Advancing to step 4:
68 goes into 424 6 times with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtracting 408 from 424 leaves us with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 68

On to step 5:
68 can be fit into 160 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 862.0
Subtract 136 from 160 to get 24.
Fetch the next digit (6) from the dividend, attach it to 24 and continue: 246 / 68

Let's proceed to step 6:
246 divided by 68 is 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 8623.0
The remainder is 42 after subtracting 204 from 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
The number 68 fits into 420 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 8623.6
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 68 is 1 with a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 8623.61
Deduct 68 from 120 and we're left 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.

Step 9:
68 can be fit into 520 7 times, resulting in a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 8623.617
If we subtract 476 from 520, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
When dividing 440 by 68, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 8623.6176
If we subtract 408 from 440, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
68 can be fit into 320 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 8623.61764
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.

Advancing to step 12:
The number 68 fits into 480 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 8623.617647
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.

Moving on to step 13:
When dividing 40 by 68, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8623.617647
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.

Let's proceed to step 14:
When dividing 400 by 68, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 8623.61764705
Deduct 340 from 400 and we're left 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.

After the division, we end up with 8623.61764705 and a remainder of 6e-08.
