647215 divided by 68 
The aim is to understand the frequency of 68 in 647215.

Step 1:
6 divided by 68 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 68

Step 2:
If we divide 64 by 68, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 68

Advancing to step 3:
68 goes into 647 9 times with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 612 from 647 to get 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 68

On to step 4:
When dividing 352 by 68, we get 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 340 from 352 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 68

Let's proceed to step 5:
68 can be fit into 121 1 times, resulting in a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 951.0
If we take 68 away from 121, we end up with 53.
Take the next digit (5) from the dividend and append it to 53, then repeat: 535 / 68

Going ahead to step 6:
The number 68 fits into 535 7 times, leaving a remainder of 59.
Record the quotient 7 as the next digit in the result. 
Result so far: 9517.0
If we take 476 away from 535, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
If we divide 590 by 68, we get 8 and a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 9517.8
If we take 544 away from 590, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
68 can be fit into 460 6 times, resulting in a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 9517.86
If we subtract 408 from 460, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
68 can be fit into 520 7 times, resulting in a remainder of 44.
The next digit of our result is 7. 
Result so far: 9517.867
Deduct 476 from 520 and we're left 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.

Let's proceed to step 10:
440 divided by 68 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 9517.8676
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.

Let's proceed to step 11:
68 goes into 320 4 times with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 9517.86764
If we take 272 away from 320, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
If we divide 480 by 68, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 9517.867647
Subtract 476 from 480 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
If we divide 40 by 68, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 9517.867647
If we take 0 away from 40, we end up 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 14:
If we divide 400 by 68, we get 5 and a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 9517.86764705
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.

Our division results in 9517.86764705 with a remaining 6e-08.
