We're dividing 478643 by 68 
The aim is to understand the frequency of 68 in 478643.

Advancing to step 1:
4 divided by 68 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 68

Let's proceed to step 2:
The number 68 fits into 47 0 times, leaving a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Append the next digit (8) from the dividend to 47 and continue with: 478 / 68

Let's proceed to step 3:
478 divided by 68 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 476 from 478, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 68

Moving on to step 4:
68 can be fit into 26 0 times, resulting in a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
The remainder is 26 after subtracting 0 from 26.
Include the next digit (4) from the dividend after 26, then repeat: 264 / 68

On to step 5:
68 goes into 264 3 times with a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 703.0
Subtracting 204 from 264 leaves us with 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 68

On to step 6:
The number 68 fits into 603 8 times, leaving a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 7038.0
Deduct 544 from 603 and we're left 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.

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: 7038.8
If we subtract 544 from 590, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
When dividing 460 by 68, we get 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 7038.86
Subtract 408 from 460 to 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.
Write down 7 as next digit of the result. 
Result so far: 7038.867
Subtract 476 from 520 to 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.

Step 10:
If we divide 440 by 68, we get 6 and a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 7038.8676
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
320 divided by 68 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 7038.86764
Subtracting 272 from 320 leaves us 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.

Advancing to step 12:
The number 68 fits into 480 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7038.867647
If we subtract 476 from 480, we 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: 7038.867647
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.

Advancing to step 14:
The number 68 fits into 400 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 7038.86764705
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.

The final result is 7038.86764705 with a remainder of 6e-08.
