638045 ÷ 68 
The aim is to understand the frequency of 68 in 638045.

Advancing to step 1:
68 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 68

Moving on to step 2:
63 divided by 68 is 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 68

Let's proceed to step 3:
If we divide 638 by 68, we get 9 and a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 612 away from 638, we end up with 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 68

Moving on to step 4:
68 can be fit into 260 3 times, resulting in a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 93.0
Subtract 204 from 260 to get 56.
Take the next digit (4) from the dividend and append it to 56, then repeat: 564 / 68

Advancing to step 5:
564 divided by 68 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 938.0
If we take 544 away from 564, we end up with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 68

Let's proceed to step 6:
68 can be fit into 205 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 9383.0
If we subtract 204 from 205, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 68 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9383.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
68 can be fit into 100 1 times, resulting in a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 9383.01
The remainder is 32 after subtracting 68 from 100.
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 9:
320 divided by 68 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 9383.014
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.

Step 10:
68 goes into 480 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 9383.0147
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.

Let's proceed to step 11:
40 divided by 68 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 9383.0147
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 12:
The number 68 fits into 400 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 9383.014705
If we subtract 340 from 400, we get 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 13:
600 divided by 68 is 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 9383.0147058
If we take 544 away from 600, 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.

Moving on to step 14:
When dividing 560 by 68, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 9383.01470588
If we take 544 away from 560, we end up 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.

The quotient of the division is 9383.01470588, and the remainder is 1.6e-08.
