138320 divided by 68 
The aim is to understand the frequency of 68 in 138320.

Going ahead to step 1:
68 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 68

Going ahead to step 2:
13 divided by 68 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 68

Going ahead to step 3:
If we divide 138 by 68, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 136 from 138 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 68

Let's proceed to step 4:
If we divide 23 by 68, we get 0 and a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 23, we get 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 68

Step 5:
When dividing 232 by 68, we get 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
Deduct 204 from 232 and we're left with 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 68

Step 6:
68 goes into 280 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 2034.0
Subtract 272 from 280 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 68, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 2034.1
The remainder is 12 after subtracting 68 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
68 goes into 120 1 times with a remainder of 52.
The next digit of our result is 1. 
Result so far: 2034.11
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.

The quotient of the division is 2034.11, and the remainder is 0.052.
