809213 divided by 68 
The aim is to understand the frequency of 68 in 809213.

On to step 1:
68 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 68

Step 2:
When dividing 80 by 68, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 68 from 80, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 68

Let's proceed to step 3:
68 goes into 129 1 times with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 68 from 129, we get 61.
Append the next digit (2) from the dividend to 61 and continue with: 612 / 68

Step 4:
68 can be fit into 612 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
If we take 612 away from 612, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 68

Let's proceed to step 5:
If we divide 1 by 68, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 1190.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 68

Moving on to step 6:
When dividing 13 by 68, we get 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 11900.0
The remainder is 13 after subtracting 0 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
130 divided by 68 is 1 with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 11900.1
Subtract 68 from 130 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 8:
68 goes into 620 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 11900.19
The remainder is 8 after subtracting 612 from 620.
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 9:
The number 68 fits into 80 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 11900.191
If we take 68 away from 80, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
When dividing 120 by 68, we get 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 11900.1911
Subtracting 68 from 120 leaves us 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.

Our division results in 11900.1911 with a remaining 0.00052.
