We look at the division of 561559 by 67 
The aim is to understand the frequency of 67 in 561559.

Step 1:
When dividing 5 by 67, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 67

Let's proceed to step 2:
67 goes into 56 0 times with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 67

Advancing to step 3:
When dividing 561 by 67, we get 8 with a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 536 from 561, we get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 67

Moving on to step 4:
67 can be fit into 255 3 times, resulting in a remainder of 54.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 201 from 255 leaves us with 54.
Fetch the next digit (5) from the dividend, attach it to 54 and continue: 545 / 67

Step 5:
If we divide 545 by 67, we get 8 and a remainder of 9.
The next digit of our result is 8. 
Result so far: 838.0
The remainder is 9 after subtracting 536 from 545.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 67

Let's proceed to step 6:
67 goes into 99 1 times with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 8381.0
The remainder is 32 after subtracting 67 from 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
If we divide 320 by 67, we get 4 and a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 8381.4
Subtracting 268 from 320 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.

Advancing to step 8:
67 goes into 520 7 times with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 8381.47
Subtracting 469 from 520 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
If we divide 510 by 67, we get 7 and a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 8381.477
Subtract 469 from 510 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

In conclusion, the division gives 8381.477 with a balance of 0.0041.
