We look at the division of 559573 by 67 
The aim is to understand the frequency of 67 in 559573.

Going ahead to step 1:
67 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 67

Let's proceed to step 2:
55 divided by 67 is 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Append the next digit (9) from the dividend to 55 and continue with: 559 / 67

On to step 3:
559 divided by 67 is 8 with a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 23 after subtracting 536 from 559.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 67

Moving on to step 4:
If we divide 235 by 67, we get 3 and a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 83.0
The remainder is 34 after subtracting 201 from 235.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 67

On to step 5:
347 divided by 67 is 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 835.0
If we subtract 335 from 347, we get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 67

Advancing to step 6:
The number 67 fits into 123 1 times, leaving a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 8351.0
Deduct 67 from 123 and we're left 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 7:
If we divide 560 by 67, we get 8 and a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 8351.8
The remainder is 24 after subtracting 536 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
The number 67 fits into 240 3 times, leaving a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 8351.83
The remainder is 39 after subtracting 201 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 9:
390 divided by 67 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 8351.835
If we subtract 335 from 390, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
67 can be fit into 550 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 8351.8358
The remainder is 14 after subtracting 536 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
When dividing 140 by 67, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 8351.83582
If we subtract 134 from 140, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
When dividing 60 by 67, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 8351.83582
Subtract 0 from 60 to 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.

Let's proceed to step 13:
When dividing 600 by 67, we get 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 8351.8358208
If we subtract 536 from 600, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
67 goes into 640 9 times with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 8351.83582089
If we take 603 away from 640, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 8351.83582089 with a remaining 3.7e-08.
