We look at the division of 553660 by 67 
The aim is to understand the frequency of 67 in 553660.

On to step 1:
When dividing 5 by 67, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 67

Let's proceed to step 2:
If we divide 55 by 67, we get 0 and a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 67

Going ahead to step 3:
The number 67 fits into 553 8 times, leaving a remainder of 17.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 536 from 553, we get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 67

Advancing to step 4:
176 divided by 67 is 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
If we subtract 134 from 176, we get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 67

Let's proceed to step 5:
If we divide 426 by 67, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 826.0
Subtract 402 from 426 to get 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 67

Moving on to step 6:
67 can be fit into 240 3 times, resulting in a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 8263.0
If we subtract 201 from 240, we get 39.
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 7:
When dividing 390 by 67, we get 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 8263.5
Subtract 335 from 390 to 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.

On to step 8:
67 goes into 550 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 8263.58
If we take 536 away from 550, we end up with 14.
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 9:
When dividing 140 by 67, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 8263.582
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.

Advancing to step 10:
When dividing 60 by 67, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 8263.582
Deduct 0 from 60 and we're left with 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 11:
If we divide 600 by 67, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 8263.58208
Subtracting 536 from 600 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
The number 67 fits into 640 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 8263.582089
Subtracting 603 from 640 leaves us 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.

On to step 13:
67 can be fit into 370 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 8263.5820895
Subtract 335 from 370 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
67 goes into 350 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8263.58208955
The remainder is 15 after subtracting 335 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 8263.58208955 with a remaining 1.5e-08.
