640479 ÷ 67 
The aim is to understand the frequency of 67 in 640479.

Let's proceed to step 1:
The number 67 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 67

On to step 2:
If we divide 64 by 67, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (0) from the dividend to 64 and continue with: 640 / 67

On to step 3:
67 can be fit into 640 9 times, resulting in a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 603 from 640 and we're left with 37.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 67

Going ahead to step 4:
The number 67 fits into 374 5 times, leaving a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 95.0
The remainder is 39 after subtracting 335 from 374.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 67

Let's proceed to step 5:
When dividing 397 by 67, we get 5 with a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 955.0
Subtracting 335 from 397 leaves us with 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 67

On to step 6:
629 divided by 67 is 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 9559.0
The remainder is 26 after subtracting 603 from 629.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
260 divided by 67 is 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 9559.3
Subtracting 201 from 260 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 8:
590 divided by 67 is 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 9559.38
The remainder is 54 after subtracting 536 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
When dividing 540 by 67, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 9559.388
Subtract 536 from 540 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 9559.388 with a remaining 0.0004.
