We're dividing 287940 by 67 
The aim is to understand the frequency of 67 in 287940.

Going ahead to step 1:
When dividing 2 by 67, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 67

On to step 2:
The number 67 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 67

Let's proceed to step 3:
The number 67 fits into 287 4 times, leaving a remainder of 19.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 268 from 287, we get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 67

On to step 4:
When dividing 199 by 67, we get 2 with a remainder of 65.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 134 from 199 and we're left with 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 67

Going ahead to step 5:
67 goes into 654 9 times with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 429.0
The remainder is 51 after subtracting 603 from 654.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 67

Let's proceed to step 6:
510 divided by 67 is 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 4297.0
Subtracting 469 from 510 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
67 goes into 410 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 4297.6
Subtracting 402 from 410 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
When dividing 80 by 67, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 4297.61
Subtracting 67 from 80 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
67 goes into 130 1 times with a remainder of 63.
The next digit of our result is 1. 
Result so far: 4297.611
If we subtract 67 from 130, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Our division results in 4297.611 with a remaining 0.0063.
