We look at the division of 287102 by 67 
The aim is to understand the frequency of 67 in 287102.

Going ahead to step 1:
2 divided by 67 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 67

Step 2:
67 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 67

Moving on to step 3:
The number 67 fits into 287 4 times, leaving a remainder of 19.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 268 from 287 to get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 67

Advancing to step 4:
If we divide 191 by 67, we get 2 and a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we take 134 away from 191, we end up with 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 67

Moving on to step 5:
67 can be fit into 570 8 times, resulting in a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 428.0
If we take 536 away from 570, we end up with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 67

Moving on to step 6:
67 goes into 342 5 times with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 4285.0
If we take 335 away from 342, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 67 fits into 70 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 4285.1
Subtract 67 from 70 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
The number 67 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 4285.1
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
When dividing 300 by 67, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 4285.104
If we take 268 away from 300, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
67 goes into 320 4 times with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 4285.1044
If we take 268 away from 320, we end up 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.

The final outcome is 4285.1044, with a leftover of 0.00052.
