We look at the division of 428367 by 67 
The aim is to understand the frequency of 67 in 428367.

Advancing to step 1:
If we divide 4 by 67, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 67

Going ahead to step 2:
If we divide 42 by 67, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 67

Let's proceed to step 3:
The number 67 fits into 428 6 times, leaving a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 26 after subtracting 402 from 428.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 67

On to step 4:
When dividing 263 by 67, we get 3 with a remainder of 62.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtract 201 from 263 to get 62.
Fetch the next digit (6) from the dividend, attach it to 62 and continue: 626 / 67

Advancing to step 5:
The number 67 fits into 626 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 639.0
Subtract 603 from 626 to get 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 67

Let's proceed to step 6:
67 can be fit into 237 3 times, resulting in a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 6393.0
The remainder is 36 after subtracting 201 from 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 7:
The number 67 fits into 360 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6393.5
If we take 335 away from 360, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
67 goes into 250 3 times with a remainder of 49.
The next digit of our result is 3. 
Result so far: 6393.53
The remainder is 49 after subtracting 201 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 9:
67 goes into 490 7 times with a remainder of 21.
The next digit of our result is 7. 
Result so far: 6393.537
Subtract 469 from 490 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 10:
67 can be fit into 210 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 6393.5373
If we take 201 away from 210, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
The number 67 fits into 90 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 6393.53731
Subtracting 67 from 90 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
67 goes into 230 3 times with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 6393.537313
Deduct 201 from 230 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
290 divided by 67 is 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 6393.5373134
Subtracting 268 from 290 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
67 goes into 220 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 6393.53731343
If we take 201 away from 220, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 6393.53731343 and a remainder of 1.9e-08.
