We look at the division of 421852 by 67 
The aim is to understand the frequency of 67 in 421852.

Advancing to step 1:
The number 67 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 67

Step 2:
When dividing 42 by 67, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 67

Let's proceed to step 3:
421 divided by 67 is 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 402 away from 421, we end up with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 67

Let's proceed to step 4:
When dividing 198 by 67, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we subtract 134 from 198, we get 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 67

Going ahead to step 5:
645 divided by 67 is 9 with a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 629.0
The remainder is 42 after subtracting 603 from 645.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 67

Step 6:
The number 67 fits into 422 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 6296.0
If we take 402 away from 422, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
When dividing 200 by 67, we get 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 6296.2
Subtract 134 from 200 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
If we divide 660 by 67, we get 9 and a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 6296.29
The remainder is 57 after subtracting 603 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
570 divided by 67 is 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 6296.298
If we subtract 536 from 570, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
67 goes into 340 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 6296.2985
If we take 335 away from 340, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
If we divide 50 by 67, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6296.2985
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 12:
500 divided by 67 is 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 6296.298507
The remainder is 31 after subtracting 469 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 13:
When dividing 310 by 67, we get 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 6296.2985074
Subtract 268 from 310 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
The number 67 fits into 420 6 times, leaving a remainder of 18.
The next digit of our result is 6. 
Result so far: 6296.29850746
Subtracting 402 from 420 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 6296.29850746, and the remainder is 1.8e-08.
