We look at the division of 823901 by 67 
The aim is to understand the frequency of 67 in 823901.

Let's proceed to step 1:
The number 67 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 67

On to step 2:
67 can be fit into 82 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
If we take 67 away from 82, we end up with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 67

Step 3:
67 goes into 153 2 times with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 134 from 153 and we're left with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 67

Let's proceed 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: 122.0
If we subtract 134 from 199, we get 65.
Bring next digit (0) of the dividend behind the 65 and repeat the process: 650 / 67

On to step 5:
The number 67 fits into 650 9 times, leaving a remainder of 47.
The next digit of our result is 9. 
Result so far: 1229.0
Subtracting 603 from 650 leaves us with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 67

Let's proceed to step 6:
When dividing 471 by 67, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 12297.0
The remainder is 2 after subtracting 469 from 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 67 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 12297.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 67 is 2 with a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 12297.02
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.

Moving on to step 9:
67 can be fit into 660 9 times, resulting in a remainder of 57.
The next digit of our result is 9. 
Result so far: 12297.029
Deduct 603 from 660 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
When dividing 570 by 67, we get 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 12297.0298
Deduct 536 from 570 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
67 goes into 340 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12297.02985
If we subtract 335 from 340, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
67 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 12297.02985
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 13:
67 can be fit into 500 7 times, resulting in a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 12297.0298507
Subtracting 469 from 500 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
67 can be fit into 310 4 times, resulting in a remainder of 42.
The next digit of our result is 4. 
Result so far: 12297.02985074
Subtracting 268 from 310 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 12297.02985074 with a remainder of 4.2e-08.
