We look at the division of 641903 by 67 
The aim is to understand the frequency of 67 in 641903.

Step 1:
The number 67 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 67

Going ahead to step 2:
If we divide 64 by 67, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 67

Let's proceed to step 3:
When dividing 641 by 67, we get 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 38 after subtracting 603 from 641.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 67

On to step 4:
389 divided by 67 is 5 with a remainder of 54.
The next digit of our result is 5. 
Result so far: 95.0
Deduct 335 from 389 and we're left with 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 67

On to step 5:
67 can be fit into 540 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 958.0
The remainder is 4 after subtracting 536 from 540.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 67

Going ahead to step 6:
43 divided by 67 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 9580.0
Subtract 0 from 43 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
430 divided by 67 is 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 9580.6
The remainder is 28 after subtracting 402 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
67 can be fit into 280 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 9580.64
Subtracting 268 from 280 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 67, we get 1 and a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 9580.641
Deduct 67 from 120 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 10:
67 goes into 530 7 times with a remainder of 61.
The next digit of our result is 7. 
Result so far: 9580.6417
Subtract 469 from 530 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 11:
610 divided by 67 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 9580.64179
The remainder is 7 after subtracting 603 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
67 can be fit into 70 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 9580.641791
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.

Advancing to step 13:
When dividing 30 by 67, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9580.641791
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
67 goes into 300 4 times with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 9580.64179104
Subtract 268 from 300 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 9580.64179104 with a balance of 3.2e-08.
