Let's divide 663908 by 67
The aim is to understand the frequency of 67 in 663908.

Step 1:
The number 67 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 67

Let's proceed to step 2:
If we divide 66 by 67, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 67

Moving on to step 3:
When dividing 663 by 67, we get 9 with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 603 from 663 to get 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 67

Going ahead to step 4:
If we divide 609 by 67, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Deduct 603 from 609 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 67

On to step 5:
60 divided by 67 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 990.0
If we subtract 0 from 60, we get 60.
Take the next digit (8) from the dividend and append it to 60, then repeat: 608 / 67

Going ahead to step 6:
When dividing 608 by 67, we get 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 9909.0
Deduct 603 from 608 and we're left 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.

Advancing to step 7:
When dividing 50 by 67, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 9909.0
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.

Moving on to step 8:
When dividing 500 by 67, we get 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 9909.07
Subtract 469 from 500 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
67 goes into 310 4 times with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 9909.074
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.

Step 10:
The number 67 fits into 420 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 9909.0746
If we take 402 away from 420, we end up 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.

Step 11:
The number 67 fits into 180 2 times, leaving a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 9909.07462
If we take 134 away from 180, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
67 goes into 460 6 times with a remainder of 58.
The next digit of our result is 6. 
Result so far: 9909.074626
The remainder is 58 after subtracting 402 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 13:
When dividing 580 by 67, we get 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 9909.0746268
Subtracting 536 from 580 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
67 goes into 440 6 times with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 9909.07462686
Deduct 402 from 440 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 9909.07462686 with a remainder of 3.8e-08.
