We look at the division of 677688 by 67 
The aim is to understand the frequency of 67 in 677688.

Going ahead to step 1:
6 divided by 67 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 67

Moving on to step 2:
The number 67 fits into 67 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 67 away from 67, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 67

Advancing to step 3:
67 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 67

Step 4:
The number 67 fits into 76 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 67 from 76 leaves us with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 67

Step 5:
The number 67 fits into 98 1 times, leaving a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1011.0
If we take 67 away from 98, we end up with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 67

On to step 6:
The number 67 fits into 318 4 times, leaving a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 10114.0
Subtract 268 from 318 to 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 7:
The number 67 fits into 500 7 times, leaving a remainder of 31.
The next digit of our result is 7. 
Result so far: 10114.7
If we subtract 469 from 500, we 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 8:
When dividing 310 by 67, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 10114.74
If we take 268 away from 310, we end up 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.

Let's proceed to step 9:
420 divided by 67 is 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 10114.746
If we subtract 402 from 420, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
180 divided by 67 is 2 with a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 10114.7462
The remainder is 46 after subtracting 134 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
If we divide 460 by 67, we get 6 and a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 10114.74626
If we subtract 402 from 460, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
If we divide 580 by 67, we get 8 and a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 10114.746268
Deduct 536 from 580 and we're left 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.

Advancing to step 13:
67 goes into 440 6 times with a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 10114.7462686
Subtract 402 from 440 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
When dividing 380 by 67, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 10114.74626865
If we take 335 away from 380, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 10114.74626865 with a remainder of 4.5e-08.
