We look at the division of 670881 by 67 
The aim is to understand the frequency of 67 in 670881.

Let's proceed to step 1:
6 divided by 67 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 67

Going ahead to step 2:
67 divided by 67 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 67 from 67 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 67

Let's proceed to step 3:
The number 67 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 67

On to step 4:
When dividing 8 by 67, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 67

Step 5:
When dividing 88 by 67, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1001.0
Subtract 67 from 88 to get 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 67

Moving on to step 6:
When dividing 211 by 67, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 10013.0
The remainder is 10 after subtracting 201 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 67, we get 1 and a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 10013.1
The remainder is 33 after subtracting 67 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 8:
The number 67 fits into 330 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 10013.14
Subtract 268 from 330 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
67 goes into 620 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 10013.149
If we take 603 away from 620, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 10:
67 can be fit into 170 2 times, resulting in a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 10013.1492
The remainder is 36 after subtracting 134 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
If we divide 360 by 67, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 10013.14925
Deduct 335 from 360 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
When dividing 250 by 67, we get 3 with a remainder of 49.
The next digit of our result is 3. 
Result so far: 10013.149253
If we subtract 201 from 250, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 13:
If we divide 490 by 67, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 10013.1492537
If we subtract 469 from 490, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
The number 67 fits into 210 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 10013.14925373
Subtract 201 from 210 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final outcome is 10013.14925373, with a leftover of 9e-09.
