We look at the division of 810879 by 67 
The aim is to understand the frequency of 67 in 810879.

Moving on to step 1:
67 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 67

Let's proceed to step 2:
81 divided by 67 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 67 from 81 and we're left with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 67

Going ahead to step 3:
67 goes into 140 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 134 from 140 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 67

Moving on to step 4:
68 divided by 67 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
The remainder is 1 after subtracting 67 from 68.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 67

Moving on to step 5:
67 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 1210.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 67

Advancing to step 6:
67 can be fit into 179 2 times, resulting in a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 12102.0
If we take 134 away from 179, 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.

Moving on to step 7:
67 can be fit into 450 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 12102.6
Subtracting 402 from 450 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
If we divide 480 by 67, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 12102.67
The remainder is 11 after subtracting 469 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
When dividing 110 by 67, we get 1 with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 12102.671
If we take 67 away from 110, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
The number 67 fits into 430 6 times, leaving a remainder of 28.
The next digit of our result is 6. 
Result so far: 12102.6716
Subtract 402 from 430 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
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: 12102.67164
Subtract 268 from 280 to get 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 12:
67 can be fit into 120 1 times, resulting in a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 12102.671641
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.

Advancing to step 13:
The number 67 fits into 530 7 times, leaving a remainder of 61.
The next digit of our result is 7. 
Result so far: 12102.6716417
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 14:
If we divide 610 by 67, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 12102.67164179
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.

Our division results in 12102.67164179 with a remaining 7e-09.
