We're dividing 312878 by 67 
The aim is to understand the frequency of 67 in 312878.

Advancing to step 1:
If we divide 3 by 67, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 67

Let's proceed to step 2:
If we divide 31 by 67, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 67

Moving on to step 3:
312 divided by 67 is 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 268 away from 312, we end up with 44.
Grab the next digit (8) from the dividend, add it to 44, then carry on: 448 / 67

Moving on to step 4:
67 goes into 448 6 times with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtract 402 from 448 to get 46.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 67

Step 5:
If we divide 467 by 67, we get 6 and a remainder of 65.
Record the quotient 6 as the next digit in the result. 
Result so far: 466.0
If we subtract 402 from 467, we get 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 67

Let's proceed to step 6:
When dividing 658 by 67, we get 9 with a remainder of 55.
Write down 9 as next digit of the result. 
Result so far: 4669.0
Subtracting 603 from 658 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
The number 67 fits into 550 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 4669.8
Subtracting 536 from 550 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
67 goes into 140 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 4669.82
If we take 134 away from 140, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
If we divide 60 by 67, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 4669.82
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 10:
67 goes into 600 8 times with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 4669.8208
Deduct 536 from 600 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
If we divide 640 by 67, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 4669.82089
If we subtract 603 from 640, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
If we divide 370 by 67, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 4669.820895
Subtracting 335 from 370 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
350 divided by 67 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 4669.8208955
If we subtract 335 from 350, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 4669.8208955 with a remaining 1.5e-07.
