We look at the division of 381671 by 67 
The aim is to understand the frequency of 67 in 381671.

Advancing to step 1:
67 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 67

Going ahead to step 2:
When dividing 38 by 67, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 67

On to step 3:
If we divide 381 by 67, we get 5 and a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 335 from 381 and we're left with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 67

Moving on to step 4:
67 can be fit into 466 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 56.0
Deduct 402 from 466 and we're left with 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 67

Let's proceed to step 5:
647 divided by 67 is 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 569.0
If we subtract 603 from 647, we get 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 67

Going ahead to step 6:
441 divided by 67 is 6 with a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 5696.0
If we take 402 away from 441, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
67 goes into 390 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 5696.5
Subtracting 335 from 390 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 8:
67 can be fit into 550 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 5696.58
The remainder is 14 after subtracting 536 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
140 divided by 67 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 5696.582
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.

Advancing to step 10:
The number 67 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 5696.582
Deduct 0 from 60 and we're left 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.

Moving on to step 11:
67 can be fit into 600 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 5696.58208
Subtract 536 from 600 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
If we divide 640 by 67, we get 9 and a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 5696.582089
The remainder is 37 after subtracting 603 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 13:
67 can be fit into 370 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5696.5820895
If we subtract 335 from 370, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
If we divide 350 by 67, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 5696.58208955
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.

The final outcome is 5696.58208955, with a leftover of 1.5e-08.
