We're dividing 286531 by 67 
The aim is to understand the frequency of 67 in 286531.

On to step 1:
2 divided by 67 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 67

Going ahead to step 2:
If we divide 28 by 67, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 67

Let's proceed to step 3:
If we divide 286 by 67, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 268 from 286 leaves us with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 67

Moving on to step 4:
If we divide 185 by 67, we get 2 and a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 51 after subtracting 134 from 185.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 67

Moving on to step 5:
The number 67 fits into 513 7 times, leaving a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 427.0
Subtract 469 from 513 to get 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 67

On to step 6:
If we divide 441 by 67, we get 6 and a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 4276.0
Deduct 402 from 441 and we're left 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.

Let's proceed to step 7:
The number 67 fits into 390 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 4276.5
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.

On to step 8:
67 goes into 550 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 4276.58
If we take 536 away from 550, we end up 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.

On to step 9:
If we divide 140 by 67, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 4276.582
If we subtract 134 from 140, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
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: 4276.582
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
600 divided by 67 is 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 4276.58208
Subtracting 536 from 600 leaves us 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.

Step 12:
The number 67 fits into 640 9 times, leaving a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 4276.582089
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.

Let's proceed to step 13:
67 goes into 370 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4276.5820895
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 14:
The number 67 fits into 350 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 4276.58208955
The remainder is 15 after subtracting 335 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 4276.58208955 with a balance of 1.5e-08.
