We look at the division of 142536 by 67 
The aim is to understand the frequency of 67 in 142536.

Step 1:
The number 67 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 67

Step 2:
When dividing 14 by 67, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 67

Going ahead to step 3:
When dividing 142 by 67, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 134 from 142 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 67

Moving on to step 4:
85 divided by 67 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 67 from 85 and we're left with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 67

Let's proceed to step 5:
If we divide 183 by 67, we get 2 and a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 212.0
Subtract 134 from 183 to get 49.
Append the next digit (6) from the dividend to 49 and continue with: 496 / 67

Step 6:
67 can be fit into 496 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 2127.0
If we take 469 away from 496, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
When dividing 270 by 67, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 2127.4
Deduct 268 from 270 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
67 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2127.4
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 67 fits into 200 2 times, leaving a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 2127.402
If we take 134 away from 200, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
The number 67 fits into 660 9 times, leaving a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 2127.4029
Subtract 603 from 660 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 11:
If we divide 570 by 67, we get 8 and a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 2127.40298
If we take 536 away from 570, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
67 goes into 340 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2127.402985
Deduct 335 from 340 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
67 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 2127.402985
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
When dividing 500 by 67, we get 7 with a remainder of 31.
Put 7 as the next digit of the answer. 
Result so far: 2127.40298507
The remainder is 31 after subtracting 469 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 2127.40298507, with a leftover of 3.1e-08.
