We look at the division of 131990 by 67 
The aim is to understand the frequency of 67 in 131990.

Going ahead to 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
If we subtract 0 from 1, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 67

Let's proceed to step 2:
67 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 67

Step 3:
The number 67 fits into 131 1 times, leaving a remainder of 64.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 67 from 131 to get 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 67

Step 4:
If we divide 649 by 67, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 603 from 649, we get 46.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 67

On to step 5:
469 divided by 67 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 197.0
Subtract 469 from 469 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 67

Moving on to step 6:
67 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1970.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
67 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1970.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 67, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 1970.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 1970.0, and the remainder is 0.0.
