We look at the division of 133867 by 45 
The aim is to understand the frequency of 45 in 133867.

Advancing to step 1:
1 divided by 45 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 45

Let's proceed to step 2:
When dividing 13 by 45, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 45

Step 3:
The number 45 fits into 133 2 times, leaving a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 90 away from 133, we end up with 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 45

Advancing to step 4:
438 divided by 45 is 9 with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 33 after subtracting 405 from 438.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 45

Moving on to step 5:
If we divide 336 by 45, we get 7 and a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 297.0
If we subtract 315 from 336, we get 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 45

Advancing to step 6:
If we divide 217 by 45, we get 4 and a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 2974.0
Subtracting 180 from 217 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
45 can be fit into 370 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 2974.8
If we subtract 360 from 370, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
45 goes into 100 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2974.82
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
45 goes into 100 2 times with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 2974.822
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 2974.822, and the remainder is 0.001.
