We look at the division of 180341 by 45 
The aim is to understand the frequency of 45 in 180341.

Going ahead to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 45

Step 2:
45 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 45

Going ahead to step 3:
180 divided by 45 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 0 after subtracting 180 from 180.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 45

Advancing to step 4:
45 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 45

Going ahead to step 5:
45 can be fit into 34 0 times, resulting in a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 400.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 45

Moving on to step 6:
341 divided by 45 is 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 4007.0
If we take 315 away from 341, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
The number 45 fits into 260 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4007.5
Deduct 225 from 260 and we're left 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.

Moving on to step 8:
350 divided by 45 is 7 with a remainder of 35.
The next digit of our result is 7. 
Result so far: 4007.57
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
When dividing 350 by 45, we get 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 4007.577
Deduct 315 from 350 and we're left 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.

The final outcome is 4007.577, with a leftover of 0.0035.
