We divide 81547430 by 180
The aim is to understand the frequency of 180 in 81547430.

Step 1:
When dividing 8 by 180, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 180

Moving on to step 2:
When dividing 81 by 180, we get 0 with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 180

On to step 3:
815 divided by 180 is 4 with a remainder of 95.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 720 from 815 to get 95.
Append the next digit (4) from the dividend to 95 and continue with: 954 / 180

On to step 4:
180 goes into 954 5 times with a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Deduct 900 from 954 and we're left with 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 180

Step 5:
547 divided by 180 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 453.0
Deduct 540 from 547 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 180

Moving on to step 6:
180 goes into 74 0 times with a remainder of 74.
The next digit of our result is 0. 
Result so far: 4530.0
Subtract 0 from 74 to get 74.
Fetch the next digit (3) from the dividend, attach it to 74 and continue: 743 / 180

On to step 7:
743 divided by 180 is 4 with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 45304.0
If we take 720 away from 743, we end up with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 180

Let's proceed to step 8:
When dividing 230 by 180, we get 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 453041.0
The remainder is 50 after subtracting 180 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
180 can be fit into 500 2 times, resulting in a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 453041.2
Subtract 360 from 500 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
1400 divided by 180 is 7 with a remainder of 140.
The next digit of our result is 7. 
Result so far: 453041.27
Subtracting 1260 from 1400 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
180 goes into 1400 7 times with a remainder of 140.
Put 7 as the next digit of the answer. 
Result so far: 453041.277
Deduct 1260 from 1400 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The quotient of the division is 453041.277, and the remainder is 0.014.
