We're dividing 7821307 by 180 
The aim is to understand the frequency of 180 in 7821307.

Step 1:
180 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 180

Step 2:
180 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 180

Moving on to step 3:
When dividing 782 by 180, we get 4 with a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 720 from 782 and we're left with 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 180

Step 4:
180 goes into 621 3 times with a remainder of 81.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 81 after subtracting 540 from 621.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 180

Let's proceed to step 5:
The number 180 fits into 813 4 times, leaving a remainder of 93.
Record the quotient 4 as the next digit in the result. 
Result so far: 434.0
Subtract 720 from 813 to get 93.
Include the next digit (0) from the dividend after 93, then repeat: 930 / 180

Advancing to step 6:
When dividing 930 by 180, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 4345.0
The remainder is 30 after subtracting 900 from 930.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 180

Step 7:
307 divided by 180 is 1 with a remainder of 127.
Write down 1 as next digit of the result. 
Result so far: 43451.0
The remainder is 127 after subtracting 180 from 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 8:
The number 180 fits into 1270 7 times, leaving a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 43451.7
If we subtract 1260 from 1270, 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.

Let's proceed to step 9:
100 divided by 180 is 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 43451.7
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
180 goes into 1000 5 times with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 43451.705
Subtracting 900 from 1000 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
When dividing 1000 by 180, we get 5 with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 43451.7055
Subtract 900 from 1000 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 43451.7055 with a remainder of 0.001.
