We divide 86415717 by 180
The aim is to understand the frequency of 180 in 86415717.

Moving on to step 1:
When dividing 8 by 180, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 180

Moving on to step 2:
When dividing 86 by 180, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 180

Let's proceed to step 3:
180 goes into 864 4 times with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 720 from 864 leaves us with 144.
Include the next digit (1) from the dividend after 144, then repeat: 1441 / 180

Going ahead to step 4:
If we divide 1441 by 180, we get 8 and a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 1440 away from 1441, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 180

Moving on to step 5:
180 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 480.0
Subtract 0 from 15 to get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 180

On to step 6:
If we divide 157 by 180, we get 0 and a remainder of 157.
The number 0 becomes the next digit in our result. 
Result so far: 4800.0
If we subtract 0 from 157, we get 157.
Bring next digit (1) of the dividend behind the 157 and repeat the process: 1571 / 180

On to step 7:
180 goes into 1571 8 times with a remainder of 131.
Use 8 as the next digit of our solution. 
Result so far: 48008.0
The remainder is 131 after subtracting 1440 from 1571.
Grab the next digit (7) from the dividend, add it to 131, then carry on: 1317 / 180

On to step 8:
180 goes into 1317 7 times with a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 480087.0
Subtracting 1260 from 1317 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 9:
If we divide 570 by 180, we get 3 and a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 480087.3
Subtracting 540 from 570 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 180, we get 1 and a remainder of 120.
The number 1 becomes the next digit in our result. 
Result so far: 480087.31
Subtract 180 from 300 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
When dividing 1200 by 180, we get 6 with a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 480087.316
If we take 1080 away from 1200, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
180 goes into 1200 6 times with a remainder of 120.
The next digit of our result is 6. 
Result so far: 480087.3166
If we subtract 1080 from 1200, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final result is 480087.3166 with a remainder of 0.0012.
