We're dividing 14221522 by 180 
The aim is to understand the frequency of 180 in 14221522.

On to step 1:
The number 180 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 180

Moving on to step 2:
The number 180 fits into 14 0 times, leaving a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 180

Advancing to step 3:
If we divide 142 by 180, we get 0 and a remainder of 142.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 142 after subtracting 0 from 142.
Include the next digit (2) from the dividend after 142, then repeat: 1422 / 180

Going ahead to step 4:
If we divide 1422 by 180, we get 7 and a remainder of 162.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 1260 from 1422 leaves us with 162.
Bring next digit (1) of the dividend behind the 162 and repeat the process: 1621 / 180

Moving on to step 5:
If we divide 1621 by 180, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we take 1620 away from 1621, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 180

Going ahead to step 6:
180 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 790.0
Subtract 0 from 15 to get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 180

Moving on to step 7:
When dividing 152 by 180, we get 0 with a remainder of 152.
The next digit of our result is 0. 
Result so far: 7900.0
If we subtract 0 from 152, we get 152.
Bring next digit (2) of the dividend behind the 152 and repeat the process: 1522 / 180

Going ahead to step 8:
If we divide 1522 by 180, we get 8 and a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 79008.0
Deduct 1440 from 1522 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
If we divide 820 by 180, we get 4 and a remainder of 100.
The next digit of our result is 4. 
Result so far: 79008.4
If we take 720 away from 820, we end up 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.

Going ahead to step 10:
180 goes into 1000 5 times with a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 79008.45
If we take 900 away from 1000, we end up 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.

Going ahead to step 11:
1000 divided by 180 is 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 79008.455
If we subtract 900 from 1000, we 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.

After the division, we end up with 79008.455 and a remainder of 0.01.
