Let's divide 74919509 by 180
The aim is to understand the frequency of 180 in 74919509.

On to step 1:
180 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 180

On to step 2:
The number 180 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Append the next digit (9) from the dividend to 74 and continue with: 749 / 180

Step 3:
If we divide 749 by 180, we get 4 and a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 720 from 749 to get 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 180

Advancing to step 4:
When dividing 291 by 180, we get 1 with a remainder of 111.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
The remainder is 111 after subtracting 180 from 291.
Fetch the next digit (9) from the dividend, attach it to 111 and continue: 1119 / 180

On to step 5:
180 goes into 1119 6 times with a remainder of 39.
Put 6 as the next digit of the answer. 
Result so far: 416.0
Deduct 1080 from 1119 and we're left with 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 180

Going ahead to step 6:
395 divided by 180 is 2 with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 4162.0
The remainder is 35 after subtracting 360 from 395.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 180

Step 7:
When dividing 350 by 180, we get 1 with a remainder of 170.
Use 1 as the next digit of our solution. 
Result so far: 41621.0
The remainder is 170 after subtracting 180 from 350.
Bring next digit (9) of the dividend behind the 170 and repeat the process: 1709 / 180

Going ahead to step 8:
The number 180 fits into 1709 9 times, leaving a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 416219.0
If we take 1620 away from 1709, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 9:
If we divide 890 by 180, we get 4 and a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 416219.4
If we subtract 720 from 890, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
The number 180 fits into 1700 9 times, leaving a remainder of 80.
Put 9 as the next digit of the answer. 
Result so far: 416219.49
If we subtract 1620 from 1700, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
180 can be fit into 800 4 times, resulting in a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 416219.494
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
180 goes into 800 4 times with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 416219.4944
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 416219.4944 with a remainder of 0.0008.
