Let's divide 71913753 by 180
The aim is to understand the frequency of 180 in 71913753.

Moving on to step 1:
180 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 180

Advancing to step 2:
71 divided by 180 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Take the next digit (9) from the dividend and append it to 71, then repeat: 719 / 180

Step 3:
180 goes into 719 3 times with a remainder of 179.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 179 after subtracting 540 from 719.
Take the next digit (1) from the dividend and append it to 179, then repeat: 1791 / 180

Going ahead to step 4:
If we divide 1791 by 180, we get 9 and a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 1620 from 1791, we get 171.
Bring next digit (3) of the dividend behind the 171 and repeat the process: 1713 / 180

Advancing to step 5:
If we divide 1713 by 180, we get 9 and a remainder of 93.
Record the quotient 9 as the next digit in the result. 
Result so far: 399.0
Subtracting 1620 from 1713 leaves us with 93.
Append the next digit (7) from the dividend to 93 and continue with: 937 / 180

Moving on to step 6:
The number 180 fits into 937 5 times, leaving a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 3995.0
The remainder is 37 after subtracting 900 from 937.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 180

Moving on to step 7:
If we divide 375 by 180, we get 2 and a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 39952.0
Subtracting 360 from 375 leaves us with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 180

Going ahead to step 8:
180 goes into 153 0 times with a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 399520.0
Subtracting 0 from 153 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Let's proceed to step 9:
180 can be fit into 1530 8 times, resulting in a remainder of 90.
Use 8 as the next digit of our solution. 
Result so far: 399520.8
Subtracting 1440 from 1530 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
900 divided by 180 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 399520.85
If we take 900 away from 900, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 180, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 399520.85
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
180 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 399520.85
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 399520.85 with a remainder of 0.0.
