We divide 3130396 by 180
The aim is to understand the frequency of 180 in 3130396.

Going ahead to step 1:
180 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 180

Going ahead to step 2:
180 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 180

Let's proceed to step 3:
If we divide 313 by 180, we get 1 and a remainder of 133.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 180 away from 313, we end up with 133.
Bring next digit (0) of the dividend behind the 133 and repeat the process: 1330 / 180

Advancing to step 4:
The number 180 fits into 1330 7 times, leaving a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 1260 from 1330 to get 70.
Bring next digit (3) of the dividend behind the 70 and repeat the process: 703 / 180

Advancing to step 5:
180 can be fit into 703 3 times, resulting in a remainder of 163.
The next digit of our result is 3. 
Result so far: 173.0
The remainder is 163 after subtracting 540 from 703.
Grab the next digit (9) from the dividend, add it to 163, then carry on: 1639 / 180

Going ahead to step 6:
1639 divided by 180 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 1739.0
If we take 1620 away from 1639, we end up with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 180

Advancing to step 7:
When dividing 196 by 180, we get 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 17391.0
If we subtract 180 from 196, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
180 goes into 160 0 times with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 17391.0
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 9:
1600 divided by 180 is 8 with a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 17391.08
If we subtract 1440 from 1600, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
When dividing 1600 by 180, we get 8 with a remainder of 160.
Use 8 as the next digit of our solution. 
Result so far: 17391.088
Subtract 1440 from 1600 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 17391.088 with a remainder of 0.016.
