We're dividing 10389455 by 180 
The aim is to understand the frequency of 180 in 10389455.

Going ahead to step 1:
180 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 180

Advancing to step 2:
When dividing 10 by 180, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 180

Advancing to step 3:
If we divide 103 by 180, we get 0 and a remainder of 103.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 103 leaves us with 103.
Fetch the next digit (8) from the dividend, attach it to 103 and continue: 1038 / 180

On to step 4:
The number 180 fits into 1038 5 times, leaving a remainder of 138.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 138 after subtracting 900 from 1038.
Grab the next digit (9) from the dividend, add it to 138, then carry on: 1389 / 180

Let's proceed to step 5:
The number 180 fits into 1389 7 times, leaving a remainder of 129.
Use 7 as the next digit of our solution. 
Result so far: 57.0
The remainder is 129 after subtracting 1260 from 1389.
Bring next digit (4) of the dividend behind the 129 and repeat the process: 1294 / 180

Let's proceed to step 6:
If we divide 1294 by 180, we get 7 and a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 577.0
Subtracting 1260 from 1294 leaves us with 34.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 180

Let's proceed to step 7:
180 can be fit into 345 1 times, resulting in a remainder of 165.
The next digit of our result is 1. 
Result so far: 5771.0
If we subtract 180 from 345, we get 165.
Append the next digit (5) from the dividend to 165 and continue with: 1655 / 180

Advancing to step 8:
180 goes into 1655 9 times with a remainder of 35.
Record the quotient 9 as the next digit in the result. 
Result so far: 57719.0
Subtract 1620 from 1655 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
350 divided by 180 is 1 with a remainder of 170.
The number 1 becomes the next digit in our result. 
Result so far: 57719.1
The remainder is 170 after subtracting 180 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 10:
180 goes into 1700 9 times with a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 57719.19
Subtracting 1620 from 1700 leaves us 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.

Moving on to step 11:
If we divide 800 by 180, we get 4 and a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 57719.194
If we subtract 720 from 800, 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 12:
800 divided by 180 is 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 57719.1944
Deduct 720 from 800 and we're left 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.

After the division, we end up with 57719.1944 and a remainder of 0.0008.
