We're dividing 203524 by 900 
The aim is to understand the frequency of 900 in 203524.

Advancing to step 1:
2 divided by 900 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 900

Step 2:
The number 900 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 900

Going ahead to step 3:
203 divided by 900 is 0 with a remainder of 203.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 203 to get 203.
Append the next digit (5) from the dividend to 203 and continue with: 2035 / 900

Moving on to step 4:
900 can be fit into 2035 2 times, resulting in a remainder of 235.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1800 from 2035 to get 235.
Fetch the next digit (2) from the dividend, attach it to 235 and continue: 2352 / 900

Moving on to step 5:
When dividing 2352 by 900, we get 2 with a remainder of 552.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 1800 from 2352 to get 552.
Grab the next digit (4) from the dividend, add it to 552, then carry on: 5524 / 900

Advancing to step 6:
If we divide 5524 by 900, we get 6 and a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 226.0
The remainder is 124 after subtracting 5400 from 5524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 7:
When dividing 1240 by 900, we get 1 with a remainder of 340.
Use 1 as the next digit of our solution. 
Result so far: 226.1
If we take 900 away from 1240, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 8:
If we divide 3400 by 900, we get 3 and a remainder of 700.
The number 3 becomes the next digit in our result. 
Result so far: 226.13
The remainder is 700 after subtracting 2700 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 9:
900 goes into 7000 7 times with a remainder of 700.
Write down 7 as next digit of the result. 
Result so far: 226.137
The remainder is 700 after subtracting 6300 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 10:
If we divide 7000 by 900, we get 7 and a remainder of 700.
Use 7 as the next digit of our solution. 
Result so far: 226.1377
Subtracting 6300 from 7000 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

After the division, we end up with 226.1377 and a remainder of 0.007.
