We divide 65472590 by 900
The aim is to understand the frequency of 900 in 65472590.

Step 1:
900 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 900

Step 2:
900 goes into 65 0 times with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 900

Moving on to step 3:
The number 900 fits into 654 0 times, leaving a remainder of 654.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 654 to get 654.
Take the next digit (7) from the dividend and append it to 654, then repeat: 6547 / 900

Going ahead to step 4:
If we divide 6547 by 900, we get 7 and a remainder of 247.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 247 after subtracting 6300 from 6547.
Bring next digit (2) of the dividend behind the 247 and repeat the process: 2472 / 900

Step 5:
When dividing 2472 by 900, we get 2 with a remainder of 672.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 1800 from 2472 and we're left with 672.
Append the next digit (5) from the dividend to 672 and continue with: 6725 / 900

Let's proceed to step 6:
900 goes into 6725 7 times with a remainder of 425.
Write down 7 as next digit of the result. 
Result so far: 727.0
The remainder is 425 after subtracting 6300 from 6725.
Fetch the next digit (9) from the dividend, attach it to 425 and continue: 4259 / 900

Let's proceed to step 7:
900 can be fit into 4259 4 times, resulting in a remainder of 659.
Record the quotient 4 as the next digit in the result. 
Result so far: 7274.0
Deduct 3600 from 4259 and we're left with 659.
Take the next digit (0) from the dividend and append it to 659, then repeat: 6590 / 900

Advancing to step 8:
If we divide 6590 by 900, we get 7 and a remainder of 290.
The number 7 becomes the next digit in our result. 
Result so far: 72747.0
Deduct 6300 from 6590 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 9:
2900 divided by 900 is 3 with a remainder of 200.
Record the quotient 3 as the next digit in the result. 
Result so far: 72747.3
Subtracting 2700 from 2900 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
900 can be fit into 2000 2 times, resulting in a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 72747.32
The remainder is 200 after subtracting 1800 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
900 goes into 2000 2 times with a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 72747.322
Deduct 1800 from 2000 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 72747.322, with a leftover of 0.02.
