We divide 25608158 by 900
The aim is to understand the frequency of 900 in 25608158.

On to step 1:
When dividing 2 by 900, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 900

Step 2:
When dividing 25 by 900, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 900

Advancing to step 3:
When dividing 256 by 900, we get 0 with a remainder of 256.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 256 after subtracting 0 from 256.
Append the next digit (0) from the dividend to 256 and continue with: 2560 / 900

Let's proceed to step 4:
The number 900 fits into 2560 2 times, leaving a remainder of 760.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1800 away from 2560, we end up with 760.
Include the next digit (8) from the dividend after 760, then repeat: 7608 / 900

Advancing to step 5:
If we divide 7608 by 900, we get 8 and a remainder of 408.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 7200 from 7608, we get 408.
Bring next digit (1) of the dividend behind the 408 and repeat the process: 4081 / 900

Advancing to step 6:
When dividing 4081 by 900, we get 4 with a remainder of 481.
Use 4 as the next digit of our solution. 
Result so far: 284.0
If we take 3600 away from 4081, we end up with 481.
Take the next digit (5) from the dividend and append it to 481, then repeat: 4815 / 900

Going ahead to step 7:
When dividing 4815 by 900, we get 5 with a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 2845.0
Deduct 4500 from 4815 and we're left with 315.
Take the next digit (8) from the dividend and append it to 315, then repeat: 3158 / 900

Going ahead to step 8:
If we divide 3158 by 900, we get 3 and a remainder of 458.
Record the quotient 3 as the next digit in the result. 
Result so far: 28453.0
If we subtract 2700 from 3158, we get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Step 9:
900 goes into 4580 5 times with a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 28453.5
The remainder is 80 after subtracting 4500 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
900 can be fit into 800 0 times, resulting in a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 28453.5
The remainder is 800 after subtracting 0 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

On to step 11:
The number 900 fits into 8000 8 times, leaving a remainder of 800.
The number 8 becomes the next digit in our result. 
Result so far: 28453.508
The remainder is 800 after subtracting 7200 from 8000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Advancing to step 12:
900 can be fit into 8000 8 times, resulting in a remainder of 800.
Write down 8 as next digit of the result. 
Result so far: 28453.5088
Deduct 7200 from 8000 and we're left with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

The final outcome is 28453.5088, with a leftover of 0.008.
