Let's divide 10259025 by 900
The aim is to understand the frequency of 900 in 10259025.

Advancing to step 1:
When dividing 1 by 900, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 900

Advancing to step 2:
When dividing 10 by 900, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 900

Advancing to step 3:
900 goes into 102 0 times with a remainder of 102.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 102 and we're left with 102.
Fetch the next digit (5) from the dividend, attach it to 102 and continue: 1025 / 900

Moving on to step 4:
1025 divided by 900 is 1 with a remainder of 125.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 900 from 1025, we get 125.
Append the next digit (9) from the dividend to 125 and continue with: 1259 / 900

Step 5:
If we divide 1259 by 900, we get 1 and a remainder of 359.
The next digit of our result is 1. 
Result so far: 11.0
If we take 900 away from 1259, we end up with 359.
Append the next digit (0) from the dividend to 359 and continue with: 3590 / 900

Advancing to step 6:
When dividing 3590 by 900, we get 3 with a remainder of 890.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Subtracting 2700 from 3590 leaves us with 890.
Bring next digit (2) of the dividend behind the 890 and repeat the process: 8902 / 900

Going ahead to step 7:
The number 900 fits into 8902 9 times, leaving a remainder of 802.
The next digit of our result is 9. 
Result so far: 1139.0
Deduct 8100 from 8902 and we're left with 802.
Append the next digit (5) from the dividend to 802 and continue with: 8025 / 900

Advancing to step 8:
If we divide 8025 by 900, we get 8 and a remainder of 825.
The number 8 becomes the next digit in our result. 
Result so far: 11398.0
If we take 7200 away from 8025, we end up with 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Going ahead to step 9:
8250 divided by 900 is 9 with a remainder of 150.
Put 9 as the next digit of the answer. 
Result so far: 11398.9
If we subtract 8100 from 8250, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
1500 divided by 900 is 1 with a remainder of 600.
The next digit of our result is 1. 
Result so far: 11398.91
If we subtract 900 from 1500, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 11:
When dividing 6000 by 900, we get 6 with a remainder of 600.
The number 6 becomes the next digit in our result. 
Result so far: 11398.916
If we take 5400 away from 6000, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 12:
The number 900 fits into 6000 6 times, leaving a remainder of 600.
Write down 6 as next digit of the result. 
Result so far: 11398.9166
If we take 5400 away from 6000, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 11398.9166 with a balance of 0.006.
