We look at the division of 22231075 by 900 
The aim is to understand the frequency of 900 in 22231075.

On to step 1:
900 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 900

Let's proceed to step 2:
When dividing 22 by 900, we get 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Append the next digit (2) from the dividend to 22 and continue with: 222 / 900

Going ahead to step 3:
900 goes into 222 0 times with a remainder of 222.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 222, we get 222.
Include the next digit (3) from the dividend after 222, then repeat: 2223 / 900

Going ahead to step 4:
900 goes into 2223 2 times with a remainder of 423.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1800 from 2223 and we're left with 423.
Bring next digit (1) of the dividend behind the 423 and repeat the process: 4231 / 900

Going ahead to step 5:
4231 divided by 900 is 4 with a remainder of 631.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 3600 from 4231, we get 631.
Grab the next digit (0) from the dividend, add it to 631, then carry on: 6310 / 900

Advancing to step 6:
The number 900 fits into 6310 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 247.0
If we take 6300 away from 6310, we end up with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 900

Advancing to step 7:
900 goes into 107 0 times with a remainder of 107.
Use 0 as the next digit of our solution. 
Result so far: 2470.0
The remainder is 107 after subtracting 0 from 107.
Append the next digit (5) from the dividend to 107 and continue with: 1075 / 900

Moving on to step 8:
900 can be fit into 1075 1 times, resulting in a remainder of 175.
Use 1 as the next digit of our solution. 
Result so far: 24701.0
Subtracting 900 from 1075 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 9:
When dividing 1750 by 900, we get 1 with a remainder of 850.
Record the quotient 1 as the next digit in the result. 
Result so far: 24701.1
Subtracting 900 from 1750 leaves us with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Advancing to step 10:
The number 900 fits into 8500 9 times, leaving a remainder of 400.
Put 9 as the next digit of the answer. 
Result so far: 24701.19
If we subtract 8100 from 8500, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 11:
When dividing 4000 by 900, we get 4 with a remainder of 400.
Put 4 as the next digit of the answer. 
Result so far: 24701.194
Subtracting 3600 from 4000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 12:
The number 900 fits into 4000 4 times, leaving a remainder of 400.
The number 4 becomes the next digit in our result. 
Result so far: 24701.1944
The remainder is 400 after subtracting 3600 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 24701.1944, with a leftover of 0.004.
