We look at the division of 54835501 by 900 
The aim is to understand the frequency of 900 in 54835501.

Going ahead to step 1:
5 divided by 900 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 900

Let's proceed to step 2:
900 goes into 54 0 times with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Grab the next digit (8) from the dividend, add it to 54, then carry on: 548 / 900

Advancing to step 3:
900 goes into 548 0 times with a remainder of 548.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 548, we end up with 548.
Append the next digit (3) from the dividend to 548 and continue with: 5483 / 900

Moving on to step 4:
900 can be fit into 5483 6 times, resulting in a remainder of 83.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 5400 from 5483 and we're left with 83.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 900

Step 5:
If we divide 835 by 900, we get 0 and a remainder of 835.
The next digit of our result is 0. 
Result so far: 60.0
Deduct 0 from 835 and we're left with 835.
Grab the next digit (5) from the dividend, add it to 835, then carry on: 8355 / 900

Let's proceed to step 6:
900 can be fit into 8355 9 times, resulting in a remainder of 255.
The next digit of our result is 9. 
Result so far: 609.0
Subtract 8100 from 8355 to get 255.
Bring next digit (0) of the dividend behind the 255 and repeat the process: 2550 / 900

Going ahead to step 7:
If we divide 2550 by 900, we get 2 and a remainder of 750.
The next digit of our result is 2. 
Result so far: 6092.0
If we take 1800 away from 2550, we end up with 750.
Bring next digit (1) of the dividend behind the 750 and repeat the process: 7501 / 900

Advancing to step 8:
When dividing 7501 by 900, we get 8 with a remainder of 301.
Use 8 as the next digit of our solution. 
Result so far: 60928.0
The remainder is 301 after subtracting 7200 from 7501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 9:
900 goes into 3010 3 times with a remainder of 310.
Write down 3 as next digit of the result. 
Result so far: 60928.3
If we subtract 2700 from 3010, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 10:
The number 900 fits into 3100 3 times, leaving a remainder of 400.
Write down 3 as next digit of the result. 
Result so far: 60928.33
Subtract 2700 from 3100 to 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.

After the division, we end up with 60928.33 and a remainder of 0.4.
