We look at the division of 45140133 by 900 
The aim is to understand the frequency of 900 in 45140133.

Going ahead to step 1:
900 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 900

On to step 2:
45 divided by 900 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 900

Moving on to step 3:
900 can be fit into 451 0 times, resulting in a remainder of 451.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 451, we end up with 451.
Take the next digit (4) from the dividend and append it to 451, then repeat: 4514 / 900

On to step 4:
The number 900 fits into 4514 5 times, leaving a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 14 after subtracting 4500 from 4514.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 900

Going ahead to step 5:
900 goes into 140 0 times with a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtracting 0 from 140 leaves us with 140.
Grab the next digit (1) from the dividend, add it to 140, then carry on: 1401 / 900

Step 6:
When dividing 1401 by 900, we get 1 with a remainder of 501.
Write down 1 as next digit of the result. 
Result so far: 501.0
If we subtract 900 from 1401, we get 501.
Append the next digit (3) from the dividend to 501 and continue with: 5013 / 900

On to step 7:
900 goes into 5013 5 times with a remainder of 513.
The number 5 becomes the next digit in our result. 
Result so far: 5015.0
Deduct 4500 from 5013 and we're left with 513.
Grab the next digit (3) from the dividend, add it to 513, then carry on: 5133 / 900

On to step 8:
900 can be fit into 5133 5 times, resulting in a remainder of 633.
Put 5 as the next digit of the answer. 
Result so far: 50155.0
If we subtract 4500 from 5133, we get 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Advancing to step 9:
900 can be fit into 6330 7 times, resulting in a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 50155.7
Deduct 6300 from 6330 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
900 goes into 300 0 times with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 50155.7
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 11:
900 can be fit into 3000 3 times, resulting in a remainder of 300.
The number 3 becomes the next digit in our result. 
Result so far: 50155.703
The remainder is 300 after subtracting 2700 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 12:
900 can be fit into 3000 3 times, resulting in a remainder of 300.
Put 3 as the next digit of the answer. 
Result so far: 50155.7033
Subtract 2700 from 3000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 50155.7033, with a leftover of 0.003.
