53101888 divided by 900 
The aim is to understand the frequency of 900 in 53101888.

Moving on to step 1:
When dividing 5 by 900, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 900

Step 2:
900 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 900

Moving on to step 3:
When dividing 531 by 900, we get 0 with a remainder of 531.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 531 leaves us with 531.
Bring next digit (0) of the dividend behind the 531 and repeat the process: 5310 / 900

Advancing to step 4:
5310 divided by 900 is 5 with a remainder of 810.
The next digit of our result is 5. 
Result so far: 5.0
If we take 4500 away from 5310, we end up with 810.
Fetch the next digit (1) from the dividend, attach it to 810 and continue: 8101 / 900

On to step 5:
If we divide 8101 by 900, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Deduct 8100 from 8101 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 900

Going ahead to step 6:
900 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 590.0
If we take 0 away from 18, we end up with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 900

Moving on to step 7:
188 divided by 900 is 0 with a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 5900.0
The remainder is 188 after subtracting 0 from 188.
Include the next digit (8) from the dividend after 188, then repeat: 1888 / 900

Going ahead to step 8:
The number 900 fits into 1888 2 times, leaving a remainder of 88.
Put 2 as the next digit of the answer. 
Result so far: 59002.0
Subtract 1800 from 1888 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 9:
The number 900 fits into 880 0 times, leaving a remainder of 880.
Write down 0 as next digit of the result. 
Result so far: 59002.0
Subtracting 0 from 880 leaves us with 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8800, and continue the process.

Let's proceed to step 10:
900 can be fit into 8800 9 times, resulting in a remainder of 700.
Write down 9 as next digit of the result. 
Result so far: 59002.09
The remainder is 700 after subtracting 8100 from 8800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 11:
900 goes into 7000 7 times with a remainder of 700.
The next digit of our result is 7. 
Result so far: 59002.097
Subtracting 6300 from 7000 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 12:
If we divide 7000 by 900, we get 7 and a remainder of 700.
Record the quotient 7 as the next digit in the result. 
Result so far: 59002.0977
Subtract 6300 from 7000 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The quotient of the division is 59002.0977, and the remainder is 0.007.
