66192913 divided by 900 
The aim is to understand the frequency of 900 in 66192913.

Moving on to step 1:
900 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 900

Going ahead to step 2:
900 goes into 66 0 times with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (1) from the dividend, add it to 66, then carry on: 661 / 900

Let's proceed to step 3:
661 divided by 900 is 0 with a remainder of 661.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 661, we end up with 661.
Take the next digit (9) from the dividend and append it to 661, then repeat: 6619 / 900

Step 4:
900 can be fit into 6619 7 times, resulting in a remainder of 319.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 6300 from 6619 and we're left with 319.
Take the next digit (2) from the dividend and append it to 319, then repeat: 3192 / 900

Let's proceed to step 5:
900 goes into 3192 3 times with a remainder of 492.
The next digit of our result is 3. 
Result so far: 73.0
Subtract 2700 from 3192 to get 492.
Bring next digit (9) of the dividend behind the 492 and repeat the process: 4929 / 900

Advancing to step 6:
4929 divided by 900 is 5 with a remainder of 429.
Record the quotient 5 as the next digit in the result. 
Result so far: 735.0
If we subtract 4500 from 4929, we get 429.
Bring next digit (1) of the dividend behind the 429 and repeat the process: 4291 / 900

Let's proceed to step 7:
900 goes into 4291 4 times with a remainder of 691.
The number 4 becomes the next digit in our result. 
Result so far: 7354.0
If we take 3600 away from 4291, we end up with 691.
Take the next digit (3) from the dividend and append it to 691, then repeat: 6913 / 900

Let's proceed to step 8:
The number 900 fits into 6913 7 times, leaving a remainder of 613.
Write down 7 as next digit of the result. 
Result so far: 73547.0
Deduct 6300 from 6913 and we're left with 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

On to step 9:
6130 divided by 900 is 6 with a remainder of 730.
The next digit of our result is 6. 
Result so far: 73547.6
Subtract 5400 from 6130 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 10:
7300 divided by 900 is 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 73547.68
The remainder is 100 after subtracting 7200 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
900 can be fit into 1000 1 times, resulting in a remainder of 100.
Use 1 as the next digit of our solution. 
Result so far: 73547.681
If we take 900 away from 1000, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 12:
If we divide 1000 by 900, we get 1 and a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 73547.6811
Subtract 900 from 1000 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 73547.6811 and a remainder of 0.001.
