We're dividing 79017449 by 900 
The aim is to understand the frequency of 900 in 79017449.

Going ahead to step 1:
7 divided by 900 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 900

Going ahead to step 2:
900 goes into 79 0 times with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 900

On to step 3:
900 can be fit into 790 0 times, resulting in a remainder of 790.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 790, we end up with 790.
Include the next digit (1) from the dividend after 790, then repeat: 7901 / 900

Moving on to step 4:
If we divide 7901 by 900, we get 8 and a remainder of 701.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 7200 from 7901 to get 701.
Bring next digit (7) of the dividend behind the 701 and repeat the process: 7017 / 900

On to step 5:
900 goes into 7017 7 times with a remainder of 717.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 6300 from 7017 to get 717.
Bring next digit (4) of the dividend behind the 717 and repeat the process: 7174 / 900

Step 6:
The number 900 fits into 7174 7 times, leaving a remainder of 874.
The next digit of our result is 7. 
Result so far: 877.0
Deduct 6300 from 7174 and we're left with 874.
Append the next digit (4) from the dividend to 874 and continue with: 8744 / 900

Moving on to step 7:
900 goes into 8744 9 times with a remainder of 644.
Use 9 as the next digit of our solution. 
Result so far: 8779.0
Subtracting 8100 from 8744 leaves us with 644.
Include the next digit (9) from the dividend after 644, then repeat: 6449 / 900

Advancing to step 8:
The number 900 fits into 6449 7 times, leaving a remainder of 149.
Write down 7 as next digit of the result. 
Result so far: 87797.0
If we take 6300 away from 6449, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Step 9:
When dividing 1490 by 900, we get 1 with a remainder of 590.
The number 1 becomes the next digit in our result. 
Result so far: 87797.1
If we subtract 900 from 1490, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 10:
900 can be fit into 5900 6 times, resulting in a remainder of 500.
Record the quotient 6 as the next digit in the result. 
Result so far: 87797.16
The remainder is 500 after subtracting 5400 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 11:
The number 900 fits into 5000 5 times, leaving a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 87797.165
If we subtract 4500 from 5000, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 12:
When dividing 5000 by 900, we get 5 with a remainder of 500.
The next digit of our result is 5. 
Result so far: 87797.1655
Subtract 4500 from 5000 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 87797.1655, and the remainder is 0.005.
