20008779 divided by 900 
The aim is to understand the frequency of 900 in 20008779.

On to step 1:
The number 900 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 900

Going ahead to step 2:
900 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 900

On to step 3:
When dividing 200 by 900, we get 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 200 leaves us with 200.
Take the next digit (0) from the dividend and append it to 200, then repeat: 2000 / 900

Advancing to step 4:
When dividing 2000 by 900, we get 2 with a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 1800 from 2000 leaves us with 200.
Append the next digit (8) from the dividend to 200 and continue with: 2008 / 900

Let's proceed to step 5:
900 goes into 2008 2 times with a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 1800 from 2008 to get 208.
Grab the next digit (7) from the dividend, add it to 208, then carry on: 2087 / 900

On to step 6:
When dividing 2087 by 900, we get 2 with a remainder of 287.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
The remainder is 287 after subtracting 1800 from 2087.
Take the next digit (7) from the dividend and append it to 287, then repeat: 2877 / 900

Going ahead to step 7:
900 can be fit into 2877 3 times, resulting in a remainder of 177.
Write down 3 as next digit of the result. 
Result so far: 2223.0
Subtracting 2700 from 2877 leaves us with 177.
Grab the next digit (9) from the dividend, add it to 177, then carry on: 1779 / 900

Going ahead to step 8:
900 can be fit into 1779 1 times, resulting in a remainder of 879.
The number 1 becomes the next digit in our result. 
Result so far: 22231.0
If we take 900 away from 1779, we end up with 879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8790, and continue the process.

Step 9:
900 goes into 8790 9 times with a remainder of 690.
Record the quotient 9 as the next digit in the result. 
Result so far: 22231.9
Deduct 8100 from 8790 and we're left with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Advancing to step 10:
900 can be fit into 6900 7 times, resulting in a remainder of 600.
Put 7 as the next digit of the answer. 
Result so far: 22231.97
If we take 6300 away from 6900, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 11:
6000 divided by 900 is 6 with a remainder of 600.
Write down 6 as next digit of the result. 
Result so far: 22231.976
Subtract 5400 from 6000 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 12:
6000 divided by 900 is 6 with a remainder of 600.
The next digit of our result is 6. 
Result so far: 22231.9766
If we subtract 5400 from 6000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 22231.9766 with a balance of 0.006.
