We divide 77319505 by 900
We want to figure out the number of times 77319505 can be divided by 900.

Let's proceed to step 1:
900 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 900

Let's proceed to step 2:
77 divided by 900 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (3) from the dividend and append it to 77, then repeat: 773 / 900

Advancing to step 3:
773 divided by 900 is 0 with a remainder of 773.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 773, we get 773.
Bring next digit (1) of the dividend behind the 773 and repeat the process: 7731 / 900

Moving on to step 4:
If we divide 7731 by 900, we get 8 and a remainder of 531.
The next digit of our result is 8. 
Result so far: 8.0
If we take 7200 away from 7731, we end up with 531.
Append the next digit (9) from the dividend to 531 and continue with: 5319 / 900

Going ahead to step 5:
If we divide 5319 by 900, we get 5 and a remainder of 819.
The next digit of our result is 5. 
Result so far: 85.0
Deduct 4500 from 5319 and we're left with 819.
Append the next digit (5) from the dividend to 819 and continue with: 8195 / 900

Let's proceed to step 6:
900 goes into 8195 9 times with a remainder of 95.
The number 9 becomes the next digit in our result. 
Result so far: 859.0
Subtracting 8100 from 8195 leaves us with 95.
Bring next digit (0) of the dividend behind the 95 and repeat the process: 950 / 900

Advancing to step 7:
900 can be fit into 950 1 times, resulting in a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 8591.0
The remainder is 50 after subtracting 900 from 950.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 900

On to step 8:
When dividing 505 by 900, we get 0 with a remainder of 505.
Write down 0 as next digit of the result. 
Result so far: 85910.0
The remainder is 505 after subtracting 0 from 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 9:
If we divide 5050 by 900, we get 5 and a remainder of 550.
The number 5 becomes the next digit in our result. 
Result so far: 85910.5
Subtract 4500 from 5050 to get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Going ahead to step 10:
900 can be fit into 5500 6 times, resulting in a remainder of 100.
Write down 6 as next digit of the result. 
Result so far: 85910.56
The remainder is 100 after subtracting 5400 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
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: 85910.561
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.

On to step 12:
The number 900 fits into 1000 1 times, leaving a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 85910.5611
Subtracting 900 from 1000 leaves us 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.

In conclusion, the division gives 85910.5611 with a balance of 0.001.
