We look at the division of 87475089 by 900 
We want to figure out the number of times 87475089 can be divided by 900.

Going ahead to step 1:
When dividing 8 by 900, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 900

Let's proceed to step 2:
87 divided by 900 is 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 900

Step 3:
900 can be fit into 874 0 times, resulting in a remainder of 874.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 874 and we're left with 874.
Fetch the next digit (7) from the dividend, attach it to 874 and continue: 8747 / 900

Step 4:
When dividing 8747 by 900, we get 9 with a remainder of 647.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 8100 away from 8747, we end up with 647.
Append the next digit (5) from the dividend to 647 and continue with: 6475 / 900

On to step 5:
When dividing 6475 by 900, we get 7 with a remainder of 175.
The next digit of our result is 7. 
Result so far: 97.0
The remainder is 175 after subtracting 6300 from 6475.
Take the next digit (0) from the dividend and append it to 175, then repeat: 1750 / 900

On to step 6:
When dividing 1750 by 900, we get 1 with a remainder of 850.
The next digit of our result is 1. 
Result so far: 971.0
Subtracting 900 from 1750 leaves us with 850.
Bring next digit (8) of the dividend behind the 850 and repeat the process: 8508 / 900

Let's proceed to step 7:
The number 900 fits into 8508 9 times, leaving a remainder of 408.
The next digit of our result is 9. 
Result so far: 9719.0
Subtracting 8100 from 8508 leaves us with 408.
Grab the next digit (9) from the dividend, add it to 408, then carry on: 4089 / 900

Step 8:
4089 divided by 900 is 4 with a remainder of 489.
Record the quotient 4 as the next digit in the result. 
Result so far: 97194.0
Subtract 3600 from 4089 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

On to step 9:
900 can be fit into 4890 5 times, resulting in a remainder of 390.
The number 5 becomes the next digit in our result. 
Result so far: 97194.5
Subtract 4500 from 4890 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 10:
If we divide 3900 by 900, we get 4 and a remainder of 300.
The number 4 becomes the next digit in our result. 
Result so far: 97194.54
Deduct 3600 from 3900 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
If we divide 3000 by 900, we get 3 and a remainder of 300.
Write down 3 as next digit of the result. 
Result so far: 97194.543
If we take 2700 away from 3000, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 12:
The number 900 fits into 3000 3 times, leaving a remainder of 300.
Use 3 as the next digit of our solution. 
Result so far: 97194.5433
The remainder is 300 after subtracting 2700 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final outcome is 97194.5433, with a leftover of 0.003.
