86879480 divided by 900 
We want to figure out the number of times 86879480 can be divided by 900.

Advancing to step 1:
When dividing 8 by 900, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 900

Moving on to step 2:
900 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 900

Let's proceed to step 3:
900 can be fit into 868 0 times, resulting in a remainder of 868.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 868 leaves us with 868.
Include the next digit (7) from the dividend after 868, then repeat: 8687 / 900

On to step 4:
900 goes into 8687 9 times with a remainder of 587.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 8100 from 8687 and we're left with 587.
Include the next digit (9) from the dividend after 587, then repeat: 5879 / 900

Step 5:
900 can be fit into 5879 6 times, resulting in a remainder of 479.
The next digit of our result is 6. 
Result so far: 96.0
Deduct 5400 from 5879 and we're left with 479.
Bring next digit (4) of the dividend behind the 479 and repeat the process: 4794 / 900

Going ahead to step 6:
The number 900 fits into 4794 5 times, leaving a remainder of 294.
Put 5 as the next digit of the answer. 
Result so far: 965.0
Deduct 4500 from 4794 and we're left with 294.
Take the next digit (8) from the dividend and append it to 294, then repeat: 2948 / 900

On to step 7:
If we divide 2948 by 900, we get 3 and a remainder of 248.
The number 3 becomes the next digit in our result. 
Result so far: 9653.0
The remainder is 248 after subtracting 2700 from 2948.
Take the next digit (0) from the dividend and append it to 248, then repeat: 2480 / 900

Step 8:
When dividing 2480 by 900, we get 2 with a remainder of 680.
The next digit of our result is 2. 
Result so far: 96532.0
The remainder is 680 after subtracting 1800 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 9:
900 goes into 6800 7 times with a remainder of 500.
The next digit of our result is 7. 
Result so far: 96532.7
If we take 6300 away from 6800, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 10:
When dividing 5000 by 900, we get 5 with a remainder of 500.
Record the quotient 5 as the next digit in the result. 
Result so far: 96532.75
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.

Step 11:
If we divide 5000 by 900, we get 5 and a remainder of 500.
Write down 5 as next digit of the result. 
Result so far: 96532.755
The remainder is 500 after subtracting 4500 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 96532.755 with a remaining 0.05.
