We're dividing 86400516 by 900 
We want to divide 86400516 by 900.

Advancing to step 1:
When dividing 8 by 900, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 900

Let's proceed to step 2:
900 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 900

Moving on to step 3:
If we divide 864 by 900, we get 0 and a remainder of 864.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 864 to get 864.
Take the next digit (0) from the dividend and append it to 864, then repeat: 8640 / 900

Moving on to step 4:
900 goes into 8640 9 times with a remainder of 540.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 8100 from 8640, we get 540.
Grab the next digit (0) from the dividend, add it to 540, then carry on: 5400 / 900

Going ahead to step 5:
900 goes into 5400 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 96.0
The remainder is 0 after subtracting 5400 from 5400.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 900

Step 6:
The number 900 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 960.0
Subtract 0 from 5 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 900

Let's proceed to step 7:
900 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 9600.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (6) of the dividend behind the 51 and repeat the process: 516 / 900

Step 8:
The number 900 fits into 516 0 times, leaving a remainder of 516.
Put 0 as the next digit of the answer. 
Result so far: 96000.0
Subtracting 0 from 516 leaves us with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

On to step 9:
When dividing 5160 by 900, we get 5 with a remainder of 660.
Use 5 as the next digit of our solution. 
Result so far: 96000.5
The remainder is 660 after subtracting 4500 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 10:
The number 900 fits into 6600 7 times, leaving a remainder of 300.
The next digit of our result is 7. 
Result so far: 96000.57
The remainder is 300 after subtracting 6300 from 6600.
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 11:
900 goes into 3000 3 times with a remainder of 300.
The number 3 becomes the next digit in our result. 
Result so far: 96000.573
Subtracting 2700 from 3000 leaves us 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.

Step 12:
The number 900 fits into 3000 3 times, leaving a remainder of 300.
Put 3 as the next digit of the answer. 
Result so far: 96000.5733
Subtract 2700 from 3000 to get 300.
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 96000.5733, with a leftover of 0.003.
