Let's divide 78559786 by 900
We want to figure out the number of times 78559786 can be divided by 900.

Moving on to step 1:
900 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 900

On to step 2:
If we divide 78 by 900, we get 0 and a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 900

Let's proceed to step 3:
900 goes into 785 0 times with a remainder of 785.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 785 and we're left with 785.
Take the next digit (5) from the dividend and append it to 785, then repeat: 7855 / 900

Advancing to step 4:
When dividing 7855 by 900, we get 8 with a remainder of 655.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7200 from 7855 leaves us with 655.
Append the next digit (9) from the dividend to 655 and continue with: 6559 / 900

Step 5:
900 goes into 6559 7 times with a remainder of 259.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
The remainder is 259 after subtracting 6300 from 6559.
Bring next digit (7) of the dividend behind the 259 and repeat the process: 2597 / 900

On to step 6:
2597 divided by 900 is 2 with a remainder of 797.
The next digit of our result is 2. 
Result so far: 872.0
Subtract 1800 from 2597 to get 797.
Include the next digit (8) from the dividend after 797, then repeat: 7978 / 900

On to step 7:
900 goes into 7978 8 times with a remainder of 778.
The next digit of our result is 8. 
Result so far: 8728.0
Subtract 7200 from 7978 to get 778.
Take the next digit (6) from the dividend and append it to 778, then repeat: 7786 / 900

Advancing to step 8:
7786 divided by 900 is 8 with a remainder of 586.
Use 8 as the next digit of our solution. 
Result so far: 87288.0
If we subtract 7200 from 7786, we get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Going ahead to step 9:
If we divide 5860 by 900, we get 6 and a remainder of 460.
Use 6 as the next digit of our solution. 
Result so far: 87288.6
If we take 5400 away from 5860, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 10:
900 can be fit into 4600 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 87288.65
Subtract 4500 from 4600 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
900 goes into 1000 1 times with a remainder of 100.
Record the quotient 1 as the next digit in the result. 
Result so far: 87288.651
If we subtract 900 from 1000, we get 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:
1000 divided by 900 is 1 with a remainder of 100.
Write down 1 as next digit of the result. 
Result so far: 87288.6511
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.

After the division, we end up with 87288.6511 and a remainder of 0.001.
