We're dividing 78087654 by 900 
We're looking to find how many times 900 goes into 78087654.

On to step 1:
The number 900 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 900

On to step 2:
The number 900 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 900

Moving on to step 3:
If we divide 780 by 900, we get 0 and a remainder of 780.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 780 leaves us with 780.
Bring next digit (8) of the dividend behind the 780 and repeat the process: 7808 / 900

Moving on to step 4:
The number 900 fits into 7808 8 times, leaving a remainder of 608.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7200 from 7808 to get 608.
Take the next digit (7) from the dividend and append it to 608, then repeat: 6087 / 900

Advancing to step 5:
When dividing 6087 by 900, we get 6 with a remainder of 687.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 5400 from 6087 and we're left with 687.
Take the next digit (6) from the dividend and append it to 687, then repeat: 6876 / 900

Moving on to step 6:
900 goes into 6876 7 times with a remainder of 576.
Put 7 as the next digit of the answer. 
Result so far: 867.0
Subtracting 6300 from 6876 leaves us with 576.
Fetch the next digit (5) from the dividend, attach it to 576 and continue: 5765 / 900

Moving on to step 7:
900 goes into 5765 6 times with a remainder of 365.
Put 6 as the next digit of the answer. 
Result so far: 8676.0
Deduct 5400 from 5765 and we're left with 365.
Fetch the next digit (4) from the dividend, attach it to 365 and continue: 3654 / 900

Step 8:
900 can be fit into 3654 4 times, resulting in a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 86764.0
Deduct 3600 from 3654 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 9:
The number 900 fits into 540 0 times, leaving a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 86764.0
Subtracting 0 from 540 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 10:
When dividing 5400 by 900, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 86764.06
Subtracting 5400 from 5400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 900 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 86764.06
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
900 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 86764.06
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 86764.06, with a leftover of 0.0.
