Let's divide 12009500 by 578
Let's see how many times 578 fits into 12009500.

Going ahead to step 1:
The number 578 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 578

On to step 2:
578 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 578

Advancing to step 3:
The number 578 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 120 leaves us with 120.
Bring next digit (0) of the dividend behind the 120 and repeat the process: 1200 / 578

Advancing to step 4:
1200 divided by 578 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1156 from 1200 and we're left with 44.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 578

Moving on to step 5:
If we divide 449 by 578, we get 0 and a remainder of 449.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 449, we get 449.
Grab the next digit (5) from the dividend, add it to 449, then carry on: 4495 / 578

Going ahead to step 6:
The number 578 fits into 4495 7 times, leaving a remainder of 449.
The next digit of our result is 7. 
Result so far: 207.0
If we take 4046 away from 4495, we end up with 449.
Fetch the next digit (0) from the dividend, attach it to 449 and continue: 4490 / 578

Moving on to step 7:
If we divide 4490 by 578, we get 7 and a remainder of 444.
The next digit of our result is 7. 
Result so far: 2077.0
Subtract 4046 from 4490 to get 444.
Include the next digit (0) from the dividend after 444, then repeat: 4440 / 578

On to step 8:
4440 divided by 578 is 7 with a remainder of 394.
Write down 7 as next digit of the result. 
Result so far: 20777.0
Subtract 4046 from 4440 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 9:
The number 578 fits into 3940 6 times, leaving a remainder of 472.
The next digit of our result is 6. 
Result so far: 20777.6
Deduct 3468 from 3940 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 10:
578 can be fit into 4720 8 times, resulting in a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 20777.68
The remainder is 96 after subtracting 4624 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 11:
578 can be fit into 960 1 times, resulting in a remainder of 382.
Write down 1 as next digit of the result. 
Result so far: 20777.681
Subtracting 578 from 960 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 12:
The number 578 fits into 3820 6 times, leaving a remainder of 352.
The next digit of our result is 6. 
Result so far: 20777.6816
Subtracting 3468 from 3820 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 13:
If we divide 3520 by 578, we get 6 and a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 20777.68166
If we take 3468 away from 3520, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 20777.68166 with a balance of 5.2e-05.
