We divide 87336609 by 578
We want to divide 87336609 by 578.

On to step 1:
When dividing 8 by 578, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 578

On to step 2:
When dividing 87 by 578, we get 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Take the next digit (3) from the dividend and append it to 87, then repeat: 873 / 578

On to step 3:
If we divide 873 by 578, we get 1 and a remainder of 295.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 295 after subtracting 578 from 873.
Take the next digit (3) from the dividend and append it to 295, then repeat: 2953 / 578

Step 4:
578 can be fit into 2953 5 times, resulting in a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 2890 from 2953 leaves us with 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 578

On to step 5:
578 can be fit into 636 1 times, resulting in a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
Deduct 578 from 636 and we're left with 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 578

Step 6:
When dividing 586 by 578, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1511.0
If we take 578 away from 586, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 578

Advancing to step 7:
If we divide 80 by 578, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 15110.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 578

Going ahead to step 8:
When dividing 809 by 578, we get 1 with a remainder of 231.
Record the quotient 1 as the next digit in the result. 
Result so far: 151101.0
If we subtract 578 from 809, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 9:
When dividing 2310 by 578, we get 3 with a remainder of 576.
Record the quotient 3 as the next digit in the result. 
Result so far: 151101.3
The remainder is 576 after subtracting 1734 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 10:
When dividing 5760 by 578, we get 9 with a remainder of 558.
Put 9 as the next digit of the answer. 
Result so far: 151101.39
The remainder is 558 after subtracting 5202 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 11:
When dividing 5580 by 578, we get 9 with a remainder of 378.
Put 9 as the next digit of the answer. 
Result so far: 151101.399
The remainder is 378 after subtracting 5202 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

The final result is 151101.399 with a remainder of 0.0378.
