Let's divide 64392025 by 578
Our goal is to divide 64392025 by 578.

On to step 1:
578 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 578

Going ahead to step 2:
The number 578 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 578

Let's proceed to step 3:
578 can be fit into 643 1 times, resulting in a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 578 from 643, we get 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 578

Let's proceed to step 4:
659 divided by 578 is 1 with a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 578 away from 659, we end up with 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 578

Step 5:
When dividing 812 by 578, we get 1 with a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 111.0
The remainder is 234 after subtracting 578 from 812.
Append the next digit (0) from the dividend to 234 and continue with: 2340 / 578

Going ahead to step 6:
578 can be fit into 2340 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 1114.0
Subtracting 2312 from 2340 leaves us with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 578

On to step 7:
578 goes into 282 0 times with a remainder of 282.
Record the quotient 0 as the next digit in the result. 
Result so far: 11140.0
If we take 0 away from 282, we end up with 282.
Bring next digit (5) of the dividend behind the 282 and repeat the process: 2825 / 578

Advancing to step 8:
If we divide 2825 by 578, we get 4 and a remainder of 513.
The next digit of our result is 4. 
Result so far: 111404.0
Subtract 2312 from 2825 to get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Advancing to step 9:
5130 divided by 578 is 8 with a remainder of 506.
Write down 8 as next digit of the result. 
Result so far: 111404.8
Subtracting 4624 from 5130 leaves us with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Moving on to step 10:
When dividing 5060 by 578, we get 8 with a remainder of 436.
Put 8 as the next digit of the answer. 
Result so far: 111404.88
Subtracting 4624 from 5060 leaves us with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

The quotient of the division is 111404.88, and the remainder is 0.436.
