89450564 ÷ 394 
Our goal is to divide 89450564 by 394.

On to step 1:
8 divided by 394 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 394

Advancing to step 2:
89 divided by 394 is 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (4) from the dividend, attach it to 89 and continue: 894 / 394

Going ahead to step 3:
394 goes into 894 2 times with a remainder of 106.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 788 from 894, we get 106.
Include the next digit (5) from the dividend after 106, then repeat: 1065 / 394

Going ahead to step 4:
The number 394 fits into 1065 2 times, leaving a remainder of 277.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtract 788 from 1065 to get 277.
Include the next digit (0) from the dividend after 277, then repeat: 2770 / 394

Moving on to step 5:
The number 394 fits into 2770 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 227.0
If we take 2758 away from 2770, we end up with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 394

Moving on to step 6:
If we divide 125 by 394, we get 0 and a remainder of 125.
Put 0 as the next digit of the answer. 
Result so far: 2270.0
If we take 0 away from 125, we end up with 125.
Include the next digit (6) from the dividend after 125, then repeat: 1256 / 394

Going ahead to step 7:
394 goes into 1256 3 times with a remainder of 74.
Write down 3 as next digit of the result. 
Result so far: 22703.0
If we take 1182 away from 1256, we end up with 74.
Append the next digit (4) from the dividend to 74 and continue with: 744 / 394

Step 8:
744 divided by 394 is 1 with a remainder of 350.
Record the quotient 1 as the next digit in the result. 
Result so far: 227031.0
The remainder is 350 after subtracting 394 from 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 9:
When dividing 3500 by 394, we get 8 with a remainder of 348.
Use 8 as the next digit of our solution. 
Result so far: 227031.8
If we subtract 3152 from 3500, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 10:
394 can be fit into 3480 8 times, resulting in a remainder of 328.
The number 8 becomes the next digit in our result. 
Result so far: 227031.88
Subtracting 3152 from 3480 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

After the division, we end up with 227031.88 and a remainder of 0.328.
