We're dividing 388640 by 32 
We want to figure out the number of times 388640 can be divided by 32.

Let's proceed to step 1:
If we divide 3 by 32, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 32

On to step 2:
The number 32 fits into 38 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 32 from 38 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 32

On to step 3:
68 divided by 32 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 4 after subtracting 64 from 68.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 32

Moving on to step 4:
If we divide 46 by 32, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 121.0
If we take 32 away from 46, we end up with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 32

Step 5:
144 divided by 32 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1214.0
If we subtract 128 from 144, we get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 32

Advancing to step 6:
If we divide 160 by 32, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12145.0
The remainder is 0 after subtracting 160 from 160.
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 7:
If we divide 0 by 32, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12145.0
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.

Let's proceed to step 8:
32 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12145.0
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.

After the division, we end up with 12145.0 and a remainder of 0.0.
