We look at the division of 15375 by 64 
We want to figure out the number of times 15375 can be divided by 64.

Step 1:
The number 64 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 64

On to step 2:
64 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 64

Advancing to step 3:
If we divide 153 by 64, we get 2 and a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 128 away from 153, we end up with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 64

Going ahead to step 4:
If we divide 257 by 64, we get 4 and a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 256 from 257 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 64

On to step 5:
The number 64 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 240.0
The remainder is 15 after subtracting 0 from 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 6:
When dividing 150 by 64, we get 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 240.2
Subtracting 128 from 150 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
64 can be fit into 220 3 times, resulting in a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 240.23
If we subtract 192 from 220, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
If we divide 280 by 64, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 240.234
If we take 256 away from 280, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
The number 64 fits into 240 3 times, leaving a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 240.2343
Subtracting 192 from 240 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
When dividing 480 by 64, we get 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 240.23437
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
320 divided by 64 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 240.234375
The remainder is 0 after subtracting 320 from 320.
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 12:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 240.234375
Subtract 0 from 0 to 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.

On to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 240.234375
The remainder is 0 after subtracting 0 from 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 240.234375 and a remainder of 0.0.
