We divide 215999 by 64
We want to divide 215999 by 64.

Going ahead to step 1:
If we divide 2 by 64, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 64

Advancing to step 2:
21 divided by 64 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 64

Step 3:
The number 64 fits into 215 3 times, leaving a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 23 after subtracting 192 from 215.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 64

Let's proceed to step 4:
239 divided by 64 is 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 192 from 239, we get 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 64

Moving on to step 5:
64 can be fit into 479 7 times, resulting in a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 337.0
If we take 448 away from 479, we end up with 31.
Take the next digit (9) from the dividend and append it to 31, then repeat: 319 / 64

Going ahead to step 6:
319 divided by 64 is 4 with a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 3374.0
Subtracting 256 from 319 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
When dividing 630 by 64, we get 9 with a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 3374.9
Deduct 576 from 630 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 8:
The number 64 fits into 540 8 times, leaving a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 3374.98
Subtract 512 from 540 to 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.

Going ahead to step 9:
The number 64 fits into 280 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 3374.984
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.

Going ahead to step 10:
If we divide 240 by 64, we get 3 and a remainder of 48.
Write down 3 as next digit of the result. 
Result so far: 3374.9843
If we take 192 away from 240, we end up 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.

Going ahead to step 11:
If we divide 480 by 64, we get 7 and a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 3374.98437
If we subtract 448 from 480, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
64 goes into 320 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3374.984375
Subtracting 320 from 320 leaves us 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 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3374.984375
Deduct 0 from 0 and we're left 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.

Step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3374.984375
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 3374.984375, and the remainder is 0.0.
