We look at the division of 19893 by 64 
Let's see how many times 64 fits into 19893.

Moving on to step 1:
1 divided by 64 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 64

On to step 2:
64 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 64

Advancing to step 3:
198 divided by 64 is 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 6 after subtracting 192 from 198.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 64

Step 4:
If we divide 69 by 64, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 64 from 69 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 64

Moving on to step 5:
53 divided by 64 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 310.0
Deduct 0 from 53 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 6:
If we divide 530 by 64, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 310.8
If we take 512 away from 530, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
64 can be fit into 180 2 times, resulting in a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 310.82
If we subtract 128 from 180, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
64 can be fit into 520 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 310.828
Deduct 512 from 520 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 64 fits into 80 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 310.8281
Subtracting 64 from 80 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
160 divided by 64 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 310.82812
Deduct 128 from 160 and we're left 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.

Let's proceed to step 11:
320 divided by 64 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 310.828125
Deduct 320 from 320 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.

On to step 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 310.828125
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.

Going ahead to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 310.828125
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.

The quotient of the division is 310.828125, and the remainder is 0.0.
