We look at the division of 641364 by 64 
Let's see how many times 64 fits into 641364.

Going ahead to step 1:
If we divide 6 by 64, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 64

On to step 2:
If we divide 64 by 64, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 64 from 64 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 64

On to step 3:
The number 64 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 64

Advancing to step 4:
The number 64 fits into 13 0 times, leaving a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 64

Step 5:
If we divide 136 by 64, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1002.0
The remainder is 8 after subtracting 128 from 136.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 64

On to step 6:
The number 64 fits into 84 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 10021.0
If we take 64 away from 84, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
64 can be fit into 200 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 10021.3
If we subtract 192 from 200, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
64 can be fit into 80 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 10021.31
Subtract 64 from 80 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
160 divided by 64 is 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 10021.312
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.

Moving on to step 10:
If we divide 320 by 64, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10021.3125
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.

On to step 11:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10021.3125
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.

On to step 12:
0 divided by 64 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10021.3125
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.

The quotient of the division is 10021.3125, and the remainder is 0.0.
