We're dividing 64503506 by 64 
We want to divide 64503506 by 64.

On to step 1:
The number 64 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 64

Let's proceed to step 2:
64 can be fit into 64 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 64 from 64.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 64

Let's proceed to step 3:
5 divided by 64 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 64

Advancing to step 4:
64 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 50 leaves us with 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 64

Advancing to step 5:
64 goes into 503 7 times with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 1007.0
Subtracting 448 from 503 leaves us with 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 64

Advancing to step 6:
64 can be fit into 555 8 times, resulting in a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 10078.0
Subtract 512 from 555 to get 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 64

Moving on to step 7:
When dividing 430 by 64, we get 6 with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 100786.0
Subtract 384 from 430 to get 46.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 64

Going ahead to step 8:
64 can be fit into 466 7 times, resulting in a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 1007867.0
If we take 448 away from 466, 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.

Advancing to step 9:
The number 64 fits into 180 2 times, leaving a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 1007867.2
Subtracting 128 from 180 leaves us with 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 10:
If we divide 520 by 64, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1007867.28
If we subtract 512 from 520, 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.

On to step 11:
80 divided by 64 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1007867.281
If we take 64 away from 80, we end up 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 12:
64 goes into 160 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 1007867.2812
Subtract 128 from 160 to 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.

Going ahead to step 13:
When dividing 320 by 64, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1007867.28125
Subtract 320 from 320 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.

Step 14:
0 divided by 64 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1007867.28125
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.

On to step 15:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1007867.28125
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.

In conclusion, the division gives 1007867.28125 with a balance of 0.0.
