We're dividing 20309510 by 64 
Let's see how many times 64 fits into 20309510.

Let's proceed to step 1:
If we divide 2 by 64, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 64

Going ahead to step 2:
If we divide 20 by 64, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 64

Let's proceed to step 3:
203 divided by 64 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 192 from 203 to get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 64

Advancing to step 4:
If we divide 110 by 64, we get 1 and a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 64 away from 110, we end up with 46.
Include the next digit (9) from the dividend after 46, then repeat: 469 / 64

Let's proceed to step 5:
The number 64 fits into 469 7 times, leaving a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
If we take 448 away from 469, we end up with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 64

Step 6:
64 can be fit into 215 3 times, resulting in a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 3173.0
Subtract 192 from 215 to get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 64

On to step 7:
231 divided by 64 is 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 31733.0
If we subtract 192 from 231, we get 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 64

Moving on to step 8:
The number 64 fits into 390 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 317336.0
The remainder is 6 after subtracting 384 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 64 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 317336.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
When dividing 600 by 64, we get 9 with a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 317336.09
If we take 576 away from 600, 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 11:
64 goes into 240 3 times with a remainder of 48.
The number 3 becomes the next digit in our result. 
Result so far: 317336.093
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.

Moving on to step 12:
64 goes into 480 7 times with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 317336.0937
Subtract 448 from 480 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.

Moving on to step 13:
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: 317336.09375
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.

Step 14:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 317336.09375
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:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 317336.09375
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.

Our division results in 317336.09375 with a remaining 0.0.
