We divide 20398 by 64
We want to figure out the number of times 20398 can be divided by 64.

On to step 1:
When dividing 2 by 64, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 64

Advancing to step 2:
When dividing 20 by 64, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
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:
If we divide 203 by 64, we get 3 and 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.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 64

On to step 4:
119 divided by 64 is 1 with a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 64 from 119 and we're left with 55.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 64

On to step 5:
When dividing 558 by 64, we get 8 with a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
Deduct 512 from 558 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 6:
The number 64 fits into 460 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 318.7
If we take 448 away from 460, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 64 is 1 with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 318.71
Subtract 64 from 120 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 8:
64 can be fit into 560 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 318.718
If we take 512 away from 560, 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.

Let's proceed to step 9:
64 can be fit into 480 7 times, resulting in a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 318.7187
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.

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: 318.71875
If we take 320 away from 320, 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.

Step 11:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 318.71875
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.

Advancing to step 12:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 318.71875
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.

Our division results in 318.71875 with a remaining 0.0.
