We're dividing 813237 by 64 
We want to figure out the number of times 813237 can be divided by 64.

Going ahead to step 1:
64 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 64

Moving on to step 2:
The number 64 fits into 81 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 64 away from 81, we end up with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 64

On to step 3:
The number 64 fits into 173 2 times, leaving a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 128 from 173 to get 45.
Fetch the next digit (2) from the dividend, attach it to 45 and continue: 452 / 64

On to step 4:
64 goes into 452 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we subtract 448 from 452, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 64

Advancing to step 5:
64 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 1270.0
Subtract 0 from 43 to get 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 64

Going ahead to step 6:
64 can be fit into 437 6 times, resulting in a remainder of 53.
The next digit of our result is 6. 
Result so far: 12706.0
Subtracting 384 from 437 leaves us 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.

Advancing to step 7:
64 goes into 530 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 12706.8
Subtracting 512 from 530 leaves us 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.

Let's proceed to step 8:
64 goes into 180 2 times with a remainder of 52.
The next digit of our result is 2. 
Result so far: 12706.82
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.

Advancing to step 9:
When dividing 520 by 64, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 12706.828
If we take 512 away from 520, we end up 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.

Step 10:
64 can be fit into 80 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 12706.8281
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.

Let's proceed to step 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 12706.82812
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12706.828125
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12706.828125
If we subtract 0 from 0, we 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.

On to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12706.828125
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.

After the division, we end up with 12706.828125 and a remainder of 0.0.
