We look at the division of 812109 by 64 
We want to divide 812109 by 64.

Moving on to step 1:
If we divide 8 by 64, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 64

On to step 2:
If we divide 81 by 64, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 17 after subtracting 64 from 81.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 64

Advancing to step 3:
64 can be fit into 172 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 128 from 172, we get 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 64

On to step 4:
64 goes into 441 6 times with a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Deduct 384 from 441 and we're left with 57.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 64

Advancing to step 5:
If we divide 570 by 64, we get 8 and a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 1268.0
If we subtract 512 from 570, we get 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 64

Let's proceed to step 6:
64 goes into 589 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 12689.0
If we subtract 576 from 589, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 64, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 12689.2
Subtracting 128 from 130 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
64 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12689.2
If we take 0 away from 20, 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.

Going ahead to step 9:
When dividing 200 by 64, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 12689.203
The remainder is 8 after subtracting 192 from 200.
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 10:
The number 64 fits into 80 1 times, leaving a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 12689.2031
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.

Let's proceed to step 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 12689.20312
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.

On to step 12:
If we divide 320 by 64, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12689.203125
If we subtract 320 from 320, 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.

Step 13:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12689.203125
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.

Step 14:
64 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12689.203125
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.

In conclusion, the division gives 12689.203125 with a balance of 0.0.
