We're dividing 830431 by 64 
Our goal is to divide 830431 by 64.

On 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
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 64

Let's proceed to step 2:
64 goes into 83 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 64 from 83 and we're left with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 64

Let's proceed to step 3:
64 can be fit into 190 2 times, resulting in a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 128 from 190 to get 62.
Append the next digit (4) from the dividend to 62 and continue with: 624 / 64

Let's proceed to step 4:
The number 64 fits into 624 9 times, leaving a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtracting 576 from 624 leaves us with 48.
Include the next digit (3) from the dividend after 48, then repeat: 483 / 64

Going ahead to step 5:
64 goes into 483 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 1297.0
If we subtract 448 from 483, we get 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 64

Let's proceed to step 6:
If we divide 351 by 64, we get 5 and a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 12975.0
Deduct 320 from 351 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
The number 64 fits into 310 4 times, leaving a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 12975.4
Deduct 256 from 310 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
The number 64 fits into 540 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 12975.48
If we take 512 away from 540, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
If we divide 280 by 64, we get 4 and a remainder of 24.
The next digit of our result is 4. 
Result so far: 12975.484
If we subtract 256 from 280, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
If we divide 240 by 64, we get 3 and a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 12975.4843
If we subtract 192 from 240, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
When dividing 480 by 64, we get 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 12975.48437
Subtracting 448 from 480 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12975.484375
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.

Going ahead to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12975.484375
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.

On to 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: 12975.484375
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.

The final result is 12975.484375 with a remainder of 0.0.
