812966 ÷ 51 
We want to figure out the number of times 812966 can be divided by 51.

Let's proceed to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 51

Moving on to step 2:
51 goes into 81 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 30 after subtracting 51 from 81.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 51

Let's proceed to step 3:
When dividing 302 by 51, we get 5 with a remainder of 47.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 255 from 302 to get 47.
Take the next digit (9) from the dividend and append it to 47, then repeat: 479 / 51

Going ahead to step 4:
51 goes into 479 9 times with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
If we take 459 away from 479, we end up with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 51

Let's proceed to step 5:
When dividing 206 by 51, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1594.0
Deduct 204 from 206 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 51

Step 6:
51 goes into 26 0 times with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 15940.0
Deduct 0 from 26 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
The number 51 fits into 260 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 15940.5
Subtracting 255 from 260 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
If we divide 50 by 51, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 15940.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
51 goes into 500 9 times with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 15940.509
The remainder is 41 after subtracting 459 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
If we divide 410 by 51, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 15940.5098
The remainder is 2 after subtracting 408 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
When dividing 20 by 51, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 15940.5098
Subtract 0 from 20 to get 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 12:
If we divide 200 by 51, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 15940.509803
If we subtract 153 from 200, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
470 divided by 51 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 15940.5098039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
110 divided by 51 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 15940.50980392
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 15940.50980392 and a remainder of 8e-09.
