We look at the division of 321010 by 51 
We want to figure out the number of times 321010 can be divided by 51.

Going ahead to step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 51

On to step 2:
The number 51 fits into 32 0 times, leaving a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 51

Advancing to step 3:
If we divide 321 by 51, we get 6 and a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 15 after subtracting 306 from 321.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 51

On to step 4:
150 divided by 51 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Subtract 102 from 150 to get 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 51

Moving on to step 5:
51 goes into 481 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 629.0
The remainder is 22 after subtracting 459 from 481.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 51

Moving on to step 6:
220 divided by 51 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 6294.0
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 51 fits into 160 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 6294.3
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
If we divide 70 by 51, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 6294.31
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
51 goes into 190 3 times with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 6294.313
If we take 153 away from 190, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 10:
370 divided by 51 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 6294.3137
Deduct 357 from 370 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
51 goes into 130 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 6294.31372
Subtracting 102 from 130 leaves us 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 12:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 6294.313725
If we subtract 255 from 280, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 13:
If we divide 250 by 51, we get 4 and a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 6294.3137254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
If we divide 460 by 51, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 6294.31372549
Subtracting 459 from 460 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 6294.31372549 with a remainder of 1e-09.
