We divide 321478 by 51
Let's see how many times 51 fits into 321478.

Step 1:
3 divided by 51 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 51

Step 2:
32 divided by 51 is 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 32, we 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
Deduct 306 from 321 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 51

Advancing to step 4:
51 can be fit into 154 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we subtract 153 from 154, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 51

Let's proceed to step 5:
The number 51 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 630.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 51

Moving on to step 6:
When dividing 178 by 51, we get 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 6303.0
Deduct 153 from 178 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
If we divide 250 by 51, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 6303.4
Subtract 204 from 250 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
The number 51 fits into 460 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 6303.49
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 6303.49
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
If we divide 100 by 51, we get 1 and a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 6303.4901
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 11:
51 goes into 490 9 times with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 6303.49019
Subtract 459 from 490 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 12:
51 can be fit into 310 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6303.490196
Subtract 306 from 310 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
When dividing 40 by 51, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 6303.490196
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
400 divided by 51 is 7 with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 6303.49019607
Subtracting 357 from 400 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final result is 6303.49019607 with a remainder of 4.3e-08.
