We're dividing 673879 by 51 
Let's see how many times 51 fits into 673879.

Step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 51

Step 2:
The number 51 fits into 67 1 times, leaving a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 67 and we're left with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 51

Let's proceed to step 3:
51 can be fit into 163 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 153 from 163 leaves us with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 51

Let's proceed to step 4:
The number 51 fits into 108 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
The remainder is 6 after subtracting 102 from 108.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 51

Step 5:
The number 51 fits into 67 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1321.0
Deduct 51 from 67 and we're left with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 51

Let's proceed to step 6:
When dividing 169 by 51, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 13213.0
The remainder is 16 after subtracting 153 from 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 13213.3
Deduct 153 from 160 and we're left with 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:
When dividing 70 by 51, we get 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 13213.31
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
The number 51 fits into 190 3 times, leaving a remainder of 37.
The next digit of our result is 3. 
Result so far: 13213.313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
When dividing 370 by 51, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 13213.3137
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.

Step 11:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 13213.31372
If we take 102 away from 130, 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 12:
280 divided by 51 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 13213.313725
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.

Step 13:
250 divided by 51 is 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 13213.3137254
If we take 204 away from 250, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 14:
460 divided by 51 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 13213.31372549
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 13213.31372549 with a remainder of 1e-09.
