We're dividing 254310 by 51 
We want to divide 254310 by 51.

Step 1:
When dividing 2 by 51, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 51

Moving on to step 2:
25 divided by 51 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 51

Going ahead to step 3:
51 goes into 254 4 times with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 204 from 254 and we're left with 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 51

Let's proceed to step 4:
If we divide 503 by 51, we get 9 and a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 459 from 503 to get 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 51

Step 5:
441 divided by 51 is 8 with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 498.0
If we subtract 408 from 441, we get 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 51

Step 6:
When dividing 330 by 51, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 4986.0
Subtracting 306 from 330 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
When dividing 240 by 51, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 4986.4
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
360 divided by 51 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 4986.47
If we subtract 357 from 360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 51, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 4986.47
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 51, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 4986.4705
Subtracting 255 from 300 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
The number 51 fits into 450 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 4986.47058
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 12:
If we divide 420 by 51, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 4986.470588
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 4986.470588, with a leftover of 1.2e-06.
