254234 ÷ 51 
Our goal is to divide 254234 by 51.

On to 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
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 51

Moving on to step 2:
If we divide 25 by 51, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 51

Moving on to step 3:
When dividing 254 by 51, we get 4 with a remainder of 50.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 204 from 254 to get 50.
Include the next digit (2) from the dividend after 50, then repeat: 502 / 51

Moving on to step 4:
When dividing 502 by 51, we get 9 with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we subtract 459 from 502, we get 43.
Grab the next digit (3) from the dividend, add it to 43, then carry on: 433 / 51

Let's proceed to step 5:
When dividing 433 by 51, we get 8 with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 498.0
The remainder is 25 after subtracting 408 from 433.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 51

Going ahead to step 6:
If we divide 254 by 51, we get 4 and a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 4984.0
Deduct 204 from 254 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.

Step 7:
The number 51 fits into 500 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 4984.9
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.

Let's proceed to step 8:
If we divide 410 by 51, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 4984.98
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.

Moving on to step 9:
51 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4984.98
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 10:
When dividing 200 by 51, we get 3 with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 4984.9803
If we take 153 away from 200, we end up with 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 11:
If we divide 470 by 51, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 4984.98039
If we take 459 away from 470, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
51 goes into 110 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 4984.980392
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.

Moving on to step 13:
80 divided by 51 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 4984.9803921
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 14:
When dividing 290 by 51, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 4984.98039215
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 4984.98039215 with a remainder of 3.5e-08.
