249143 divided by 51 
Our goal is to divide 249143 by 51.

Let's proceed to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 51

Step 2:
51 goes into 24 0 times with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Grab the next digit (9) from the dividend, add it to 24, then carry on: 249 / 51

Going ahead to step 3:
249 divided by 51 is 4 with a remainder of 45.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 204 from 249, we get 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 51

Let's proceed to step 4:
When dividing 451 by 51, we get 8 with a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we subtract 408 from 451, we get 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 51

Going ahead to step 5:
The number 51 fits into 434 8 times, leaving a remainder of 26.
The next digit of our result is 8. 
Result so far: 488.0
If we subtract 408 from 434, we get 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 51

Advancing to step 6:
263 divided by 51 is 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 4885.0
Deduct 255 from 263 and we're left with 8.
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 7:
If we divide 80 by 51, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 4885.1
The remainder is 29 after subtracting 51 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
290 divided by 51 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4885.15
If we subtract 255 from 290, we 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.

Advancing to step 9:
When dividing 350 by 51, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 4885.156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
If we divide 440 by 51, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 4885.1568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
When dividing 320 by 51, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 4885.15686
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
If we divide 140 by 51, we get 2 and a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 4885.156862
The remainder is 38 after subtracting 102 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
If we divide 380 by 51, we get 7 and a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 4885.1568627
Deduct 357 from 380 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 14:
230 divided by 51 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4885.15686274
Subtracting 204 from 230 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 4885.15686274 with a balance of 2.6e-08.
