We divide 251960 by 51
We want to divide 251960 by 51.

Step 1:
2 divided by 51 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 51

On to step 2:
If we divide 25 by 51, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 51

Step 3:
251 divided by 51 is 4 with a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 47 after subtracting 204 from 251.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 51

Let's proceed to step 4:
479 divided by 51 is 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 459 from 479 to get 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 51

On to step 5:
51 goes into 206 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 494.0
Subtract 204 from 206 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 51

Going ahead to step 6:
51 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4940.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
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: 4940.3
The remainder is 47 after subtracting 153 from 200.
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 8:
51 goes into 470 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 4940.39
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
If we divide 110 by 51, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 4940.392
Deduct 102 from 110 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.

Advancing to step 10:
51 goes into 80 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 4940.3921
If we take 51 away from 80, we end up 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 11:
When dividing 290 by 51, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 4940.39215
The remainder is 35 after subtracting 255 from 290.
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 12:
350 divided by 51 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 4940.392156
Subtract 306 from 350 to 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.

Step 13:
If we divide 440 by 51, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 4940.3921568
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
51 can be fit into 320 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 4940.39215686
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.

In conclusion, the division gives 4940.39215686 with a balance of 1.4e-08.
