245239 ÷ 51 
We're looking to find how many times 51 goes into 245239.

On to 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
Subtract 0 from 2 to get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 51

Step 2:
51 goes into 24 0 times with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 51

Moving on to step 3:
51 goes into 245 4 times with a remainder of 41.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 41 after subtracting 204 from 245.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 51

Let's proceed to step 4:
51 goes into 412 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Deduct 408 from 412 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 51

Going ahead to step 5:
43 divided by 51 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 480.0
If we take 0 away from 43, we end up with 43.
Append the next digit (9) from the dividend to 43 and continue with: 439 / 51

Moving on to step 6:
If we divide 439 by 51, we get 8 and a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 4808.0
Deduct 408 from 439 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
When dividing 310 by 51, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 4808.6
If we take 306 away from 310, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
40 divided by 51 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4808.6
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 51, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 4808.607
Subtract 357 from 400 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
When dividing 430 by 51, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 4808.6078
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
51 goes into 220 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4808.60784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
160 divided by 51 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 4808.607843
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
70 divided by 51 is 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 4808.6078431
Subtracting 51 from 70 leaves us 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.

Advancing to step 14:
51 can be fit into 190 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 4808.60784313
If we subtract 153 from 190, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

In conclusion, the division gives 4808.60784313 with a balance of 3.7e-08.
