51839539 ÷ 248 
Our goal is to divide 51839539 by 248.

Step 1:
248 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 248

Going ahead to step 2:
248 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 248

On to step 3:
If we divide 518 by 248, we get 2 and a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 496 from 518 leaves us with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 248

On to step 4:
223 divided by 248 is 0 with a remainder of 223.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 223 to get 223.
Take the next digit (9) from the dividend and append it to 223, then repeat: 2239 / 248

Step 5:
2239 divided by 248 is 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
Subtract 2232 from 2239 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 248

Advancing to step 6:
If we divide 75 by 248, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 2090.0
If we subtract 0 from 75, we get 75.
Include the next digit (3) from the dividend after 75, then repeat: 753 / 248

Step 7:
248 goes into 753 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 20903.0
If we take 744 away from 753, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 248

Going ahead to step 8:
The number 248 fits into 99 0 times, leaving a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 209030.0
The remainder is 99 after subtracting 0 from 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 9:
When dividing 990 by 248, we get 3 with a remainder of 246.
Use 3 as the next digit of our solution. 
Result so far: 209030.3
Subtract 744 from 990 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 10:
248 can be fit into 2460 9 times, resulting in a remainder of 228.
Use 9 as the next digit of our solution. 
Result so far: 209030.39
If we subtract 2232 from 2460, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 11:
248 goes into 2280 9 times with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 209030.399
Deduct 2232 from 2280 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 209030.399 with a balance of 0.0048.
