51090963 ÷ 248 
Let's see how many times 248 fits into 51090963.

Moving on to step 1:
5 divided by 248 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 248

Going ahead to step 2:
If we divide 51 by 248, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 248

Step 3:
248 can be fit into 510 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 496 from 510 to get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 248

Step 4:
The number 248 fits into 149 0 times, leaving a remainder of 149.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 149 after subtracting 0 from 149.
Take the next digit (0) from the dividend and append it to 149, then repeat: 1490 / 248

Let's proceed to step 5:
If we divide 1490 by 248, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 206.0
If we take 1488 away from 1490, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 248

Going ahead to step 6:
29 divided by 248 is 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 2060.0
Subtract 0 from 29 to get 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 248

Advancing to step 7:
If we divide 296 by 248, we get 1 and a remainder of 48.
The next digit of our result is 1. 
Result so far: 20601.0
If we take 248 away from 296, we end up with 48.
Append the next digit (3) from the dividend to 48 and continue with: 483 / 248

Going ahead to step 8:
If we divide 483 by 248, we get 1 and a remainder of 235.
The number 1 becomes the next digit in our result. 
Result so far: 206011.0
If we subtract 248 from 483, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 9:
The number 248 fits into 2350 9 times, leaving a remainder of 118.
Record the quotient 9 as the next digit in the result. 
Result so far: 206011.9
The remainder is 118 after subtracting 2232 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 10:
The number 248 fits into 1180 4 times, leaving a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 206011.94
Subtract 992 from 1180 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 11:
When dividing 1880 by 248, we get 7 with a remainder of 144.
Record the quotient 7 as the next digit in the result. 
Result so far: 206011.947
Subtracting 1736 from 1880 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 12:
248 goes into 1440 5 times with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 206011.9475
Deduct 1240 from 1440 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
2000 divided by 248 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 206011.94758
The remainder is 16 after subtracting 1984 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
If we divide 160 by 248, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 206011.94758
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
When dividing 1600 by 248, we get 6 with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 206011.9475806
The remainder is 112 after subtracting 1488 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 16:
248 goes into 1120 4 times with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 206011.94758064
Subtracting 992 from 1120 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

In conclusion, the division gives 206011.94758064 with a balance of 1.28e-07.
