Let's divide 30255019 by 251
We want to divide 30255019 by 251.

Step 1:
When dividing 3 by 251, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 251

Step 2:
30 divided by 251 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 251

Going ahead to step 3:
The number 251 fits into 302 1 times, leaving a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 251 from 302, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 251

Advancing to step 4:
251 goes into 515 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 13 after subtracting 502 from 515.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 251

Step 5:
When dividing 135 by 251, we get 0 with a remainder of 135.
The next digit of our result is 0. 
Result so far: 120.0
The remainder is 135 after subtracting 0 from 135.
Grab the next digit (0) from the dividend, add it to 135, then carry on: 1350 / 251

Going ahead to step 6:
1350 divided by 251 is 5 with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 1205.0
Subtract 1255 from 1350 to get 95.
Bring next digit (1) of the dividend behind the 95 and repeat the process: 951 / 251

Moving on to step 7:
251 goes into 951 3 times with a remainder of 198.
Use 3 as the next digit of our solution. 
Result so far: 12053.0
The remainder is 198 after subtracting 753 from 951.
Grab the next digit (9) from the dividend, add it to 198, then carry on: 1989 / 251

Moving on to step 8:
When dividing 1989 by 251, we get 7 with a remainder of 232.
Put 7 as the next digit of the answer. 
Result so far: 120537.0
If we take 1757 away from 1989, we end up with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 9:
If we divide 2320 by 251, we get 9 and a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 120537.9
The remainder is 61 after subtracting 2259 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 10:
When dividing 610 by 251, we get 2 with a remainder of 108.
The next digit of our result is 2. 
Result so far: 120537.92
If we take 502 away from 610, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 11:
251 can be fit into 1080 4 times, resulting in a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 120537.924
Deduct 1004 from 1080 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
251 can be fit into 760 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 120537.9243
Subtracting 753 from 760 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
70 divided by 251 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 120537.9243
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
The number 251 fits into 700 2 times, leaving a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 120537.924302
If we take 502 away from 700, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 15:
251 goes into 1980 7 times with a remainder of 223.
Use 7 as the next digit of our solution. 
Result so far: 120537.9243027
Subtract 1757 from 1980 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 16:
251 goes into 2230 8 times with a remainder of 222.
The number 8 becomes the next digit in our result. 
Result so far: 120537.92430278
Subtract 2008 from 2230 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The final result is 120537.92430278 with a remainder of 2.22e-07.
