We divide 12257880 by 251
We're looking to find how many times 251 goes into 12257880.

Moving on to step 1:
When dividing 1 by 251, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 251

Advancing to step 2:
12 divided by 251 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 251

Moving on to step 3:
251 can be fit into 122 0 times, resulting in a remainder of 122.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 122 leaves us with 122.
Append the next digit (5) from the dividend to 122 and continue with: 1225 / 251

Going ahead to step 4:
When dividing 1225 by 251, we get 4 with a remainder of 221.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 221 after subtracting 1004 from 1225.
Append the next digit (7) from the dividend to 221 and continue with: 2217 / 251

On to step 5:
When dividing 2217 by 251, we get 8 with a remainder of 209.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we subtract 2008 from 2217, we get 209.
Fetch the next digit (8) from the dividend, attach it to 209 and continue: 2098 / 251

On to step 6:
2098 divided by 251 is 8 with a remainder of 90.
The next digit of our result is 8. 
Result so far: 488.0
If we take 2008 away from 2098, we end up with 90.
Append the next digit (8) from the dividend to 90 and continue with: 908 / 251

On to step 7:
908 divided by 251 is 3 with a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 4883.0
Subtracting 753 from 908 leaves us with 155.
Fetch the next digit (0) from the dividend, attach it to 155 and continue: 1550 / 251

Let's proceed to step 8:
1550 divided by 251 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 48836.0
Deduct 1506 from 1550 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
251 can be fit into 440 1 times, resulting in a remainder of 189.
The number 1 becomes the next digit in our result. 
Result so far: 48836.1
Deduct 251 from 440 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 10:
When dividing 1890 by 251, we get 7 with a remainder of 133.
Use 7 as the next digit of our solution. 
Result so far: 48836.17
Subtracting 1757 from 1890 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 11:
When dividing 1330 by 251, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 48836.175
The remainder is 75 after subtracting 1255 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 12:
251 goes into 750 2 times with a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 48836.1752
Subtract 502 from 750 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 13:
251 can be fit into 2480 9 times, resulting in a remainder of 221.
Record the quotient 9 as the next digit in the result. 
Result so far: 48836.17529
Subtract 2259 from 2480 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Step 14:
251 can be fit into 2210 8 times, resulting in a remainder of 202.
Use 8 as the next digit of our solution. 
Result so far: 48836.175298
Subtract 2008 from 2210 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 15:
251 goes into 2020 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 48836.1752988
Subtract 2008 from 2020 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 48836.1752988 with a remaining 1.2e-07.
