12661730 divided by 251 
Let's see how many times 251 fits into 12661730.

Moving on to step 1:
The number 251 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 251

Step 2:
When dividing 12 by 251, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 251

Moving on to step 3:
If we divide 126 by 251, we get 0 and a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 126 leaves us with 126.
Bring next digit (6) of the dividend behind the 126 and repeat the process: 1266 / 251

Step 4:
251 can be fit into 1266 5 times, resulting in a remainder of 11.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 1255 from 1266 to get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 251

Going ahead to step 5:
111 divided by 251 is 0 with a remainder of 111.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 111 and we're left with 111.
Grab the next digit (7) from the dividend, add it to 111, then carry on: 1117 / 251

Step 6:
251 can be fit into 1117 4 times, resulting in a remainder of 113.
The next digit of our result is 4. 
Result so far: 504.0
If we subtract 1004 from 1117, we get 113.
Include the next digit (3) from the dividend after 113, then repeat: 1133 / 251

Going ahead to step 7:
251 goes into 1133 4 times with a remainder of 129.
The number 4 becomes the next digit in our result. 
Result so far: 5044.0
Subtracting 1004 from 1133 leaves us with 129.
Grab the next digit (0) from the dividend, add it to 129, then carry on: 1290 / 251

Advancing to step 8:
If we divide 1290 by 251, we get 5 and a remainder of 35.
The next digit of our result is 5. 
Result so far: 50445.0
Subtracting 1255 from 1290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
251 can be fit into 350 1 times, resulting in a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 50445.1
The remainder is 99 after subtracting 251 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 10:
The number 251 fits into 990 3 times, leaving a remainder of 237.
The number 3 becomes the next digit in our result. 
Result so far: 50445.13
Deduct 753 from 990 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 11:
If we divide 2370 by 251, we get 9 and a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 50445.139
Subtracting 2259 from 2370 leaves us with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 12:
When dividing 1110 by 251, we get 4 with a remainder of 106.
The number 4 becomes the next digit in our result. 
Result so far: 50445.1394
The remainder is 106 after subtracting 1004 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 13:
251 goes into 1060 4 times with a remainder of 56.
The next digit of our result is 4. 
Result so far: 50445.13944
Subtract 1004 from 1060 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 50445.13944 and a remainder of 5.6e-05.
