12939437 divided by 488 
We want to figure out the number of times 12939437 can be divided by 488.

Let's proceed to step 1:
1 divided by 488 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 488

Advancing to step 2:
The number 488 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 488

Step 3:
The number 488 fits into 129 0 times, leaving a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 129 to get 129.
Grab the next digit (3) from the dividend, add it to 129, then carry on: 1293 / 488

On to step 4:
488 can be fit into 1293 2 times, resulting in a remainder of 317.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 976 from 1293, we get 317.
Append the next digit (9) from the dividend to 317 and continue with: 3179 / 488

Step 5:
488 can be fit into 3179 6 times, resulting in a remainder of 251.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 2928 from 3179 to get 251.
Take the next digit (4) from the dividend and append it to 251, then repeat: 2514 / 488

Going ahead to step 6:
When dividing 2514 by 488, we get 5 with a remainder of 74.
The next digit of our result is 5. 
Result so far: 265.0
Subtract 2440 from 2514 to get 74.
Bring next digit (3) of the dividend behind the 74 and repeat the process: 743 / 488

Going ahead to step 7:
488 goes into 743 1 times with a remainder of 255.
Record the quotient 1 as the next digit in the result. 
Result so far: 2651.0
Deduct 488 from 743 and we're left with 255.
Include the next digit (7) from the dividend after 255, then repeat: 2557 / 488

Let's proceed to step 8:
The number 488 fits into 2557 5 times, leaving a remainder of 117.
Use 5 as the next digit of our solution. 
Result so far: 26515.0
Subtracting 2440 from 2557 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 9:
488 goes into 1170 2 times with a remainder of 194.
Put 2 as the next digit of the answer. 
Result so far: 26515.2
If we subtract 976 from 1170, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 10:
1940 divided by 488 is 3 with a remainder of 476.
Use 3 as the next digit of our solution. 
Result so far: 26515.23
Subtract 1464 from 1940 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 11:
When dividing 4760 by 488, we get 9 with a remainder of 368.
Put 9 as the next digit of the answer. 
Result so far: 26515.239
Subtract 4392 from 4760 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 12:
3680 divided by 488 is 7 with a remainder of 264.
Use 7 as the next digit of our solution. 
Result so far: 26515.2397
If we subtract 3416 from 3680, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 13:
488 goes into 2640 5 times with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 26515.23975
Deduct 2440 from 2640 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.

On to step 14:
2000 divided by 488 is 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 26515.239754
Deduct 1952 from 2000 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.

Let's proceed to step 15:
When dividing 480 by 488, we get 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 26515.239754
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 16:
488 goes into 4800 9 times with a remainder of 408.
Put 9 as the next digit of the answer. 
Result so far: 26515.23975409
Subtract 4392 from 4800 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final result is 26515.23975409 with a remainder of 4.08e-07.
