12465137 ÷ 487 
Our goal is to divide 12465137 by 487.

Going ahead to step 1:
The number 487 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 487

Step 2:
12 divided by 487 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 487

Let's proceed to step 3:
When dividing 124 by 487, we get 0 with a remainder of 124.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Grab the next digit (6) from the dividend, add it to 124, then carry on: 1246 / 487

On to step 4:
If we divide 1246 by 487, we get 2 and a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 974 from 1246, we get 272.
Fetch the next digit (5) from the dividend, attach it to 272 and continue: 2725 / 487

Step 5:
487 can be fit into 2725 5 times, resulting in a remainder of 290.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 290 after subtracting 2435 from 2725.
Fetch the next digit (1) from the dividend, attach it to 290 and continue: 2901 / 487

Advancing to step 6:
2901 divided by 487 is 5 with a remainder of 466.
The number 5 becomes the next digit in our result. 
Result so far: 255.0
Deduct 2435 from 2901 and we're left with 466.
Append the next digit (3) from the dividend to 466 and continue with: 4663 / 487

Let's proceed to step 7:
487 goes into 4663 9 times with a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 2559.0
Subtract 4383 from 4663 to get 280.
Append the next digit (7) from the dividend to 280 and continue with: 2807 / 487

Let's proceed to step 8:
If we divide 2807 by 487, we get 5 and a remainder of 372.
The number 5 becomes the next digit in our result. 
Result so far: 25595.0
Subtracting 2435 from 2807 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 9:
If we divide 3720 by 487, we get 7 and a remainder of 311.
Write down 7 as next digit of the result. 
Result so far: 25595.7
Subtracting 3409 from 3720 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 10:
If we divide 3110 by 487, we get 6 and a remainder of 188.
The next digit of our result is 6. 
Result so far: 25595.76
Subtracting 2922 from 3110 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 11:
When dividing 1880 by 487, we get 3 with a remainder of 419.
The number 3 becomes the next digit in our result. 
Result so far: 25595.763
If we subtract 1461 from 1880, we get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Advancing to step 12:
The number 487 fits into 4190 8 times, leaving a remainder of 294.
The next digit of our result is 8. 
Result so far: 25595.7638
Subtract 3896 from 4190 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Step 13:
487 goes into 2940 6 times with a remainder of 18.
The next digit of our result is 6. 
Result so far: 25595.76386
Subtracting 2922 from 2940 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
180 divided by 487 is 0 with a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 25595.76386
The remainder is 180 after subtracting 0 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 15:
If we divide 1800 by 487, we get 3 and a remainder of 339.
The number 3 becomes the next digit in our result. 
Result so far: 25595.7638603
The remainder is 339 after subtracting 1461 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 16:
The number 487 fits into 3390 6 times, leaving a remainder of 468.
Record the quotient 6 as the next digit in the result. 
Result so far: 25595.76386036
Subtracting 2922 from 3390 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

The final outcome is 25595.76386036, with a leftover of 4.68e-07.
