We look at the division of 1270643 by 494 
Our goal is to divide 1270643 by 494.

Step 1:
When dividing 1 by 494, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 494

On to step 2:
494 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 494

Let's proceed to step 3:
The number 494 fits into 127 0 times, leaving a remainder of 127.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 127, we end up with 127.
Take the next digit (0) from the dividend and append it to 127, then repeat: 1270 / 494

Advancing to step 4:
494 goes into 1270 2 times with a remainder of 282.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 988 away from 1270, we end up with 282.
Bring next digit (6) of the dividend behind the 282 and repeat the process: 2826 / 494

Step 5:
When dividing 2826 by 494, we get 5 with a remainder of 356.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 2470 from 2826 leaves us with 356.
Append the next digit (4) from the dividend to 356 and continue with: 3564 / 494

Moving on to step 6:
The number 494 fits into 3564 7 times, leaving a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
Deduct 3458 from 3564 and we're left with 106.
Take the next digit (3) from the dividend and append it to 106, then repeat: 1063 / 494

Step 7:
1063 divided by 494 is 2 with a remainder of 75.
The number 2 becomes the next digit in our result. 
Result so far: 2572.0
Subtracting 988 from 1063 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 8:
The number 494 fits into 750 1 times, leaving a remainder of 256.
Record the quotient 1 as the next digit in the result. 
Result so far: 2572.1
Subtracting 494 from 750 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 9:
494 goes into 2560 5 times with a remainder of 90.
The next digit of our result is 5. 
Result so far: 2572.15
If we subtract 2470 from 2560, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
900 divided by 494 is 1 with a remainder of 406.
The next digit of our result is 1. 
Result so far: 2572.151
If we take 494 away from 900, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 11:
If we divide 4060 by 494, we get 8 and a remainder of 108.
The next digit of our result is 8. 
Result so far: 2572.1518
Subtracting 3952 from 4060 leaves us 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.

Let's proceed to step 12:
494 goes into 1080 2 times with a remainder of 92.
The next digit of our result is 2. 
Result so far: 2572.15182
If we take 988 away from 1080, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 13:
When dividing 920 by 494, we get 1 with a remainder of 426.
Write down 1 as next digit of the result. 
Result so far: 2572.151821
Subtract 494 from 920 to get 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Step 14:
When dividing 4260 by 494, we get 8 with a remainder of 308.
The next digit of our result is 8. 
Result so far: 2572.1518218
If we take 3952 away from 4260, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 15:
If we divide 3080 by 494, we get 6 and a remainder of 116.
Write down 6 as next digit of the result. 
Result so far: 2572.15182186
If we subtract 2964 from 3080, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final outcome is 2572.15182186, with a leftover of 1.16e-07.
