Let's divide 12649289 by 511
We want to divide 12649289 by 511.

Going ahead to step 1:
The number 511 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 511

Let's proceed to step 2:
When dividing 12 by 511, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 511

Let's proceed to step 3:
If we divide 126 by 511, we get 0 and a remainder of 126.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 126, we get 126.
Append the next digit (4) from the dividend to 126 and continue with: 1264 / 511

On to step 4:
511 can be fit into 1264 2 times, resulting in a remainder of 242.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1022 from 1264 to get 242.
Append the next digit (9) from the dividend to 242 and continue with: 2429 / 511

Step 5:
511 goes into 2429 4 times with a remainder of 385.
Write down 4 as next digit of the result. 
Result so far: 24.0
The remainder is 385 after subtracting 2044 from 2429.
Grab the next digit (2) from the dividend, add it to 385, then carry on: 3852 / 511

Step 6:
511 can be fit into 3852 7 times, resulting in a remainder of 275.
Put 7 as the next digit of the answer. 
Result so far: 247.0
Deduct 3577 from 3852 and we're left with 275.
Grab the next digit (8) from the dividend, add it to 275, then carry on: 2758 / 511

Step 7:
2758 divided by 511 is 5 with a remainder of 203.
The next digit of our result is 5. 
Result so far: 2475.0
If we subtract 2555 from 2758, we get 203.
Append the next digit (9) from the dividend to 203 and continue with: 2039 / 511

On to step 8:
If we divide 2039 by 511, we get 3 and a remainder of 506.
Put 3 as the next digit of the answer. 
Result so far: 24753.0
If we take 1533 away from 2039, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 9:
5060 divided by 511 is 9 with a remainder of 461.
Write down 9 as next digit of the result. 
Result so far: 24753.9
If we take 4599 away from 5060, we end up with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Let's proceed to step 10:
When dividing 4610 by 511, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 24753.99
Deduct 4599 from 4610 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 24753.99, with a leftover of 0.011.
