We divide 82420638 by 511
Our goal is to divide 82420638 by 511.

Going ahead to step 1:
511 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 511

Let's proceed to step 2:
If we divide 82 by 511, we get 0 and a remainder of 82.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Append the next digit (4) from the dividend to 82 and continue with: 824 / 511

Moving on to step 3:
The number 511 fits into 824 1 times, leaving a remainder of 313.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 511 away from 824, we end up with 313.
Grab the next digit (2) from the dividend, add it to 313, then carry on: 3132 / 511

Step 4:
The number 511 fits into 3132 6 times, leaving a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 3066 from 3132, we get 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 511

Advancing to step 5:
660 divided by 511 is 1 with a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 161.0
Deduct 511 from 660 and we're left with 149.
Include the next digit (6) from the dividend after 149, then repeat: 1496 / 511

Let's proceed to step 6:
511 can be fit into 1496 2 times, resulting in a remainder of 474.
Put 2 as the next digit of the answer. 
Result so far: 1612.0
If we take 1022 away from 1496, we end up with 474.
Fetch the next digit (3) from the dividend, attach it to 474 and continue: 4743 / 511

Going ahead to step 7:
4743 divided by 511 is 9 with a remainder of 144.
The next digit of our result is 9. 
Result so far: 16129.0
Subtracting 4599 from 4743 leaves us with 144.
Append the next digit (8) from the dividend to 144 and continue with: 1448 / 511

On to step 8:
The number 511 fits into 1448 2 times, leaving a remainder of 426.
Record the quotient 2 as the next digit in the result. 
Result so far: 161292.0
The remainder is 426 after subtracting 1022 from 1448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 9:
If we divide 4260 by 511, we get 8 and a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 161292.8
Subtract 4088 from 4260 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 10:
If we divide 1720 by 511, we get 3 and a remainder of 187.
Use 3 as the next digit of our solution. 
Result so far: 161292.83
If we take 1533 away from 1720, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 11:
If we divide 1870 by 511, we get 3 and a remainder of 337.
The number 3 becomes the next digit in our result. 
Result so far: 161292.833
Subtract 1533 from 1870 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

The final outcome is 161292.833, with a leftover of 0.0337.
