We look at the division of 81128631 by 493 
We want to divide 81128631 by 493.

Let's proceed to step 1:
493 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 493

Moving on to step 2:
The number 493 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 493

Step 3:
When dividing 811 by 493, we get 1 with a remainder of 318.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 493 from 811, we get 318.
Include the next digit (2) from the dividend after 318, then repeat: 3182 / 493

Advancing to step 4:
3182 divided by 493 is 6 with a remainder of 224.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 224 after subtracting 2958 from 3182.
Append the next digit (8) from the dividend to 224 and continue with: 2248 / 493

Moving on to step 5:
2248 divided by 493 is 4 with a remainder of 276.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
If we subtract 1972 from 2248, we get 276.
Take the next digit (6) from the dividend and append it to 276, then repeat: 2766 / 493

On to step 6:
The number 493 fits into 2766 5 times, leaving a remainder of 301.
The next digit of our result is 5. 
Result so far: 1645.0
Subtracting 2465 from 2766 leaves us with 301.
Append the next digit (3) from the dividend to 301 and continue with: 3013 / 493

Let's proceed to step 7:
3013 divided by 493 is 6 with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 16456.0
Subtract 2958 from 3013 to get 55.
Fetch the next digit (1) from the dividend, attach it to 55 and continue: 551 / 493

Going ahead to step 8:
493 goes into 551 1 times with a remainder of 58.
The next digit of our result is 1. 
Result so far: 164561.0
If we subtract 493 from 551, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
493 can be fit into 580 1 times, resulting in a remainder of 87.
The number 1 becomes the next digit in our result. 
Result so far: 164561.1
Subtract 493 from 580 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 10:
493 goes into 870 1 times with a remainder of 377.
Write down 1 as next digit of the result. 
Result so far: 164561.11
Subtract 493 from 870 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Our division results in 164561.11 with a remaining 0.377.
