We're dividing 81913790 by 593 
Our goal is to divide 81913790 by 593.

Advancing to step 1:
The number 593 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 593

Step 2:
When dividing 81 by 593, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Grab the next digit (9) from the dividend, add it to 81, then carry on: 819 / 593

Going ahead to step 3:
If we divide 819 by 593, we get 1 and a remainder of 226.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 593 from 819 leaves us with 226.
Take the next digit (1) from the dividend and append it to 226, then repeat: 2261 / 593

On to step 4:
When dividing 2261 by 593, we get 3 with a remainder of 482.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1779 from 2261 leaves us with 482.
Bring next digit (3) of the dividend behind the 482 and repeat the process: 4823 / 593

Let's proceed to step 5:
If we divide 4823 by 593, we get 8 and a remainder of 79.
The next digit of our result is 8. 
Result so far: 138.0
Deduct 4744 from 4823 and we're left with 79.
Bring next digit (7) of the dividend behind the 79 and repeat the process: 797 / 593

Step 6:
The number 593 fits into 797 1 times, leaving a remainder of 204.
Put 1 as the next digit of the answer. 
Result so far: 1381.0
If we subtract 593 from 797, we get 204.
Fetch the next digit (9) from the dividend, attach it to 204 and continue: 2049 / 593

Advancing to step 7:
2049 divided by 593 is 3 with a remainder of 270.
The number 3 becomes the next digit in our result. 
Result so far: 13813.0
If we take 1779 away from 2049, we end up with 270.
Grab the next digit (0) from the dividend, add it to 270, then carry on: 2700 / 593

Let's proceed to step 8:
2700 divided by 593 is 4 with a remainder of 328.
Record the quotient 4 as the next digit in the result. 
Result so far: 138134.0
Subtracting 2372 from 2700 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 9:
The number 593 fits into 3280 5 times, leaving a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 138134.5
If we subtract 2965 from 3280, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 10:
When dividing 3150 by 593, we get 5 with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 138134.55
Subtract 2965 from 3150 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

The final outcome is 138134.55, with a leftover of 0.185.
