We're dividing 86422535 by 593 
Our goal is to divide 86422535 by 593.

On to step 1:
593 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 593

Moving on to step 2:
593 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 593

Going ahead to step 3:
When dividing 864 by 593, we get 1 with a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 593 from 864, we get 271.
Take the next digit (2) from the dividend and append it to 271, then repeat: 2712 / 593

Let's proceed to step 4:
593 goes into 2712 4 times with a remainder of 340.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 2372 from 2712, we get 340.
Include the next digit (2) from the dividend after 340, then repeat: 3402 / 593

Let's proceed to step 5:
When dividing 3402 by 593, we get 5 with a remainder of 437.
Write down 5 as next digit of the result. 
Result so far: 145.0
Deduct 2965 from 3402 and we're left with 437.
Grab the next digit (5) from the dividend, add it to 437, then carry on: 4375 / 593

Step 6:
593 can be fit into 4375 7 times, resulting in a remainder of 224.
Write down 7 as next digit of the result. 
Result so far: 1457.0
If we take 4151 away from 4375, we end up with 224.
Bring next digit (3) of the dividend behind the 224 and repeat the process: 2243 / 593

Moving on to step 7:
When dividing 2243 by 593, we get 3 with a remainder of 464.
Record the quotient 3 as the next digit in the result. 
Result so far: 14573.0
The remainder is 464 after subtracting 1779 from 2243.
Take the next digit (5) from the dividend and append it to 464, then repeat: 4645 / 593

Advancing to step 8:
593 goes into 4645 7 times with a remainder of 494.
The next digit of our result is 7. 
Result so far: 145737.0
If we take 4151 away from 4645, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Moving on to step 9:
If we divide 4940 by 593, we get 8 and a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 145737.8
Deduct 4744 from 4940 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 10:
If we divide 1960 by 593, we get 3 and a remainder of 181.
Write down 3 as next digit of the result. 
Result so far: 145737.83
If we subtract 1779 from 1960, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 11:
1810 divided by 593 is 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 145737.833
The remainder is 31 after subtracting 1779 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 145737.833, with a leftover of 0.0031.
