Let's divide 80142325 by 318
Our goal is to divide 80142325 by 318.

Step 1:
8 divided by 318 is 0 with 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.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 318

Let's proceed to step 2:
The number 318 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 318

Advancing to step 3:
If we divide 801 by 318, we get 2 and a remainder of 165.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 636 from 801 leaves us with 165.
Grab the next digit (4) from the dividend, add it to 165, then carry on: 1654 / 318

Step 4:
When dividing 1654 by 318, we get 5 with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 1590 from 1654 leaves us with 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 318

On to step 5:
318 goes into 642 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
Deduct 636 from 642 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 318

Going ahead to step 6:
If we divide 63 by 318, we get 0 and a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 2520.0
The remainder is 63 after subtracting 0 from 63.
Fetch the next digit (2) from the dividend, attach it to 63 and continue: 632 / 318

On to step 7:
When dividing 632 by 318, we get 1 with a remainder of 314.
The next digit of our result is 1. 
Result so far: 25201.0
Subtracting 318 from 632 leaves us with 314.
Bring next digit (5) of the dividend behind the 314 and repeat the process: 3145 / 318

Moving on to step 8:
318 can be fit into 3145 9 times, resulting in a remainder of 283.
Use 9 as the next digit of our solution. 
Result so far: 252019.0
Deduct 2862 from 3145 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 9:
The number 318 fits into 2830 8 times, leaving a remainder of 286.
Put 8 as the next digit of the answer. 
Result so far: 252019.8
If we take 2544 away from 2830, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 10:
If we divide 2860 by 318, we get 8 and a remainder of 316.
Write down 8 as next digit of the result. 
Result so far: 252019.88
If we subtract 2544 from 2860, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

The final result is 252019.88 with a remainder of 0.316.
