We're dividing 81389111 by 319 
We want to divide 81389111 by 319.

Step 1:
8 divided by 319 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 319

Let's proceed to step 2:
319 can be fit into 81 0 times, resulting in 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 (3) from the dividend, add it to 81, then carry on: 813 / 319

Moving on to step 3:
319 goes into 813 2 times with a remainder of 175.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 175 after subtracting 638 from 813.
Append the next digit (8) from the dividend to 175 and continue with: 1758 / 319

Moving on to step 4:
If we divide 1758 by 319, we get 5 and a remainder of 163.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Deduct 1595 from 1758 and we're left with 163.
Take the next digit (9) from the dividend and append it to 163, then repeat: 1639 / 319

On to step 5:
319 can be fit into 1639 5 times, resulting in a remainder of 44.
Use 5 as the next digit of our solution. 
Result so far: 255.0
The remainder is 44 after subtracting 1595 from 1639.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 319

Going ahead to step 6:
The number 319 fits into 441 1 times, leaving a remainder of 122.
The next digit of our result is 1. 
Result so far: 2551.0
If we subtract 319 from 441, we get 122.
Take the next digit (1) from the dividend and append it to 122, then repeat: 1221 / 319

Let's proceed to step 7:
319 can be fit into 1221 3 times, resulting in a remainder of 264.
Use 3 as the next digit of our solution. 
Result so far: 25513.0
The remainder is 264 after subtracting 957 from 1221.
Include the next digit (1) from the dividend after 264, then repeat: 2641 / 319

Moving on to step 8:
2641 divided by 319 is 8 with a remainder of 89.
The number 8 becomes the next digit in our result. 
Result so far: 255138.0
If we subtract 2552 from 2641, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 9:
When dividing 890 by 319, we get 2 with a remainder of 252.
Record the quotient 2 as the next digit in the result. 
Result so far: 255138.2
Deduct 638 from 890 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 10:
319 goes into 2520 7 times with a remainder of 287.
Put 7 as the next digit of the answer. 
Result so far: 255138.27
Subtract 2233 from 2520 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 11:
The number 319 fits into 2870 8 times, leaving a remainder of 318.
The next digit of our result is 8. 
Result so far: 255138.278
The remainder is 318 after subtracting 2552 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 12:
319 can be fit into 3180 9 times, resulting in a remainder of 309.
Use 9 as the next digit of our solution. 
Result so far: 255138.2789
If we take 2871 away from 3180, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Advancing to step 13:
The number 319 fits into 3090 9 times, leaving a remainder of 219.
Use 9 as the next digit of our solution. 
Result so far: 255138.27899
If we subtract 2871 from 3090, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Our division results in 255138.27899 with a remaining 0.000219.
