Let's divide 85426259 by 518
We want to divide 85426259 by 518.

Going ahead to step 1:
518 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 518

Let's proceed to step 2:
518 goes into 85 0 times with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Append the next digit (4) from the dividend to 85 and continue with: 854 / 518

Going ahead to step 3:
518 goes into 854 1 times with a remainder of 336.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 518 from 854, we get 336.
Bring next digit (2) of the dividend behind the 336 and repeat the process: 3362 / 518

On to step 4:
518 can be fit into 3362 6 times, resulting in a remainder of 254.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 3108 from 3362, we get 254.
Append the next digit (6) from the dividend to 254 and continue with: 2546 / 518

Let's proceed to step 5:
518 goes into 2546 4 times with a remainder of 474.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Subtract 2072 from 2546 to get 474.
Grab the next digit (2) from the dividend, add it to 474, then carry on: 4742 / 518

On to step 6:
When dividing 4742 by 518, we get 9 with a remainder of 80.
The next digit of our result is 9. 
Result so far: 1649.0
Deduct 4662 from 4742 and we're left with 80.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 518

Advancing to step 7:
If we divide 805 by 518, we get 1 and a remainder of 287.
The number 1 becomes the next digit in our result. 
Result so far: 16491.0
The remainder is 287 after subtracting 518 from 805.
Fetch the next digit (9) from the dividend, attach it to 287 and continue: 2879 / 518

Advancing to step 8:
518 goes into 2879 5 times with a remainder of 289.
The next digit of our result is 5. 
Result so far: 164915.0
The remainder is 289 after subtracting 2590 from 2879.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 9:
When dividing 2890 by 518, we get 5 with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 164915.5
If we subtract 2590 from 2890, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 10:
If we divide 3000 by 518, we get 5 and a remainder of 410.
Write down 5 as next digit of the result. 
Result so far: 164915.55
Deduct 2590 from 3000 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Our division results in 164915.55 with a remaining 0.41.
