81115125 ÷ 418 
Our goal is to divide 81115125 by 418.

Let's proceed to step 1:
418 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 418

Going ahead to step 2:
418 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 418

Advancing to step 3:
The number 418 fits into 811 1 times, leaving a remainder of 393.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 418 from 811 leaves us with 393.
Grab the next digit (1) from the dividend, add it to 393, then carry on: 3931 / 418

Moving on to step 4:
The number 418 fits into 3931 9 times, leaving a remainder of 169.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 169 after subtracting 3762 from 3931.
Fetch the next digit (5) from the dividend, attach it to 169 and continue: 1695 / 418

Moving on to step 5:
If we divide 1695 by 418, we get 4 and a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 194.0
If we take 1672 away from 1695, we end up with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 418

Step 6:
The number 418 fits into 231 0 times, leaving a remainder of 231.
Put 0 as the next digit of the answer. 
Result so far: 1940.0
Deduct 0 from 231 and we're left with 231.
Take the next digit (2) from the dividend and append it to 231, then repeat: 2312 / 418

Going ahead to step 7:
2312 divided by 418 is 5 with a remainder of 222.
Use 5 as the next digit of our solution. 
Result so far: 19405.0
Subtract 2090 from 2312 to get 222.
Take the next digit (5) from the dividend and append it to 222, then repeat: 2225 / 418

Going ahead to step 8:
418 goes into 2225 5 times with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 194055.0
The remainder is 135 after subtracting 2090 from 2225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
If we divide 1350 by 418, we get 3 and a remainder of 96.
Put 3 as the next digit of the answer. 
Result so far: 194055.3
Subtract 1254 from 1350 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 10:
418 can be fit into 960 2 times, resulting in a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 194055.32
If we subtract 836 from 960, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
418 goes into 1240 2 times with a remainder of 404.
Put 2 as the next digit of the answer. 
Result so far: 194055.322
If we take 836 away from 1240, we end up with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

After the division, we end up with 194055.322 and a remainder of 0.0404.
