We divide 81201718 by 154
Let's see how many times 154 fits into 81201718.

Going ahead to step 1:
154 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 154

On to step 2:
If we divide 81 by 154, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 154

Advancing to step 3:
If we divide 812 by 154, we get 5 and a remainder of 42.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 770 from 812 to get 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 154

On to step 4:
The number 154 fits into 420 2 times, leaving a remainder of 112.
Write down 2 as next digit of the result. 
Result so far: 52.0
Subtract 308 from 420 to get 112.
Append the next digit (1) from the dividend to 112 and continue with: 1121 / 154

Moving on to step 5:
When dividing 1121 by 154, we get 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 527.0
If we take 1078 away from 1121, we end up with 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 154

Let's proceed to step 6:
154 can be fit into 437 2 times, resulting in a remainder of 129.
The next digit of our result is 2. 
Result so far: 5272.0
If we subtract 308 from 437, we get 129.
Take the next digit (1) from the dividend and append it to 129, then repeat: 1291 / 154

Step 7:
154 can be fit into 1291 8 times, resulting in a remainder of 59.
The next digit of our result is 8. 
Result so far: 52728.0
If we take 1232 away from 1291, we end up with 59.
Append the next digit (8) from the dividend to 59 and continue with: 598 / 154

Step 8:
154 goes into 598 3 times with a remainder of 136.
Use 3 as the next digit of our solution. 
Result so far: 527283.0
The remainder is 136 after subtracting 462 from 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 9:
If we divide 1360 by 154, we get 8 and a remainder of 128.
Put 8 as the next digit of the answer. 
Result so far: 527283.8
Subtracting 1232 from 1360 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 10:
When dividing 1280 by 154, we get 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 527283.88
Subtracting 1232 from 1280 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 527283.88, with a leftover of 0.048.
