Let's divide 80171680 by 918
Our goal is to divide 80171680 by 918.

Moving on to step 1:
8 divided by 918 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 918

Advancing to step 2:
918 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (1) from the dividend and append it to 80, then repeat: 801 / 918

On to step 3:
918 can be fit into 801 0 times, resulting in a remainder of 801.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 801 to get 801.
Include the next digit (7) from the dividend after 801, then repeat: 8017 / 918

On to step 4:
When dividing 8017 by 918, we get 8 with a remainder of 673.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 673 after subtracting 7344 from 8017.
Fetch the next digit (1) from the dividend, attach it to 673 and continue: 6731 / 918

Let's proceed to step 5:
6731 divided by 918 is 7 with a remainder of 305.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Subtracting 6426 from 6731 leaves us with 305.
Fetch the next digit (6) from the dividend, attach it to 305 and continue: 3056 / 918

Moving on to step 6:
If we divide 3056 by 918, we get 3 and a remainder of 302.
The next digit of our result is 3. 
Result so far: 873.0
The remainder is 302 after subtracting 2754 from 3056.
Grab the next digit (8) from the dividend, add it to 302, then carry on: 3028 / 918

Step 7:
918 goes into 3028 3 times with a remainder of 274.
Use 3 as the next digit of our solution. 
Result so far: 8733.0
The remainder is 274 after subtracting 2754 from 3028.
Include the next digit (0) from the dividend after 274, then repeat: 2740 / 918

Moving on to step 8:
2740 divided by 918 is 2 with a remainder of 904.
Write down 2 as next digit of the result. 
Result so far: 87332.0
If we take 1836 away from 2740, we end up with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Moving on to step 9:
If we divide 9040 by 918, we get 9 and a remainder of 778.
Write down 9 as next digit of the result. 
Result so far: 87332.9
Deduct 8262 from 9040 and we're left with 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Going ahead to step 10:
The number 918 fits into 7780 8 times, leaving a remainder of 436.
Use 8 as the next digit of our solution. 
Result so far: 87332.98
If we subtract 7344 from 7780, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Advancing to step 11:
When dividing 4360 by 918, we get 4 with a remainder of 688.
Record the quotient 4 as the next digit in the result. 
Result so far: 87332.984
Deduct 3672 from 4360 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 12:
6880 divided by 918 is 7 with a remainder of 454.
The next digit of our result is 7. 
Result so far: 87332.9847
The remainder is 454 after subtracting 6426 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 13:
918 can be fit into 4540 4 times, resulting in a remainder of 868.
The number 4 becomes the next digit in our result. 
Result so far: 87332.98474
If we subtract 3672 from 4540, we get 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Moving on to step 14:
918 can be fit into 8680 9 times, resulting in a remainder of 418.
Write down 9 as next digit of the result. 
Result so far: 87332.984749
Subtract 8262 from 8680 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 15:
The number 918 fits into 4180 4 times, leaving a remainder of 508.
Put 4 as the next digit of the answer. 
Result so far: 87332.9847494
The remainder is 508 after subtracting 3672 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 16:
The number 918 fits into 5080 5 times, leaving a remainder of 490.
The next digit of our result is 5. 
Result so far: 87332.98474945
Subtracting 4590 from 5080 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

In conclusion, the division gives 87332.98474945 with a balance of 4.9e-07.
