We're dividing 81710805 by 254 
We want to figure out the number of times 81710805 can be divided by 254.

Step 1:
When dividing 8 by 254, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 254

Moving on to step 2:
If we divide 81 by 254, we get 0 and a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 254

Going ahead to step 3:
If we divide 817 by 254, we get 3 and a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 762 from 817 to get 55.
Fetch the next digit (1) from the dividend, attach it to 55 and continue: 551 / 254

Moving on to step 4:
The number 254 fits into 551 2 times, leaving a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we take 508 away from 551, we end up with 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 254

Advancing to step 5:
254 goes into 430 1 times with a remainder of 176.
Use 1 as the next digit of our solution. 
Result so far: 321.0
The remainder is 176 after subtracting 254 from 430.
Append the next digit (8) from the dividend to 176 and continue with: 1768 / 254

Let's proceed to step 6:
1768 divided by 254 is 6 with a remainder of 244.
Put 6 as the next digit of the answer. 
Result so far: 3216.0
Deduct 1524 from 1768 and we're left with 244.
Include the next digit (0) from the dividend after 244, then repeat: 2440 / 254

Moving on to step 7:
254 goes into 2440 9 times with a remainder of 154.
Use 9 as the next digit of our solution. 
Result so far: 32169.0
If we subtract 2286 from 2440, we get 154.
Bring next digit (5) of the dividend behind the 154 and repeat the process: 1545 / 254

Advancing to step 8:
The number 254 fits into 1545 6 times, leaving a remainder of 21.
The next digit of our result is 6. 
Result so far: 321696.0
If we take 1524 away from 1545, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
210 divided by 254 is 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 321696.0
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 10:
254 goes into 2100 8 times with a remainder of 68.
The next digit of our result is 8. 
Result so far: 321696.08
Deduct 2032 from 2100 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
254 can be fit into 680 2 times, resulting in a remainder of 172.
Record the quotient 2 as the next digit in the result. 
Result so far: 321696.082
Deduct 508 from 680 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 12:
The number 254 fits into 1720 6 times, leaving a remainder of 196.
Use 6 as the next digit of our solution. 
Result so far: 321696.0826
The remainder is 196 after subtracting 1524 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 13:
254 can be fit into 1960 7 times, resulting in a remainder of 182.
Write down 7 as next digit of the result. 
Result so far: 321696.08267
The remainder is 182 after subtracting 1778 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 14:
The number 254 fits into 1820 7 times, leaving a remainder of 42.
The next digit of our result is 7. 
Result so far: 321696.082677
If we subtract 1778 from 1820, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 321696.082677 with a remainder of 4.2e-06.
