87178786 ÷ 254 
Our goal is to divide 87178786 by 254.

Let's proceed to step 1:
If we divide 8 by 254, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 254

Going ahead to step 2:
254 can be fit into 87 0 times, resulting in a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 254

Let's proceed to step 3:
When dividing 871 by 254, we get 3 with a remainder of 109.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 762 from 871 and we're left with 109.
Bring next digit (7) of the dividend behind the 109 and repeat the process: 1097 / 254

Going ahead to step 4:
When dividing 1097 by 254, we get 4 with a remainder of 81.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 1016 from 1097, we get 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 254

Moving on to step 5:
254 can be fit into 818 3 times, resulting in a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 343.0
The remainder is 56 after subtracting 762 from 818.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 254

Let's proceed to step 6:
254 can be fit into 567 2 times, resulting in a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 3432.0
Deduct 508 from 567 and we're left with 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 254

Let's proceed to step 7:
If we divide 598 by 254, we get 2 and a remainder of 90.
The next digit of our result is 2. 
Result so far: 34322.0
Deduct 508 from 598 and we're left with 90.
Append the next digit (6) from the dividend to 90 and continue with: 906 / 254

Step 8:
254 goes into 906 3 times with a remainder of 144.
Write down 3 as next digit of the result. 
Result so far: 343223.0
If we take 762 away from 906, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 9:
The number 254 fits into 1440 5 times, leaving a remainder of 170.
Record the quotient 5 as the next digit in the result. 
Result so far: 343223.5
If we subtract 1270 from 1440, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
The number 254 fits into 1700 6 times, leaving a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 343223.56
If we take 1524 away from 1700, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
254 can be fit into 1760 6 times, resulting in a remainder of 236.
Put 6 as the next digit of the answer. 
Result so far: 343223.566
If we take 1524 away from 1760, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

After the division, we end up with 343223.566 and a remainder of 0.0236.
