78257934 ÷ 254 
Our goal is to divide 78257934 by 254.

Let's proceed to step 1:
254 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 254

Step 2:
When dividing 78 by 254, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 254

On to step 3:
254 goes into 782 3 times with a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 762 from 782 leaves us with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 254

Advancing to step 4:
254 can be fit into 205 0 times, resulting in a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we subtract 0 from 205, we get 205.
Take the next digit (7) from the dividend and append it to 205, then repeat: 2057 / 254

Going ahead to step 5:
If we divide 2057 by 254, we get 8 and a remainder of 25.
The next digit of our result is 8. 
Result so far: 308.0
If we take 2032 away from 2057, we end up with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 254

On to step 6:
If we divide 259 by 254, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 3081.0
Subtract 254 from 259 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 254

Step 7:
254 goes into 53 0 times with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 30810.0
If we take 0 away from 53, we end up with 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 254

Going ahead to step 8:
254 can be fit into 534 2 times, resulting in a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 308102.0
The remainder is 26 after subtracting 508 from 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
If we divide 260 by 254, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 308102.1
Subtracting 254 from 260 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 254 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 308102.1
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
254 can be fit into 600 2 times, resulting in a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 308102.102
Subtracting 508 from 600 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 12:
254 goes into 920 3 times with a remainder of 158.
Write down 3 as next digit of the result. 
Result so far: 308102.1023
If we subtract 762 from 920, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 13:
254 can be fit into 1580 6 times, resulting in a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 308102.10236
Deduct 1524 from 1580 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
254 can be fit into 560 2 times, resulting in a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 308102.102362
If we subtract 508 from 560, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 15:
If we divide 520 by 254, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 308102.1023622
Subtract 508 from 520 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 308102.1023622, and the remainder is 1.2e-07.
