78387854 divided by 514 
Let's see how many times 514 fits into 78387854.

Moving on to step 1:
The number 514 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 514

Step 2:
The number 514 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 514

Advancing to step 3:
783 divided by 514 is 1 with a remainder of 269.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 514 from 783 and we're left with 269.
Append the next digit (8) from the dividend to 269 and continue with: 2698 / 514

Step 4:
When dividing 2698 by 514, we get 5 with a remainder of 128.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 2570 away from 2698, we end up with 128.
Bring next digit (7) of the dividend behind the 128 and repeat the process: 1287 / 514

Let's proceed to step 5:
514 can be fit into 1287 2 times, resulting in a remainder of 259.
The next digit of our result is 2. 
Result so far: 152.0
If we subtract 1028 from 1287, we get 259.
Append the next digit (8) from the dividend to 259 and continue with: 2598 / 514

Moving on to step 6:
When dividing 2598 by 514, we get 5 with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 1525.0
Subtracting 2570 from 2598 leaves us with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 514

Advancing to step 7:
If we divide 285 by 514, we get 0 and a remainder of 285.
The number 0 becomes the next digit in our result. 
Result so far: 15250.0
Deduct 0 from 285 and we're left with 285.
Grab the next digit (4) from the dividend, add it to 285, then carry on: 2854 / 514

Let's proceed to step 8:
514 goes into 2854 5 times with a remainder of 284.
Use 5 as the next digit of our solution. 
Result so far: 152505.0
Subtracting 2570 from 2854 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 9:
If we divide 2840 by 514, we get 5 and a remainder of 270.
The next digit of our result is 5. 
Result so far: 152505.5
Subtract 2570 from 2840 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
514 goes into 2700 5 times with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 152505.55
Deduct 2570 from 2700 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The quotient of the division is 152505.55, and the remainder is 0.13.
