We look at the division of 815276 by 78 
Let's see how many times 78 fits into 815276.

Moving on to step 1:
8 divided by 78 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 78

Step 2:
78 can be fit into 81 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 78 from 81, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 78

On to step 3:
35 divided by 78 is 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 35, we get 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 78

Moving on to step 4:
The number 78 fits into 352 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 104.0
If we subtract 312 from 352, we get 40.
Append the next digit (7) from the dividend to 40 and continue with: 407 / 78

Moving on to step 5:
78 goes into 407 5 times with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 1045.0
Subtract 390 from 407 to get 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 78

Going ahead to step 6:
If we divide 176 by 78, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 10452.0
Deduct 156 from 176 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 10452.2
The remainder is 44 after subtracting 156 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
78 goes into 440 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 10452.25
If we subtract 390 from 440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
78 goes into 500 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 10452.256
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 10452.2564
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 10452.25641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
78 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10452.25641
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
If we divide 200 by 78, we get 2 and a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 10452.2564102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 10452.25641025
Subtracting 390 from 440 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 10452.25641025 with a remainder of 5e-08.
