We're dividing 78457831 by 78 
We want to divide 78457831 by 78.

Advancing to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 78

Moving on to step 2:
When dividing 78 by 78, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 78 from 78, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 78

Advancing to step 3:
If we divide 4 by 78, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 78

On to step 4:
45 divided by 78 is 0 with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 78

Step 5:
When dividing 457 by 78, we get 5 with a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 1005.0
Deduct 390 from 457 and we're left with 67.
Bring next digit (8) of the dividend behind the 67 and repeat the process: 678 / 78

On to step 6:
678 divided by 78 is 8 with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 10058.0
If we subtract 624 from 678, we get 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 78

Advancing to step 7:
If we divide 543 by 78, we get 6 and a remainder of 75.
Put 6 as the next digit of the answer. 
Result so far: 100586.0
Deduct 468 from 543 and we're left with 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 78

Moving on to step 8:
78 can be fit into 751 9 times, resulting in a remainder of 49.
The next digit of our result is 9. 
Result so far: 1005869.0
Deduct 702 from 751 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 9:
If we divide 490 by 78, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 1005869.6
Subtract 468 from 490 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
If we divide 220 by 78, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 1005869.62
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
78 can be fit into 640 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 1005869.628
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1005869.6282
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
When dividing 40 by 78, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1005869.6282
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
78 goes into 400 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 1005869.628205
Subtract 390 from 400 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
100 divided by 78 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1005869.6282051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 16:
When dividing 220 by 78, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 1005869.62820512
Subtracting 156 from 220 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 1005869.62820512 with a balance of 6.4e-08.
