799978 divided by 78 
Let's see how many times 78 fits into 799978.

Going ahead to step 1:
78 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 78

Moving on to step 2:
If we divide 79 by 78, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 78 from 79 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 78

Moving on to step 3:
When dividing 19 by 78, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 78

Moving on to step 4:
If we divide 199 by 78, we get 2 and a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 102.0
The remainder is 43 after subtracting 156 from 199.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 78

Going ahead to step 5:
78 goes into 437 5 times with a remainder of 47.
The number 5 becomes the next digit in our result. 
Result so far: 1025.0
Subtracting 390 from 437 leaves us with 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 78

Step 6:
78 goes into 478 6 times with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 10256.0
Subtract 468 from 478 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.

Going ahead to step 7:
If we divide 100 by 78, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 10256.1
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
If we divide 220 by 78, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 10256.12
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
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: 10256.128
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
78 goes into 160 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 10256.1282
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
If we divide 40 by 78, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10256.1282
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.

On to step 12:
400 divided by 78 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10256.128205
If we subtract 390 from 400, we 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.

Step 13:
78 goes into 100 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 10256.1282051
Deduct 78 from 100 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
The number 78 fits into 220 2 times, leaving a remainder of 64.
The next digit of our result is 2. 
Result so far: 10256.12820512
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 10256.12820512 with a balance of 6.4e-08.
