856019 ÷ 78 
We want to figure out the number of times 856019 can be divided by 78.

On to step 1:
8 divided by 78 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 78

Let's proceed to step 2:
85 divided by 78 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 78 from 85 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 78

On to step 3:
The number 78 fits into 76 0 times, leaving a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 78

Let's proceed to step 4:
78 goes into 760 9 times with a remainder of 58.
Write down 9 as next digit of the result. 
Result so far: 109.0
Subtracting 702 from 760 leaves us with 58.
Grab the next digit (1) from the dividend, add it to 58, then carry on: 581 / 78

Going ahead to step 5:
78 goes into 581 7 times with a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 1097.0
If we take 546 away from 581, we end up with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 78

On to step 6:
78 goes into 359 4 times with a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 10974.0
Deduct 312 from 359 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
The number 78 fits into 470 6 times, leaving a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 10974.6
Subtracting 468 from 470 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.

On to step 8:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10974.6
Subtracting 0 from 20 leaves us 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.

Step 9:
200 divided by 78 is 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 10974.602
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.

Moving on to step 10:
When dividing 440 by 78, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 10974.6025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 10974.60256
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.

Going ahead to step 12:
If we divide 320 by 78, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 10974.602564
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 13:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 10974.6025641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10974.6025641
Subtracting 0 from 20 leaves us 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.

Our division results in 10974.6025641 with a remaining 2e-08.
