We look at the division of 856221 by 78 
Let's see how many times 78 fits into 856221.

Let's proceed to step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 78

Let's proceed to step 2:
When dividing 85 by 78, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 78 from 85 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 78

Step 3:
78 can be fit into 76 0 times, resulting in a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 76 after subtracting 0 from 76.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 78

Step 4:
The number 78 fits into 762 9 times, leaving a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 109.0
If we subtract 702 from 762, we get 60.
Include the next digit (2) from the dividend after 60, then repeat: 602 / 78

Step 5:
The number 78 fits into 602 7 times, leaving a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 1097.0
If we take 546 away from 602, we end up with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 78

Going ahead to step 6:
The number 78 fits into 561 7 times, leaving a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 10977.0
If we subtract 546 from 561, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
78 can be fit into 150 1 times, resulting in a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 10977.1
Subtracting 78 from 150 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
78 goes into 720 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 10977.19
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
78 goes into 180 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 10977.192
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
78 can be fit into 240 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 10977.1923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
When dividing 60 by 78, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10977.1923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
When dividing 600 by 78, we get 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 10977.192307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 13:
78 goes into 540 6 times with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 10977.1923076
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
When dividing 720 by 78, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 10977.19230769
Deduct 702 from 720 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 10977.19230769, and the remainder is 1.8e-08.
