848509 divided by 78 
Our goal is to divide 848509 by 78.

Going ahead to step 1:
When dividing 8 by 78, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 78

On to step 2:
The number 78 fits into 84 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 78 from 84 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 78

Going ahead to step 3:
78 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 68 after subtracting 0 from 68.
Bring next digit (5) of the dividend behind the 68 and repeat the process: 685 / 78

Moving on to step 4:
78 can be fit into 685 8 times, resulting in a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 108.0
The remainder is 61 after subtracting 624 from 685.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 78

Let's proceed to step 5:
78 goes into 610 7 times with a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 1087.0
If we subtract 546 from 610, we get 64.
Grab the next digit (9) from the dividend, add it to 64, then carry on: 649 / 78

Advancing to step 6:
When dividing 649 by 78, we get 8 with a remainder of 25.
The number 8 becomes the next digit in our result. 
Result so far: 10878.0
If we subtract 624 from 649, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
When dividing 250 by 78, we get 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 10878.3
Deduct 234 from 250 and we're left 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 8:
160 divided by 78 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 10878.32
Deduct 156 from 160 and we're left 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.

On to step 9:
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: 10878.32
Subtract 0 from 40 to get 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 10:
400 divided by 78 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10878.3205
The remainder is 10 after subtracting 390 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
When dividing 100 by 78, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 10878.32051
Subtract 78 from 100 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 12:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 10878.320512
If we subtract 156 from 220, we get 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 13:
640 divided by 78 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 10878.3205128
If we take 624 away from 640, we end up 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.

Step 14:
160 divided by 78 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 10878.32051282
If we take 156 away from 160, we end up 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.

Our division results in 10878.32051282 with a remaining 4e-09.
