We're dividing 786787 by 78 
We want to divide 786787 by 78.

Going ahead to step 1:
7 divided by 78 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 78

Advancing to step 2:
When dividing 78 by 78, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 78 from 78 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 78

Step 3:
The number 78 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 78

Going ahead to step 4:
If we divide 67 by 78, we get 0 and a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 67 and we're left with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 78

Going ahead to step 5:
If we divide 678 by 78, we get 8 and a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 1008.0
The remainder is 54 after subtracting 624 from 678.
Bring next digit (7) of the dividend behind the 54 and repeat the process: 547 / 78

Advancing to step 6:
547 divided by 78 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 10087.0
If we take 546 away from 547, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 78 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10087.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 78 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 10087.01
If we take 78 away from 100, we end up 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.

Step 9:
78 goes into 220 2 times with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 10087.012
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.

Let's proceed to step 10:
When dividing 640 by 78, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 10087.0128
If we subtract 624 from 640, we get 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 11:
If we divide 160 by 78, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 10087.01282
The remainder is 4 after subtracting 156 from 160.
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 12:
78 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10087.01282
The remainder is 40 after subtracting 0 from 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 13:
78 can be fit into 400 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 10087.0128205
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.

Going ahead to step 14:
78 goes into 100 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 10087.01282051
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.

Our division results in 10087.01282051 with a remaining 2.2e-08.
