We're dividing 978903 by 78 
Let's see how many times 78 fits into 978903.

Going ahead to step 1:
If we divide 9 by 78, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 78

Advancing to step 2:
97 divided by 78 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 19 after subtracting 78 from 97.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 78

On to step 3:
78 can be fit into 198 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 156 from 198 and we're left with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 78

Going ahead to step 4:
If we divide 429 by 78, we get 5 and a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtracting 390 from 429 leaves us with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 78

Going ahead to step 5:
When dividing 390 by 78, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1255.0
If we subtract 390 from 390, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 78

Advancing to step 6:
78 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 12550.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 78, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 12550.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 78 fits into 300 3 times, leaving a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 12550.03
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
When dividing 660 by 78, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 12550.038
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
360 divided by 78 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 12550.0384
Subtract 312 from 360 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
78 can be fit into 480 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 12550.03846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
78 can be fit into 120 1 times, resulting in a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 12550.038461
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 12550.0384615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
If we divide 300 by 78, we get 3 and a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 12550.03846153
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 12550.03846153, with a leftover of 6.6e-08.
