We look at the division of 988584 by 78 
We want to divide 988584 by 78.

On to step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 78

Moving on to step 2:
When dividing 98 by 78, we get 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 78 from 98, we get 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 78

Step 3:
When dividing 208 by 78, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 52 after subtracting 156 from 208.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 78

Going ahead to step 4:
When dividing 525 by 78, we get 6 with a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
The remainder is 57 after subtracting 468 from 525.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 78

On to step 5:
The number 78 fits into 578 7 times, leaving a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 1267.0
Subtract 546 from 578 to get 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 78

On to step 6:
78 goes into 324 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 12674.0
The remainder is 12 after subtracting 312 from 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
78 goes into 120 1 times with a remainder of 42.
The next digit of our result is 1. 
Result so far: 12674.1
If we take 78 away from 120, we end up with 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 8:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 12674.15
If we take 390 away from 420, we end up 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.

Moving on to step 9:
When dividing 300 by 78, we get 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 12674.153
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.

Moving on to step 10:
78 goes into 660 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 12674.1538
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.

Let's proceed to step 11:
360 divided by 78 is 4 with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 12674.15384
If we subtract 312 from 360, we 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.

Advancing to step 12:
When dividing 480 by 78, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 12674.153846
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.

Going ahead to step 13:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 12674.1538461
Subtract 78 from 120 to 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.

Step 14:
The number 78 fits into 420 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 12674.15384615
Subtract 390 from 420 to 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.

Our division results in 12674.15384615 with a remaining 3e-08.
