We're dividing 998893 by 78 
We want to divide 998893 by 78.

Step 1:
The number 78 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 78

Moving on to step 2:
99 divided by 78 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 78 from 99 to get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 78

Let's proceed to step 3:
When dividing 218 by 78, we get 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 156 from 218 leaves us with 62.
Take the next digit (8) from the dividend and append it to 62, then repeat: 628 / 78

Advancing to step 4:
If we divide 628 by 78, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we subtract 624 from 628, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 78

Let's proceed to step 5:
If we divide 49 by 78, we get 0 and a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 1280.0
If we subtract 0 from 49, we get 49.
Append the next digit (3) from the dividend to 49 and continue with: 493 / 78

Moving on to step 6:
The number 78 fits into 493 6 times, leaving a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 12806.0
If we take 468 away from 493, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
78 can be fit into 250 3 times, resulting in a remainder of 16.
The next digit of our result is 3. 
Result so far: 12806.3
Subtracting 234 from 250 leaves us 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:
78 can be fit into 160 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 12806.32
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 78, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 12806.32
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 78, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 12806.3205
Deduct 390 from 400 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.

Advancing to step 11:
When dividing 100 by 78, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 12806.32051
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.

On to step 12:
220 divided by 78 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 12806.320512
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
78 goes into 640 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 12806.3205128
The remainder is 16 after subtracting 624 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
160 divided by 78 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 12806.32051282
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.

The final outcome is 12806.32051282, with a leftover of 4e-09.
