We're dividing 998289 by 78 
We want to figure out the number of times 998289 can be divided by 78.

Going ahead to step 1:
78 goes into 9 0 times with 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.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 78

Step 2:
99 divided by 78 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 78 from 99, we get 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 78

Moving on to step 3:
218 divided by 78 is 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.
Bring next digit (2) of the dividend behind the 62 and repeat the process: 622 / 78

On to step 4:
The number 78 fits into 622 7 times, leaving a remainder of 76.
Use 7 as the next digit of our solution. 
Result so far: 127.0
Deduct 546 from 622 and we're left with 76.
Take the next digit (8) from the dividend and append it to 76, then repeat: 768 / 78

Let's proceed to step 5:
78 goes into 768 9 times with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 1279.0
If we take 702 away from 768, we end up with 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 78

Moving on to step 6:
78 goes into 669 8 times with a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 12798.0
If we subtract 624 from 669, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 7:
78 can be fit into 450 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 12798.5
If we subtract 390 from 450, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
78 can be fit into 600 7 times, resulting in a remainder of 54.
The next digit of our result is 7. 
Result so far: 12798.57
Subtracting 546 from 600 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
78 goes into 540 6 times with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 12798.576
If we subtract 468 from 540, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
78 can be fit into 720 9 times, resulting in a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 12798.5769
If we subtract 702 from 720, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
If we divide 180 by 78, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 12798.57692
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
When dividing 240 by 78, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 12798.576923
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
60 divided by 78 is 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 12798.576923
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
78 goes into 600 7 times with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 12798.57692307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 12798.57692307, and the remainder is 5.4e-08.
