Let's divide 998072 by 78
We're looking to find how many times 78 goes into 998072.

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
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 78

On to step 2:
78 can be fit into 99 1 times, resulting in a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 78 from 99, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 78

Going ahead to step 3:
218 divided by 78 is 2 with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 156 from 218 leaves us with 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 78

Step 4:
78 can be fit into 620 7 times, resulting in a remainder of 74.
The next digit of our result is 7. 
Result so far: 127.0
Deduct 546 from 620 and we're left with 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 78

Going ahead to step 5:
78 can be fit into 747 9 times, resulting in a remainder of 45.
The next digit of our result is 9. 
Result so far: 1279.0
If we take 702 away from 747, we end up with 45.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 78

Going ahead to step 6:
452 divided by 78 is 5 with a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 12795.0
The remainder is 62 after subtracting 390 from 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 7:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 12795.7
If we subtract 546 from 620, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 8:
78 can be fit into 740 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 12795.79
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 9:
The number 78 fits into 380 4 times, leaving a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 12795.794
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
When dividing 680 by 78, we get 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 12795.7948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 12795.79487
Subtract 546 from 560 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
When dividing 140 by 78, we get 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 12795.794871
Subtract 78 from 140 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 13:
If we divide 620 by 78, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 12795.7948717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 14:
If we divide 740 by 78, we get 9 and a remainder of 38.
The next digit of our result is 9. 
Result so far: 12795.79487179
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 12795.79487179, and the remainder is 3.8e-08.
