Let's divide 998953 by 78
We want to figure out the number of times 998953 can be divided by 78.

Advancing to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 78

Advancing to step 2:
If we divide 99 by 78, we get 1 and a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 21 after subtracting 78 from 99.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 78

On to step 3:
78 can be fit into 218 2 times, resulting in a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 62 after subtracting 156 from 218.
Include the next digit (9) from the dividend after 62, then repeat: 629 / 78

Moving on to step 4:
If we divide 629 by 78, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
If we subtract 624 from 629, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 78

Moving on to step 5:
55 divided by 78 is 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 1280.0
The remainder is 55 after subtracting 0 from 55.
Include the next digit (3) from the dividend after 55, then repeat: 553 / 78

Step 6:
If we divide 553 by 78, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 12807.0
If we take 546 away from 553, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 78 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 12807.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
The number 78 fits into 700 8 times, leaving a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 12807.08
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
760 divided by 78 is 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 12807.089
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
The number 78 fits into 580 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 12807.0897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
If we divide 340 by 78, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 12807.08974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
78 goes into 280 3 times with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 12807.089743
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 12807.0897435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 14:
When dividing 700 by 78, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 12807.08974358
Subtract 624 from 700 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 12807.08974358 with a remainder of 7.6e-08.
