We're dividing 990883 by 78 
Our goal is to divide 990883 by 78.

Advancing to step 1:
When dividing 9 by 78, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 78

Advancing to step 2:
78 goes into 99 1 times with 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.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 78

On to step 3:
If we divide 210 by 78, we get 2 and a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 156 from 210 and we're left with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 78

Moving on to step 4:
The number 78 fits into 548 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 127.0
The remainder is 2 after subtracting 546 from 548.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 78

Going ahead to step 5:
78 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 1270.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (3) from the dividend and append it to 28, then repeat: 283 / 78

Going ahead to step 6:
78 goes into 283 3 times with a remainder of 49.
The next digit of our result is 3. 
Result so far: 12703.0
Deduct 234 from 283 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
78 can be fit into 490 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 12703.6
If we subtract 468 from 490, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
220 divided by 78 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 12703.62
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.

Going ahead to step 9:
78 can be fit into 640 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 12703.628
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 10:
If we divide 160 by 78, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 12703.6282
If we take 156 away from 160, we end up with 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 11:
When dividing 40 by 78, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12703.6282
If we take 0 away from 40, we end up 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.

On to step 12:
When dividing 400 by 78, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 12703.628205
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
When dividing 100 by 78, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 12703.6282051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
When dividing 220 by 78, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 12703.62820512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 12703.62820512, with a leftover of 6.4e-08.
