We're dividing 989900 by 78 
Let's see how many times 78 fits into 989900.

Step 1:
78 can be fit into 9 0 times, resulting in 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.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 78

Moving on to step 2:
98 divided by 78 is 1 with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 78 from 98 to get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 78

Step 3:
If we divide 209 by 78, we get 2 and a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 156 from 209 to get 53.
Grab the next digit (9) from the dividend, add it to 53, then carry on: 539 / 78

On to step 4:
78 can be fit into 539 6 times, resulting in a remainder of 71.
The next digit of our result is 6. 
Result so far: 126.0
Subtract 468 from 539 to get 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 78

Let's proceed to step 5:
The number 78 fits into 710 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 1269.0
Deduct 702 from 710 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 78

On to step 6:
The number 78 fits into 80 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 12691.0
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12691.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
78 goes into 200 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12691.02
Deduct 156 from 200 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
When dividing 440 by 78, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 12691.025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
500 divided by 78 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 12691.0256
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
78 goes into 320 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 12691.02564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
If we divide 80 by 78, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 12691.025641
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12691.025641
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
If we divide 200 by 78, we get 2 and a remainder of 44.
The next digit of our result is 2. 
Result so far: 12691.02564102
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 12691.02564102 and a remainder of 4.4e-08.
