We look at the division of 979878 by 23 
We want to figure out the number of times 979878 can be divided by 23.

Step 1:
When dividing 9 by 23, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 23

Moving on to step 2:
If we divide 97 by 23, we get 4 and a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 92 from 97 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 23

Going ahead to step 3:
When dividing 59 by 23, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 46 from 59 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 23

Going ahead to step 4:
The number 23 fits into 138 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 426.0
Subtracting 138 from 138 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 23

Going ahead to step 5:
The number 23 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 4260.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 23

Going ahead to step 6:
23 goes into 78 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 42603.0
Deduct 69 from 78 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
If we divide 90 by 23, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 42603.3
The remainder is 21 after subtracting 69 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
When dividing 210 by 23, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 42603.39
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
30 divided by 23 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 42603.391
If we subtract 23 from 30, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
When dividing 70 by 23, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 42603.3913
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
23 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 42603.3913
If we subtract 0 from 10, 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.

Advancing to step 12:
100 divided by 23 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 42603.391304
Subtracting 92 from 100 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 13:
80 divided by 23 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 42603.3913043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 42603.39130434
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 42603.39130434 with a remainder of 1.8e-08.
