We divide 879845 by 12
The aim is to understand the frequency of 12 in 879845.

Step 1:
8 divided by 12 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 12

Going ahead to step 2:
12 can be fit into 87 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 3 after subtracting 84 from 87.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 12

On to step 3:
If we divide 39 by 12, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we subtract 36 from 39, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 12

Step 4:
12 goes into 38 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 733.0
If we subtract 36 from 38, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 12

Moving on to step 5:
12 can be fit into 24 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 7332.0
Subtract 24 from 24 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 12

Going ahead to step 6:
12 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 73320.0
Subtract 0 from 5 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
12 goes into 50 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 73320.4
Deduct 48 from 50 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
12 goes into 20 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 73320.41
If we take 12 away from 20, we end up 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.

Moving on to step 9:
80 divided by 12 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 73320.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 73320.4166
Deduct 72 from 80 and we're left 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.

After the division, we end up with 73320.4166 and a remainder of 8e-05.
