We're dividing 599233 by 12 
The aim is to understand the frequency of 12 in 599233.

Moving on to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 12

Going ahead to step 2:
If we divide 59 by 12, we get 4 and a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 48 from 59, we get 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 12

Step 3:
If we divide 119 by 12, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
The remainder is 11 after subtracting 108 from 119.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 12

Going ahead to step 4:
112 divided by 12 is 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 499.0
If we subtract 108 from 112, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

Going ahead to step 5:
43 divided by 12 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 4993.0
Deduct 36 from 43 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 12

Going ahead to step 6:
12 can be fit into 73 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 49936.0
Subtract 72 from 73 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.

On to step 7:
If we divide 10 by 12, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 49936.0
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.

On to step 8:
100 divided by 12 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 49936.08
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 49936.083
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 49936.0833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 49936.0833, with a leftover of 4e-05.
