We divide 598786 by 12
The aim is to understand the frequency of 12 in 598786.

On to step 1:
The number 12 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 12

Going ahead to step 2:
If we divide 59 by 12, we get 4 and a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 11 after subtracting 48 from 59.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 12

Let's proceed to step 3:
If we divide 118 by 12, we get 9 and a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 108 from 118 to get 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 12

Moving on to step 4:
When dividing 107 by 12, we get 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 498.0
Subtracting 96 from 107 leaves us with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 12

Advancing to step 5:
The number 12 fits into 118 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 4989.0
Subtracting 108 from 118 leaves us with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 12

On to step 6:
When dividing 106 by 12, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 49898.0
Subtracting 96 from 106 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 49898.8
Subtract 96 from 100 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.

Going ahead to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 49898.83
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.

Step 9:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 49898.833
The remainder is 4 after subtracting 36 from 40.
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 49898.833, with a leftover of 0.0004.
