958454 divided by 12 
The aim is to understand the frequency of 12 in 958454.

Moving on to step 1:
12 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 12

Step 2:
The number 12 fits into 95 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 84 from 95 leaves us with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 12

Let's proceed to step 3:
118 divided by 12 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 79.0
If we subtract 108 from 118, we get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 12

Advancing to step 4:
104 divided by 12 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 798.0
If we take 96 away from 104, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 12

Let's proceed to step 5:
85 divided by 12 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 7987.0
Deduct 84 from 85 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

Moving on to step 6:
When dividing 14 by 12, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 79871.0
The remainder is 2 after subtracting 12 from 14.
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 7:
If we divide 20 by 12, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 79871.1
Deduct 12 from 20 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.

Step 8:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 79871.16
Subtract 72 from 80 to get 8.
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 9:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 79871.166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 79871.166 with a balance of 0.0008.
