996141 ÷ 12 
The aim is to understand the frequency of 12 in 996141.

Let's proceed to step 1:
If we divide 9 by 12, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 12

Going ahead to step 2:
When dividing 99 by 12, we get 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 96 from 99, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 12

On to step 3:
The number 12 fits into 36 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtract 36 from 36 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 12

Going ahead to step 4:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 830.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

Let's proceed to step 5:
When dividing 14 by 12, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 8301.0
Subtract 12 from 14 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 12

Going ahead to step 6:
The number 12 fits into 21 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 83011.0
Deduct 12 from 21 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.

Let's proceed to step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 83011.7
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 83011.75
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 12 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 83011.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 83011.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 83011.75, with a leftover of 0.0.
