We divide 139492 by 9
The aim is to understand the frequency of 9 in 139492.

Let's proceed to step 1:
9 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 9

Going ahead to step 2:
9 can be fit into 13 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 9 from 13 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 9

On to step 3:
If we divide 49 by 9, we get 5 and a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 45 from 49, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 9

Step 4:
44 divided by 9 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we subtract 36 from 44, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 9

Moving on to step 5:
9 can be fit into 89 9 times, resulting in a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 1549.0
If we take 81 away from 89, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 9

Going ahead to step 6:
82 divided by 9 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 15499.0
Subtracting 81 from 82 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 9, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 15499.1
Subtract 9 from 10 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 8:
If we divide 10 by 9, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 15499.11
Subtract 9 from 10 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.

The quotient of the division is 15499.11, and the remainder is 0.001.
