We're dividing 334213 by 9 
The aim is to understand the frequency of 9 in 334213.

On to step 1:
9 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 9

Advancing to step 2:
9 goes into 33 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 6 after subtracting 27 from 33.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 9

Advancing to step 3:
When dividing 64 by 9, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 63 from 64, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 9

Advancing to step 4:
If we divide 12 by 9, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 371.0
If we subtract 9 from 12, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 9

Step 5:
9 can be fit into 31 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3713.0
The remainder is 4 after subtracting 27 from 31.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 9

Advancing to step 6:
If we divide 43 by 9, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 37134.0
The remainder is 7 after subtracting 36 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 9, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 37134.7
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
The number 9 fits into 70 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 37134.77
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 37134.77, and the remainder is 0.007.
