We look at the division of 346223 by 39 
The aim is to understand the frequency of 39 in 346223.

Step 1:
39 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 39

Going ahead to step 2:
If we divide 34 by 39, we get 0 and a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 39

Step 3:
346 divided by 39 is 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 312 away from 346, we end up with 34.
Take the next digit (2) from the dividend and append it to 34, then repeat: 342 / 39

Let's proceed to step 4:
39 can be fit into 342 8 times, resulting in a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 88.0
The remainder is 30 after subtracting 312 from 342.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 39

Step 5:
When dividing 302 by 39, we get 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 887.0
Deduct 273 from 302 and we're left with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 39

On to step 6:
The number 39 fits into 293 7 times, leaving a remainder of 20.
The next digit of our result is 7. 
Result so far: 8877.0
The remainder is 20 after subtracting 273 from 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
200 divided by 39 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 8877.5
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 39, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 8877.51
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
39 goes into 110 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 8877.512
Deduct 78 from 110 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
The number 39 fits into 320 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 8877.5128
If we subtract 312 from 320, 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.

Let's proceed to step 11:
If we divide 80 by 39, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 8877.51282
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
39 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8877.51282
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
200 divided by 39 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 8877.5128205
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
The number 39 fits into 50 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 8877.51282051
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 8877.51282051, and the remainder is 1.1e-08.
