349879 ÷ 10 
The aim is to understand the frequency of 10 in 349879.

On to step 1:
The number 10 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 10

Going ahead to step 2:
The number 10 fits into 34 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 30 from 34 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 10

Going ahead to step 3:
10 goes into 49 4 times with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Deduct 40 from 49 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 10

Let's proceed to step 4:
If we divide 98 by 10, we get 9 and a remainder of 8.
The next digit of our result is 9. 
Result so far: 349.0
Subtracting 90 from 98 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 10

Let's proceed to step 5:
10 can be fit into 87 8 times, resulting in a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 3498.0
Deduct 80 from 87 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 10

On to step 6:
10 can be fit into 79 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 34987.0
Subtract 70 from 79 to get 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:
When dividing 90 by 10, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 34987.9
Subtracting 90 from 90 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.

Let's proceed to step 8:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34987.9
Deduct 0 from 0 and we're left 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.

Step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34987.9
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.

Our division results in 34987.9 with a remaining 0.0.
