369939 divided by 10 
The aim is to understand the frequency of 10 in 369939.

Step 1:
10 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 10

Step 2:
36 divided by 10 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 30 away from 36, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 10

Advancing to step 3:
10 can be fit into 69 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 60 from 69 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 10

Moving on to step 4:
10 can be fit into 99 9 times, resulting in a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 369.0
Deduct 90 from 99 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 10

On to step 5:
10 goes into 93 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 3699.0
If we subtract 90 from 93, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 10

Going ahead to step 6:
When dividing 39 by 10, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 36993.0
If we take 30 away from 39, we end up 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 10 fits into 90 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 36993.9
If we subtract 90 from 90, 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.

On to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36993.9
If we subtract 0 from 0, 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.

On to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36993.9
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.

Our division results in 36993.9 with a remaining 0.0.
