337986 divided by 30 
The aim is to understand the frequency of 30 in 337986.

Step 1:
30 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 30

Moving on to step 2:
33 divided by 30 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 30 away from 33, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 30

Let's proceed to step 3:
If we divide 37 by 30, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 30 from 37, we get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 30

Advancing to step 4:
30 can be fit into 79 2 times, resulting in a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 112.0
Subtract 60 from 79 to get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 30

On to step 5:
When dividing 198 by 30, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 1126.0
If we take 180 away from 198, we end up with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 30

Moving on to step 6:
When dividing 186 by 30, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 11266.0
If we subtract 180 from 186, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
When dividing 60 by 30, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 11266.2
Subtract 60 from 60 to 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.

Step 8:
30 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11266.2
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.

Moving on to step 9:
0 divided by 30 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11266.2
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.

The final outcome is 11266.2, with a leftover of 0.0.
