37286 ÷ 30 
The aim is to understand the frequency of 30 in 37286.

Moving on to step 1:
3 divided by 30 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 30

On to step 2:
37 divided by 30 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 30 from 37, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 30

On to step 3:
30 can be fit into 72 2 times, resulting in a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 60 from 72 to get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 30

On to step 4:
The number 30 fits into 128 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Deduct 120 from 128 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 30

Moving on to step 5:
The number 30 fits into 86 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 1242.0
Subtracting 60 from 86 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 6:
If we divide 260 by 30, we get 8 and a remainder of 20.
The next digit of our result is 8. 
Result so far: 1242.8
Subtract 240 from 260 to 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.

Going ahead to step 7:
If we divide 200 by 30, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 1242.86
Deduct 180 from 200 and we're left with 20.
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 8:
30 can be fit into 200 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 1242.866
If we subtract 180 from 200, 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.

The final outcome is 1242.866, with a leftover of 0.002.
