We're dividing 191937 by 30 
The aim is to understand the frequency of 30 in 191937.

On to step 1:
30 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 30

On to step 2:
When dividing 19 by 30, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 30

Moving on to step 3:
30 can be fit into 191 6 times, resulting in a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 180 away from 191, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 30

On to step 4:
If we divide 119 by 30, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we take 90 away from 119, we end up with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 30

Going ahead to step 5:
30 goes into 293 9 times with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 639.0
Subtracting 270 from 293 leaves us with 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 30

Going ahead to step 6:
30 can be fit into 237 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 6397.0
Subtracting 210 from 237 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
30 goes into 270 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 6397.9
Subtract 270 from 270 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.

On to step 8:
0 divided by 30 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6397.9
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.

Step 9:
If we divide 0 by 30, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6397.9
Subtract 0 from 0 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.

The final outcome is 6397.9, with a leftover of 0.0.
