We're dividing 91894 by 30 
The aim is to understand the frequency of 30 in 91894.

Moving on to step 1:
9 divided by 30 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 30

Going ahead to step 2:
If we divide 91 by 30, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 90 from 91 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 30

Advancing to step 3:
When dividing 18 by 30, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 30

On to step 4:
The number 30 fits into 189 6 times, leaving a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 306.0
Subtract 180 from 189 to get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 30

Advancing to step 5:
94 divided by 30 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3063.0
If we subtract 90 from 94, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 6:
30 goes into 40 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 3063.1
If we subtract 30 from 40, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3063.13
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3063.133
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 3063.133, with a leftover of 0.001.
