955557 ÷ 30 
The aim is to understand the frequency of 30 in 955557.

Advancing to step 1:
9 divided by 30 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 30

Going ahead to step 2:
If we divide 95 by 30, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 5 after subtracting 90 from 95.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 30

Step 3:
30 goes into 55 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 30 from 55 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 30

Step 4:
When dividing 255 by 30, we get 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 318.0
Deduct 240 from 255 and we're left with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 30

Moving on to step 5:
If we divide 155 by 30, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3185.0
Deduct 150 from 155 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 30

Going ahead to step 6:
30 can be fit into 57 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 31851.0
Subtracting 30 from 57 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.

Going ahead to step 7:
30 goes into 270 9 times with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 31851.9
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.

Step 8:
0 divided by 30 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31851.9
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.

On to step 9:
The number 30 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31851.9
Deduct 0 from 0 and we're left 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.

After the division, we end up with 31851.9 and a remainder of 0.0.
