86276620 divided by 30 
The aim is to understand the frequency of 30 in 86276620.

On to step 1:
30 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 30

Step 2:
86 divided by 30 is 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 60 from 86 to get 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 30

Going ahead to step 3:
30 can be fit into 262 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 240 from 262 and we're left with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 30

Advancing to step 4:
30 goes into 227 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
If we subtract 210 from 227, we get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 30

Moving on to step 5:
30 can be fit into 176 5 times, resulting in a remainder of 26.
The number 5 becomes the next digit in our result. 
Result so far: 2875.0
Deduct 150 from 176 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 30

Step 6:
If we divide 266 by 30, we get 8 and a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 28758.0
Subtracting 240 from 266 leaves us with 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 30

On to step 7:
30 goes into 262 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 287588.0
If we subtract 240 from 262, we get 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 30

Let's proceed to step 8:
220 divided by 30 is 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 2875887.0
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
The number 30 fits into 100 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 2875887.3
Subtract 90 from 100 to 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 10:
100 divided by 30 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 2875887.33
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 quotient of the division is 2875887.33, and the remainder is 0.01.
