30275525 ÷ 151 
The aim is to understand the frequency of 151 in 30275525.

On to step 1:
3 divided by 151 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 151

Step 2:
When dividing 30 by 151, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 151

Let's proceed to step 3:
If we divide 302 by 151, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 302 from 302 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 151

Going ahead to step 4:
If we divide 7 by 151, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 151

Let's proceed to step 5:
151 goes into 75 0 times with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
Subtract 0 from 75 to get 75.
Grab the next digit (5) from the dividend, add it to 75, then carry on: 755 / 151

Step 6:
151 goes into 755 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2005.0
If we subtract 755 from 755, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 151

Going ahead to step 7:
When dividing 2 by 151, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 20050.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 151

Moving on to step 8:
When dividing 25 by 151, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 200500.0
If we take 0 away from 25, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
151 can be fit into 250 1 times, resulting in a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 200500.1
Subtract 151 from 250 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 10:
When dividing 990 by 151, we get 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 200500.16
Subtracting 906 from 990 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
When dividing 840 by 151, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 200500.165
Subtracting 755 from 840 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 12:
151 goes into 850 5 times with a remainder of 95.
Put 5 as the next digit of the answer. 
Result so far: 200500.1655
Deduct 755 from 850 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The quotient of the division is 200500.1655, and the remainder is 0.00095.
