45210200 ÷ 301 
The aim is to understand the frequency of 301 in 45210200.

Let's proceed to step 1:
When dividing 4 by 301, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 301

Step 2:
When dividing 45 by 301, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 301

Step 3:
The number 301 fits into 452 1 times, leaving a remainder of 151.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 301 from 452 to get 151.
Append the next digit (1) from the dividend to 151 and continue with: 1511 / 301

On to step 4:
The number 301 fits into 1511 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 1505 from 1511, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 301

Going ahead to step 5:
When dividing 60 by 301, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 150.0
If we subtract 0 from 60, we get 60.
Bring next digit (2) of the dividend behind the 60 and repeat the process: 602 / 301

Let's proceed to step 6:
301 goes into 602 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1502.0
The remainder is 0 after subtracting 602 from 602.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 301

Advancing to step 7:
If we divide 0 by 301, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 15020.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 301

On to step 8:
301 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 150200.0
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.

Moving on to step 9:
The number 301 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 150200.0
If we subtract 0 from 0, we 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.

Advancing to step 10:
301 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 150200.0
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 quotient of the division is 150200.0, and the remainder is 0.0.
