Let's divide 21514 by 45
The aim is to understand the frequency of 45 in 21514.

Advancing to step 1:
45 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 45

Step 2:
The number 45 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 45

Advancing to step 3:
45 goes into 215 4 times with a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 180 away from 215, we end up with 35.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 45

Moving on to step 4:
The number 45 fits into 351 7 times, leaving a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we subtract 315 from 351, we get 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 45

On to step 5:
45 goes into 364 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 478.0
If we take 360 away from 364, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 6:
If we divide 40 by 45, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 478.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
400 divided by 45 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 478.08
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 478.088
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 478.088 and a remainder of 0.004.
