We look at the division of 21850608 by 705 
The aim is to understand the frequency of 705 in 21850608.

Let's proceed to step 1:
The number 705 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 705

Going ahead to step 2:
705 goes into 21 0 times with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 705

Moving on to step 3:
705 can be fit into 218 0 times, resulting in a remainder of 218.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Fetch the next digit (5) from the dividend, attach it to 218 and continue: 2185 / 705

Going ahead to step 4:
2185 divided by 705 is 3 with a remainder of 70.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2115 from 2185, we get 70.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 705

Let's proceed to step 5:
705 can be fit into 700 0 times, resulting in a remainder of 700.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we take 0 away from 700, we end up with 700.
Bring next digit (6) of the dividend behind the 700 and repeat the process: 7006 / 705

On to step 6:
When dividing 7006 by 705, we get 9 with a remainder of 661.
Use 9 as the next digit of our solution. 
Result so far: 309.0
Subtract 6345 from 7006 to get 661.
Take the next digit (0) from the dividend and append it to 661, then repeat: 6610 / 705

Let's proceed to step 7:
When dividing 6610 by 705, we get 9 with a remainder of 265.
The number 9 becomes the next digit in our result. 
Result so far: 3099.0
If we subtract 6345 from 6610, we get 265.
Bring next digit (8) of the dividend behind the 265 and repeat the process: 2658 / 705

Moving on to step 8:
When dividing 2658 by 705, we get 3 with a remainder of 543.
Write down 3 as next digit of the result. 
Result so far: 30993.0
Subtracting 2115 from 2658 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

Advancing to step 9:
The number 705 fits into 5430 7 times, leaving a remainder of 495.
Record the quotient 7 as the next digit in the result. 
Result so far: 30993.7
If we take 4935 away from 5430, we end up with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Step 10:
705 can be fit into 4950 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 30993.77
If we take 4935 away from 4950, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 30993.77 with a balance of 0.015.
