90513233 divided by 211 
The aim is to understand the frequency of 211 in 90513233.

Advancing to step 1:
9 divided by 211 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 211

On to step 2:
90 divided by 211 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Grab the next digit (5) from the dividend, add it to 90, then carry on: 905 / 211

Going ahead to step 3:
If we divide 905 by 211, we get 4 and a remainder of 61.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 844 from 905 and we're left with 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 211

Moving on to step 4:
If we divide 611 by 211, we get 2 and a remainder of 189.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtract 422 from 611 to get 189.
Grab the next digit (3) from the dividend, add it to 189, then carry on: 1893 / 211

Moving on to step 5:
211 can be fit into 1893 8 times, resulting in a remainder of 205.
Record the quotient 8 as the next digit in the result. 
Result so far: 428.0
If we subtract 1688 from 1893, we get 205.
Fetch the next digit (2) from the dividend, attach it to 205 and continue: 2052 / 211

Moving on to step 6:
When dividing 2052 by 211, we get 9 with a remainder of 153.
Use 9 as the next digit of our solution. 
Result so far: 4289.0
If we subtract 1899 from 2052, we get 153.
Take the next digit (3) from the dividend and append it to 153, then repeat: 1533 / 211

Let's proceed to step 7:
1533 divided by 211 is 7 with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 42897.0
The remainder is 56 after subtracting 1477 from 1533.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 211

Moving on to step 8:
563 divided by 211 is 2 with a remainder of 141.
The next digit of our result is 2. 
Result so far: 428972.0
The remainder is 141 after subtracting 422 from 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 9:
211 goes into 1410 6 times with a remainder of 144.
The next digit of our result is 6. 
Result so far: 428972.6
If we take 1266 away from 1410, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 10:
211 goes into 1440 6 times with a remainder of 174.
The next digit of our result is 6. 
Result so far: 428972.66
Deduct 1266 from 1440 and we're left with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Our division results in 428972.66 with a remaining 0.174.
