21333475 ÷ 236 
The aim is to understand the frequency of 236 in 21333475.

Let's proceed to step 1:
If we divide 2 by 236, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 236

Advancing to step 2:
236 goes into 21 0 times with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 236

On to step 3:
When dividing 213 by 236, we get 0 with a remainder of 213.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Take the next digit (3) from the dividend and append it to 213, then repeat: 2133 / 236

On to step 4:
If we divide 2133 by 236, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 2124 from 2133 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 236

Let's proceed to step 5:
236 can be fit into 93 0 times, resulting in a remainder of 93.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtract 0 from 93 to get 93.
Fetch the next digit (4) from the dividend, attach it to 93 and continue: 934 / 236

On to step 6:
236 can be fit into 934 3 times, resulting in a remainder of 226.
The number 3 becomes the next digit in our result. 
Result so far: 903.0
If we subtract 708 from 934, we get 226.
Fetch the next digit (7) from the dividend, attach it to 226 and continue: 2267 / 236

On to step 7:
The number 236 fits into 2267 9 times, leaving a remainder of 143.
The next digit of our result is 9. 
Result so far: 9039.0
If we take 2124 away from 2267, we end up with 143.
Include the next digit (5) from the dividend after 143, then repeat: 1435 / 236

Step 8:
236 goes into 1435 6 times with a remainder of 19.
The next digit of our result is 6. 
Result so far: 90396.0
Deduct 1416 from 1435 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
236 goes into 190 0 times with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 90396.0
Subtracting 0 from 190 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
When dividing 1900 by 236, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 90396.08
If we take 1888 away from 1900, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
236 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 90396.08
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
1200 divided by 236 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 90396.0805
Deduct 1180 from 1200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
200 divided by 236 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 90396.0805
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 14:
If we divide 2000 by 236, we get 8 and a remainder of 112.
The next digit of our result is 8. 
Result so far: 90396.080508
The remainder is 112 after subtracting 1888 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 15:
If we divide 1120 by 236, we get 4 and a remainder of 176.
The next digit of our result is 4. 
Result so far: 90396.0805084
Subtracting 944 from 1120 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 16:
236 can be fit into 1760 7 times, resulting in a remainder of 108.
Record the quotient 7 as the next digit in the result. 
Result so far: 90396.08050847
Deduct 1652 from 1760 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final result is 90396.08050847 with a remainder of 1.08e-07.
