We're dividing 20723419 by 233 
The aim is to understand the frequency of 233 in 20723419.

Step 1:
If we divide 2 by 233, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 233

Moving on to step 2:
233 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 233

Moving on to step 3:
233 goes into 207 0 times with a remainder of 207.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 207 to get 207.
Take the next digit (2) from the dividend and append it to 207, then repeat: 2072 / 233

Step 4:
If we divide 2072 by 233, we get 8 and a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 1864 away from 2072, we end up with 208.
Append the next digit (3) from the dividend to 208 and continue with: 2083 / 233

Step 5:
When dividing 2083 by 233, we get 8 with a remainder of 219.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 219 after subtracting 1864 from 2083.
Take the next digit (4) from the dividend and append it to 219, then repeat: 2194 / 233

Advancing to step 6:
233 goes into 2194 9 times with a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 889.0
Subtract 2097 from 2194 to get 97.
Include the next digit (1) from the dividend after 97, then repeat: 971 / 233

Let's proceed to step 7:
The number 233 fits into 971 4 times, leaving a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 8894.0
The remainder is 39 after subtracting 932 from 971.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 233

On to step 8:
If we divide 399 by 233, we get 1 and a remainder of 166.
Write down 1 as next digit of the result. 
Result so far: 88941.0
Subtract 233 from 399 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 9:
1660 divided by 233 is 7 with a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 88941.7
Subtracting 1631 from 1660 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
The number 233 fits into 290 1 times, leaving a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 88941.71
Subtracting 233 from 290 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 11:
The number 233 fits into 570 2 times, leaving a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 88941.712
If we take 466 away from 570, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 12:
233 can be fit into 1040 4 times, resulting in a remainder of 108.
Put 4 as the next digit of the answer. 
Result so far: 88941.7124
If we subtract 932 from 1040, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 13:
233 can be fit into 1080 4 times, resulting in a remainder of 148.
The number 4 becomes the next digit in our result. 
Result so far: 88941.71244
If we subtract 932 from 1080, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final outcome is 88941.71244, with a leftover of 0.000148.
