23637822 ÷ 238 
The aim is to understand the frequency of 238 in 23637822.

Step 1:
If we divide 2 by 238, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 238

Moving on to step 2:
When dividing 23 by 238, we get 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (6) from the dividend, attach it to 23 and continue: 236 / 238

Advancing to step 3:
238 can be fit into 236 0 times, resulting in a remainder of 236.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 236 and we're left with 236.
Include the next digit (3) from the dividend after 236, then repeat: 2363 / 238

Moving on to step 4:
238 goes into 2363 9 times with a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 2142 from 2363 leaves us with 221.
Grab the next digit (7) from the dividend, add it to 221, then carry on: 2217 / 238

Going ahead to step 5:
2217 divided by 238 is 9 with a remainder of 75.
The next digit of our result is 9. 
Result so far: 99.0
Subtracting 2142 from 2217 leaves us with 75.
Take the next digit (8) from the dividend and append it to 75, then repeat: 758 / 238

Moving on to step 6:
238 can be fit into 758 3 times, resulting in a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 993.0
Subtracting 714 from 758 leaves us with 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 238

Moving on to step 7:
If we divide 442 by 238, we get 1 and a remainder of 204.
Record the quotient 1 as the next digit in the result. 
Result so far: 9931.0
If we take 238 away from 442, we end up with 204.
Grab the next digit (2) from the dividend, add it to 204, then carry on: 2042 / 238

Advancing to step 8:
238 goes into 2042 8 times with a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 99318.0
Deduct 1904 from 2042 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
The number 238 fits into 1380 5 times, leaving a remainder of 190.
Use 5 as the next digit of our solution. 
Result so far: 99318.5
Deduct 1190 from 1380 and we're left 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.

Let's proceed to step 10:
When dividing 1900 by 238, we get 7 with a remainder of 234.
The number 7 becomes the next digit in our result. 
Result so far: 99318.57
If we subtract 1666 from 1900, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 11:
238 goes into 2340 9 times with a remainder of 198.
The number 9 becomes the next digit in our result. 
Result so far: 99318.579
If we take 2142 away from 2340, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 12:
When dividing 1980 by 238, we get 8 with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 99318.5798
If we subtract 1904 from 1980, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
238 can be fit into 760 3 times, resulting in a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 99318.57983
Subtract 714 from 760 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
238 goes into 460 1 times with a remainder of 222.
The next digit of our result is 1. 
Result so far: 99318.579831
If we subtract 238 from 460, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 15:
2220 divided by 238 is 9 with a remainder of 78.
Use 9 as the next digit of our solution. 
Result so far: 99318.5798319
Subtract 2142 from 2220 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 16:
If we divide 780 by 238, we get 3 and a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 99318.57983193
Subtracting 714 from 780 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 99318.57983193 and a remainder of 6.6e-08.
