We look at the division of 23833951 by 245 
The aim is to understand the frequency of 245 in 23833951.

Step 1:
If we divide 2 by 245, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 245

Going ahead to step 2:
When dividing 23 by 245, we get 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 245

Step 3:
The number 245 fits into 238 0 times, leaving a remainder of 238.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 238, we get 238.
Fetch the next digit (3) from the dividend, attach it to 238 and continue: 2383 / 245

Let's proceed to step 4:
The number 245 fits into 2383 9 times, leaving a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 2205 from 2383, we get 178.
Include the next digit (3) from the dividend after 178, then repeat: 1783 / 245

Moving on to step 5:
245 can be fit into 1783 7 times, resulting in a remainder of 68.
The next digit of our result is 7. 
Result so far: 97.0
The remainder is 68 after subtracting 1715 from 1783.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 245

Advancing to step 6:
689 divided by 245 is 2 with a remainder of 199.
Put 2 as the next digit of the answer. 
Result so far: 972.0
Subtract 490 from 689 to get 199.
Fetch the next digit (5) from the dividend, attach it to 199 and continue: 1995 / 245

Let's proceed to step 7:
245 can be fit into 1995 8 times, resulting in a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 9728.0
If we take 1960 away from 1995, we end up with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 245

Moving on to step 8:
245 goes into 351 1 times with a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 97281.0
The remainder is 106 after subtracting 245 from 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
245 goes into 1060 4 times with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 97281.4
The remainder is 80 after subtracting 980 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
800 divided by 245 is 3 with a remainder of 65.
The next digit of our result is 3. 
Result so far: 97281.43
Subtracting 735 from 800 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
650 divided by 245 is 2 with a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 97281.432
If we subtract 490 from 650, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
When dividing 1600 by 245, we get 6 with a remainder of 130.
Use 6 as the next digit of our solution. 
Result so far: 97281.4326
If we take 1470 away from 1600, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 13:
1300 divided by 245 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 97281.43265
Deduct 1225 from 1300 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
245 goes into 750 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 97281.432653
If we take 735 away from 750, 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.

Moving on to step 15:
If we divide 150 by 245, we get 0 and a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 97281.432653
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 16:
245 goes into 1500 6 times with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 97281.43265306
The remainder is 30 after subtracting 1470 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 97281.43265306 with a remainder of 3e-08.
