We're dividing 21241827 by 253 
The aim is to understand the frequency of 253 in 21241827.

Step 1:
The number 253 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 253

On to step 2:
When dividing 21 by 253, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 253

Moving on to step 3:
212 divided by 253 is 0 with a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 212, we end up with 212.
Fetch the next digit (4) from the dividend, attach it to 212 and continue: 2124 / 253

Advancing to step 4:
253 goes into 2124 8 times with a remainder of 100.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 2024 from 2124 and we're left with 100.
Grab the next digit (1) from the dividend, add it to 100, then carry on: 1001 / 253

Let's proceed to step 5:
253 goes into 1001 3 times with a remainder of 242.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 759 from 1001 and we're left with 242.
Bring next digit (8) of the dividend behind the 242 and repeat the process: 2428 / 253

Let's proceed to step 6:
When dividing 2428 by 253, we get 9 with a remainder of 151.
Write down 9 as next digit of the result. 
Result so far: 839.0
Subtracting 2277 from 2428 leaves us with 151.
Bring next digit (2) of the dividend behind the 151 and repeat the process: 1512 / 253

On to step 7:
The number 253 fits into 1512 5 times, leaving a remainder of 247.
Record the quotient 5 as the next digit in the result. 
Result so far: 8395.0
If we take 1265 away from 1512, we end up with 247.
Fetch the next digit (7) from the dividend, attach it to 247 and continue: 2477 / 253

Step 8:
253 can be fit into 2477 9 times, resulting in a remainder of 200.
Record the quotient 9 as the next digit in the result. 
Result so far: 83959.0
If we take 2277 away from 2477, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 9:
When dividing 2000 by 253, we get 7 with a remainder of 229.
Put 7 as the next digit of the answer. 
Result so far: 83959.7
If we subtract 1771 from 2000, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Moving on to step 10:
The number 253 fits into 2290 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 83959.79
If we take 2277 away from 2290, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
130 divided by 253 is 0 with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 83959.79
If we subtract 0 from 130, we get 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 12:
When dividing 1300 by 253, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 83959.7905
Subtract 1265 from 1300 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
If we divide 350 by 253, we get 1 and a remainder of 97.
The number 1 becomes the next digit in our result. 
Result so far: 83959.79051
Subtract 253 from 350 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 14:
970 divided by 253 is 3 with a remainder of 211.
Write down 3 as next digit of the result. 
Result so far: 83959.790513
If we subtract 759 from 970, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 15:
When dividing 2110 by 253, we get 8 with a remainder of 86.
The number 8 becomes the next digit in our result. 
Result so far: 83959.7905138
Deduct 2024 from 2110 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 16:
253 can be fit into 860 3 times, resulting in a remainder of 101.
The number 3 becomes the next digit in our result. 
Result so far: 83959.79051383
Subtract 759 from 860 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

In conclusion, the division gives 83959.79051383 with a balance of 1.01e-07.
