We look at the division of 21451841 by 755 
The aim is to understand the frequency of 755 in 21451841.

Moving on to step 1:
755 can be fit into 2 0 times, resulting in 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.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 755

On to step 2:
21 divided by 755 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 755

On to step 3:
755 goes into 214 0 times with a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 214 and we're left with 214.
Fetch the next digit (5) from the dividend, attach it to 214 and continue: 2145 / 755

Step 4:
755 goes into 2145 2 times with a remainder of 635.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1510 from 2145 to get 635.
Take the next digit (1) from the dividend and append it to 635, then repeat: 6351 / 755

Step 5:
755 can be fit into 6351 8 times, resulting in a remainder of 311.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 6040 away from 6351, we end up with 311.
Include the next digit (8) from the dividend after 311, then repeat: 3118 / 755

Advancing to step 6:
The number 755 fits into 3118 4 times, leaving a remainder of 98.
Write down 4 as next digit of the result. 
Result so far: 284.0
Subtracting 3020 from 3118 leaves us with 98.
Take the next digit (4) from the dividend and append it to 98, then repeat: 984 / 755

Advancing to step 7:
755 goes into 984 1 times with a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 2841.0
The remainder is 229 after subtracting 755 from 984.
Bring next digit (1) of the dividend behind the 229 and repeat the process: 2291 / 755

Step 8:
If we divide 2291 by 755, we get 3 and a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 28413.0
The remainder is 26 after subtracting 2265 from 2291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
If we divide 260 by 755, we get 0 and a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 28413.0
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 10:
If we divide 2600 by 755, we get 3 and a remainder of 335.
Use 3 as the next digit of our solution. 
Result so far: 28413.03
Subtracting 2265 from 2600 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 11:
755 can be fit into 3350 4 times, resulting in a remainder of 330.
Write down 4 as next digit of the result. 
Result so far: 28413.034
Subtract 3020 from 3350 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 12:
The number 755 fits into 3300 4 times, leaving a remainder of 280.
The next digit of our result is 4. 
Result so far: 28413.0344
Deduct 3020 from 3300 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

In conclusion, the division gives 28413.0344 with a balance of 0.0028.
