21741793 ÷ 455 
The aim is to understand the frequency of 455 in 21741793.

Moving on to step 1:
2 divided by 455 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 455

Going ahead to step 2:
When dividing 21 by 455, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 455

Let's proceed to step 3:
217 divided by 455 is 0 with a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Append the next digit (4) from the dividend to 217 and continue with: 2174 / 455

On to step 4:
If we divide 2174 by 455, we get 4 and a remainder of 354.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 354 after subtracting 1820 from 2174.
Fetch the next digit (1) from the dividend, attach it to 354 and continue: 3541 / 455

Step 5:
455 can be fit into 3541 7 times, resulting in a remainder of 356.
The next digit of our result is 7. 
Result so far: 47.0
The remainder is 356 after subtracting 3185 from 3541.
Bring next digit (7) of the dividend behind the 356 and repeat the process: 3567 / 455

Going ahead to step 6:
3567 divided by 455 is 7 with a remainder of 382.
Use 7 as the next digit of our solution. 
Result so far: 477.0
If we take 3185 away from 3567, we end up with 382.
Grab the next digit (9) from the dividend, add it to 382, then carry on: 3829 / 455

Moving on to step 7:
455 can be fit into 3829 8 times, resulting in a remainder of 189.
Record the quotient 8 as the next digit in the result. 
Result so far: 4778.0
Subtract 3640 from 3829 to get 189.
Take the next digit (3) from the dividend and append it to 189, then repeat: 1893 / 455

Moving on to step 8:
When dividing 1893 by 455, we get 4 with a remainder of 73.
The next digit of our result is 4. 
Result so far: 47784.0
Subtract 1820 from 1893 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
455 goes into 730 1 times with a remainder of 275.
The number 1 becomes the next digit in our result. 
Result so far: 47784.1
Subtracting 455 from 730 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 10:
When dividing 2750 by 455, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 47784.16
Deduct 2730 from 2750 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
455 goes into 200 0 times with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 47784.16
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
455 goes into 2000 4 times with a remainder of 180.
The next digit of our result is 4. 
Result so far: 47784.1604
If we subtract 1820 from 2000, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 13:
455 goes into 1800 3 times with a remainder of 435.
Use 3 as the next digit of our solution. 
Result so far: 47784.16043
The remainder is 435 after subtracting 1365 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 14:
The number 455 fits into 4350 9 times, leaving a remainder of 255.
The number 9 becomes the next digit in our result. 
Result so far: 47784.160439
The remainder is 255 after subtracting 4095 from 4350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Advancing to step 15:
When dividing 2550 by 455, we get 5 with a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 47784.1604395
Deduct 2275 from 2550 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Advancing to step 16:
455 can be fit into 2750 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 47784.16043956
Subtracting 2730 from 2750 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 47784.16043956 with a remaining 2e-08.
