21411444 divided by 443 
The aim is to understand the frequency of 443 in 21411444.

Going ahead to step 1:
443 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of 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 / 443

Let's proceed to step 2:
When dividing 21 by 443, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 443

Advancing to step 3:
443 goes into 214 0 times with a remainder of 214.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Take the next digit (1) from the dividend and append it to 214, then repeat: 2141 / 443

Advancing to step 4:
2141 divided by 443 is 4 with a remainder of 369.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1772 from 2141 and we're left with 369.
Take the next digit (1) from the dividend and append it to 369, then repeat: 3691 / 443

Let's proceed to step 5:
3691 divided by 443 is 8 with a remainder of 147.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtracting 3544 from 3691 leaves us with 147.
Take the next digit (4) from the dividend and append it to 147, then repeat: 1474 / 443

Let's proceed to step 6:
If we divide 1474 by 443, we get 3 and a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 483.0
Deduct 1329 from 1474 and we're left with 145.
Include the next digit (4) from the dividend after 145, then repeat: 1454 / 443

Moving on to step 7:
443 goes into 1454 3 times with a remainder of 125.
Put 3 as the next digit of the answer. 
Result so far: 4833.0
If we subtract 1329 from 1454, we get 125.
Include the next digit (4) from the dividend after 125, then repeat: 1254 / 443

Advancing to step 8:
When dividing 1254 by 443, we get 2 with a remainder of 368.
The next digit of our result is 2. 
Result so far: 48332.0
If we take 886 away from 1254, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 9:
If we divide 3680 by 443, we get 8 and a remainder of 136.
The next digit of our result is 8. 
Result so far: 48332.8
Subtracting 3544 from 3680 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
443 goes into 1360 3 times with a remainder of 31.
The next digit of our result is 3. 
Result so far: 48332.83
Subtract 1329 from 1360 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 11:
When dividing 310 by 443, we get 0 with a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 48332.83
Deduct 0 from 310 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 12:
443 goes into 3100 6 times with a remainder of 442.
Put 6 as the next digit of the answer. 
Result so far: 48332.8306
Deduct 2658 from 3100 and we're left with 442.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4420, and continue the process.

On to step 13:
443 can be fit into 4420 9 times, resulting in a remainder of 433.
Put 9 as the next digit of the answer. 
Result so far: 48332.83069
If we subtract 3987 from 4420, we get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Step 14:
443 goes into 4330 9 times with a remainder of 343.
The next digit of our result is 9. 
Result so far: 48332.830699
Subtract 3987 from 4330 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

The final outcome is 48332.830699, with a leftover of 3.43e-05.
