443923 ÷ 51 
The aim is to understand the frequency of 51 in 443923.

Advancing to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 51

Advancing to step 2:
The number 51 fits into 44 0 times, leaving a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 51

Let's proceed to step 3:
443 divided by 51 is 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 408 from 443 leaves us with 35.
Take the next digit (9) from the dividend and append it to 35, then repeat: 359 / 51

On to step 4:
The number 51 fits into 359 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 357 away from 359, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 51

Let's proceed to step 5:
The number 51 fits into 22 0 times, leaving a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 870.0
Deduct 0 from 22 and we're left with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 51

Going ahead to step 6:
51 can be fit into 223 4 times, resulting in a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 8704.0
Subtracting 204 from 223 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
190 divided by 51 is 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 8704.3
Subtract 153 from 190 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
The number 51 fits into 370 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 8704.37
If we take 357 away from 370, 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.

On to step 9:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 8704.372
If we take 102 away from 130, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
51 goes into 280 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 8704.3725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 8704.37254
If we subtract 204 from 250, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
51 goes into 460 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8704.372549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
51 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 8704.372549
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
100 divided by 51 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 8704.37254901
Subtract 51 from 100 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final outcome is 8704.37254901, with a leftover of 4.9e-08.
