219541 ÷ 51 
The aim is to understand the frequency of 51 in 219541.

Let's proceed to step 1:
When dividing 2 by 51, we get 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 51

On to step 2:
When dividing 21 by 51, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 51

On to step 3:
When dividing 219 by 51, we get 4 with a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 204 from 219, we get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 51

On to step 4:
If we divide 155 by 51, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 153 from 155 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 51

Moving on to step 5:
The number 51 fits into 24 0 times, leaving a remainder of 24.
The next digit of our result is 0. 
Result so far: 430.0
The remainder is 24 after subtracting 0 from 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 51

On to step 6:
241 divided by 51 is 4 with a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 4304.0
Deduct 204 from 241 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
When dividing 370 by 51, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 4304.7
Subtracting 357 from 370 leaves us 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.

Going ahead to step 8:
If we divide 130 by 51, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 4304.72
Deduct 102 from 130 and we're left 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.

Step 9:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 4304.725
The remainder is 25 after subtracting 255 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 10:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 4304.7254
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.

On to step 11:
51 goes into 460 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4304.72549
Deduct 459 from 460 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
51 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4304.72549
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
51 can be fit into 100 1 times, resulting in a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 4304.7254901
If we subtract 51 from 100, we 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.

Advancing to step 14:
490 divided by 51 is 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 4304.72549019
Subtract 459 from 490 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.

In conclusion, the division gives 4304.72549019 with a balance of 3.1e-08.
