Let's divide 280343 by 51
The aim is to understand the frequency of 51 in 280343.

Let's proceed to step 1:
The number 51 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 51

Step 2:
When dividing 28 by 51, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 51

Step 3:
The number 51 fits into 280 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 255 away from 280, we end up with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 51

Let's proceed to step 4:
253 divided by 51 is 4 with a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we subtract 204 from 253, we get 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 51

Step 5:
When dividing 494 by 51, we get 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 549.0
Deduct 459 from 494 and we're left with 35.
Grab the next digit (3) from the dividend, add it to 35, then carry on: 353 / 51

Going ahead to step 6:
The number 51 fits into 353 6 times, leaving a remainder of 47.
The number 6 becomes the next digit in our result. 
Result so far: 5496.0
The remainder is 47 after subtracting 306 from 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
The number 51 fits into 470 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 5496.9
Subtract 459 from 470 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
If we divide 110 by 51, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 5496.92
Deduct 102 from 110 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 51, we get 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 5496.921
Subtract 51 from 80 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
51 goes into 290 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 5496.9215
Subtracting 255 from 290 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
51 goes into 350 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 5496.92156
Subtract 306 from 350 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 5496.921568
Deduct 408 from 440 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
51 can be fit into 320 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 5496.9215686
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
140 divided by 51 is 2 with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 5496.92156862
The remainder is 38 after subtracting 102 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 5496.92156862 and a remainder of 3.8e-08.
