279285 divided by 51 
The aim is to understand the frequency of 51 in 279285.

Advancing to step 1:
51 goes into 2 0 times with 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.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 51

On to step 2:
51 can be fit into 27 0 times, resulting in a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 51

Let's proceed to step 3:
The number 51 fits into 279 5 times, leaving a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 255 from 279 to get 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 51

Step 4:
If we divide 242 by 51, we get 4 and a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Subtract 204 from 242 to get 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 51

Moving on to step 5:
If we divide 388 by 51, we get 7 and a remainder of 31.
The next digit of our result is 7. 
Result so far: 547.0
The remainder is 31 after subtracting 357 from 388.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 51

On to step 6:
The number 51 fits into 315 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 5476.0
Deduct 306 from 315 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 51 fits into 90 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 5476.1
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
If we divide 390 by 51, we get 7 and a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 5476.17
The remainder is 33 after subtracting 357 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 9:
51 can be fit into 330 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 5476.176
If we take 306 away from 330, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 51, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 5476.1764
If we take 204 away from 240, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
When dividing 360 by 51, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 5476.17647
Subtracting 357 from 360 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
30 divided by 51 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5476.17647
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
51 goes into 300 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 5476.1764705
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 14:
450 divided by 51 is 8 with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 5476.17647058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 5476.17647058 and a remainder of 4.2e-08.
