We divide 648976 by 51
The aim is to understand the frequency of 51 in 648976.

Moving on to step 1:
When dividing 6 by 51, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 51

On to step 2:
If we divide 64 by 51, we get 1 and a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 13 after subtracting 51 from 64.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 51

Advancing to step 3:
51 goes into 138 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 102 from 138, we get 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 51

Step 4:
51 goes into 369 7 times with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Deduct 357 from 369 and we're left with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 51

Moving on to step 5:
127 divided by 51 is 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 1272.0
Deduct 102 from 127 and we're left with 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 51

Let's proceed to step 6:
If we divide 256 by 51, we get 5 and a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 12725.0
If we take 255 away from 256, we end up 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.

Let's proceed to step 7:
51 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 12725.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
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: 12725.01
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.

Moving on to step 9:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 12725.019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
The number 51 fits into 310 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 12725.0196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
40 divided by 51 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 12725.0196
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
400 divided by 51 is 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 12725.019607
If we take 357 away from 400, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 13:
51 can be fit into 430 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 12725.0196078
Deduct 408 from 430 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
51 can be fit into 220 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 12725.01960784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 12725.01960784 with a remainder of 1.6e-08.
