756842 divided by 51 
The aim is to understand the frequency of 51 in 756842.

Going ahead to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 51

Going ahead to step 2:
The number 51 fits into 75 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 75 to get 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 51

Step 3:
51 can be fit into 246 4 times, resulting in a remainder of 42.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 204 from 246, we get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 51

Going ahead to step 4:
428 divided by 51 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 148.0
If we subtract 408 from 428, we get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 51

Advancing to step 5:
204 divided by 51 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 1484.0
Subtracting 204 from 204 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 51

Advancing to step 6:
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: 14840.0
Deduct 0 from 2 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
51 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 14840.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
51 goes into 200 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 14840.03
The remainder is 47 after subtracting 153 from 200.
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 9:
When dividing 470 by 51, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 14840.039
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
51 can be fit into 110 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 14840.0392
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
If we divide 80 by 51, we get 1 and a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 14840.03921
The remainder is 29 after subtracting 51 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 14840.039215
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.

Going ahead to step 13:
51 can be fit into 350 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 14840.0392156
If we subtract 306 from 350, we 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.

Advancing to step 14:
If we divide 440 by 51, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 14840.03921568
If we subtract 408 from 440, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 14840.03921568 and a remainder of 3.2e-08.
