We're dividing 847489 by 51 
The aim is to understand the frequency of 51 in 847489.

Going ahead to step 1:
51 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 51

Advancing to step 2:
If we divide 84 by 51, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 84, we end up with 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 51

Step 3:
337 divided by 51 is 6 with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 306 from 337 to get 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 51

On to step 4:
If we divide 314 by 51, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 166.0
If we subtract 306 from 314, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 51

On to step 5:
51 goes into 88 1 times with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1661.0
If we subtract 51 from 88, we get 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 51

On to step 6:
379 divided by 51 is 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 16617.0
If we subtract 357 from 379, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
The number 51 fits into 220 4 times, leaving a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 16617.4
Subtract 204 from 220 to 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.

Going ahead to step 8:
160 divided by 51 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 16617.43
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
70 divided by 51 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 16617.431
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
If we divide 190 by 51, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 16617.4313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
If we divide 370 by 51, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 16617.43137
Deduct 357 from 370 and we're left 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.

On to step 12:
51 goes into 130 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 16617.431372
If we take 102 away from 130, we end up 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.

On to step 13:
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: 16617.4313725
Subtracting 255 from 280 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
250 divided by 51 is 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 16617.43137254
Subtract 204 from 250 to 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.

In conclusion, the division gives 16617.43137254 with a balance of 4.6e-08.
