We divide 729646 by 51
The aim is to understand the frequency of 51 in 729646.

Advancing to step 1:
The number 51 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 51

Going ahead to step 2:
The number 51 fits into 72 1 times, leaving a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 51 from 72 and we're left with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 51

Advancing to step 3:
51 can be fit into 219 4 times, resulting in a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 204 from 219, we get 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 51

Going ahead to step 4:
When dividing 156 by 51, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 143.0
Deduct 153 from 156 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 51

Going ahead to step 5:
51 can be fit into 34 0 times, resulting in a remainder of 34.
The next digit of our result is 0. 
Result so far: 1430.0
The remainder is 34 after subtracting 0 from 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 51

Advancing to step 6:
If we divide 346 by 51, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 14306.0
Subtract 306 from 346 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
51 goes into 400 7 times with a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 14306.7
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 8:
If we divide 430 by 51, we get 8 and a remainder of 22.
The next digit of our result is 8. 
Result so far: 14306.78
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.

Advancing to step 9:
51 can be fit into 220 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14306.784
Deduct 204 from 220 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 14306.7843
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
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: 14306.78431
Subtracting 51 from 70 leaves us 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.

Advancing to step 12:
The number 51 fits into 190 3 times, leaving a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 14306.784313
Subtract 153 from 190 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 13:
51 goes into 370 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 14306.7843137
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.

Advancing to step 14:
51 goes into 130 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 14306.78431372
Deduct 102 from 130 and we're left 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.

The final result is 14306.78431372 with a remainder of 2.8e-08.
