71728351 ÷ 949 
The aim is to understand the frequency of 949 in 71728351.

Moving on to step 1:
949 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 949

Let's proceed to step 2:
The number 949 fits into 71 0 times, leaving a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 949

Advancing to step 3:
717 divided by 949 is 0 with a remainder of 717.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 717 after subtracting 0 from 717.
Bring next digit (2) of the dividend behind the 717 and repeat the process: 7172 / 949

Going ahead to step 4:
If we divide 7172 by 949, we get 7 and a remainder of 529.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 6643 from 7172 to get 529.
Append the next digit (8) from the dividend to 529 and continue with: 5298 / 949

Going ahead to step 5:
5298 divided by 949 is 5 with a remainder of 553.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 4745 from 5298, we get 553.
Grab the next digit (3) from the dividend, add it to 553, then carry on: 5533 / 949

On to step 6:
The number 949 fits into 5533 5 times, leaving a remainder of 788.
Record the quotient 5 as the next digit in the result. 
Result so far: 755.0
If we take 4745 away from 5533, we end up with 788.
Take the next digit (5) from the dividend and append it to 788, then repeat: 7885 / 949

On to step 7:
949 goes into 7885 8 times with a remainder of 293.
The next digit of our result is 8. 
Result so far: 7558.0
The remainder is 293 after subtracting 7592 from 7885.
Append the next digit (1) from the dividend to 293 and continue with: 2931 / 949

Step 8:
If we divide 2931 by 949, we get 3 and a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 75583.0
Subtract 2847 from 2931 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
The number 949 fits into 840 0 times, leaving a remainder of 840.
Write down 0 as next digit of the result. 
Result so far: 75583.0
If we take 0 away from 840, we end up with 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Let's proceed to step 10:
If we divide 8400 by 949, we get 8 and a remainder of 808.
Record the quotient 8 as the next digit in the result. 
Result so far: 75583.08
Subtracting 7592 from 8400 leaves us with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

On to step 11:
949 goes into 8080 8 times with a remainder of 488.
Use 8 as the next digit of our solution. 
Result so far: 75583.088
The remainder is 488 after subtracting 7592 from 8080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final outcome is 75583.088, with a leftover of 0.0488.
