Let's divide 64254880 by 721
The aim is to understand the frequency of 721 in 64254880.

Moving on to step 1:
721 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 721

Let's proceed to step 2:
721 goes into 64 0 times with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 721

Step 3:
721 goes into 642 0 times with a remainder of 642.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 642 and we're left with 642.
Bring next digit (5) of the dividend behind the 642 and repeat the process: 6425 / 721

Advancing to step 4:
When dividing 6425 by 721, we get 8 with a remainder of 657.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 5768 from 6425 to get 657.
Take the next digit (4) from the dividend and append it to 657, then repeat: 6574 / 721

Step 5:
6574 divided by 721 is 9 with a remainder of 85.
Write down 9 as next digit of the result. 
Result so far: 89.0
The remainder is 85 after subtracting 6489 from 6574.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 721

Going ahead to step 6:
If we divide 858 by 721, we get 1 and a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 891.0
Subtract 721 from 858 to get 137.
Take the next digit (8) from the dividend and append it to 137, then repeat: 1378 / 721

Advancing to step 7:
1378 divided by 721 is 1 with a remainder of 657.
Put 1 as the next digit of the answer. 
Result so far: 8911.0
Subtract 721 from 1378 to get 657.
Append the next digit (0) from the dividend to 657 and continue with: 6570 / 721

Step 8:
The number 721 fits into 6570 9 times, leaving a remainder of 81.
Write down 9 as next digit of the result. 
Result so far: 89119.0
The remainder is 81 after subtracting 6489 from 6570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
721 goes into 810 1 times with a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 89119.1
Subtracting 721 from 810 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Let's proceed to step 10:
The number 721 fits into 890 1 times, leaving a remainder of 169.
Put 1 as the next digit of the answer. 
Result so far: 89119.11
If we take 721 away from 890, we end up with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

In conclusion, the division gives 89119.11 with a balance of 0.169.
