We're dividing 63919 by 72 
The aim is to understand the frequency of 72 in 63919.

Step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 72

Moving on to step 2:
63 divided by 72 is 0 with a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 72

Let's proceed to step 3:
72 goes into 639 8 times with a remainder of 63.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 576 from 639, we get 63.
Bring next digit (1) of the dividend behind the 63 and repeat the process: 631 / 72

Moving on to step 4:
72 can be fit into 631 8 times, resulting in a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtract 576 from 631 to get 55.
Fetch the next digit (9) from the dividend, attach it to 55 and continue: 559 / 72

Step 5:
72 goes into 559 7 times with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 887.0
Deduct 504 from 559 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 6:
If we divide 550 by 72, we get 7 and a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 887.7
If we take 504 away from 550, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
If we divide 460 by 72, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 887.76
Deduct 432 from 460 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.

Going ahead to step 8:
The number 72 fits into 280 3 times, leaving a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 887.763
Subtract 216 from 280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
If we divide 640 by 72, we get 8 and a remainder of 64.
The next digit of our result is 8. 
Result so far: 887.7638
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 10:
640 divided by 72 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 887.76388
If we subtract 576 from 640, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

In conclusion, the division gives 887.76388 with a balance of 6.4e-05.
