887146 divided by 72 
The aim is to understand the frequency of 72 in 887146.

Let's proceed to step 1:
If we divide 8 by 72, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 72

On to step 2:
88 divided by 72 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 72 away from 88, we end up with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 72

Let's proceed to step 3:
72 can be fit into 167 2 times, resulting in a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 144 from 167, we get 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 72

Step 4:
72 goes into 231 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 123.0
Deduct 216 from 231 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 72

On to step 5:
If we divide 154 by 72, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 1232.0
If we subtract 144 from 154, we get 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 72

Advancing to step 6:
72 goes into 106 1 times with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 12321.0
Deduct 72 from 106 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
340 divided by 72 is 4 with a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 12321.4
If we subtract 288 from 340, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
72 can be fit into 520 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 12321.47
Deduct 504 from 520 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.

Step 9:
The number 72 fits into 160 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 12321.472
The remainder is 16 after subtracting 144 from 160.
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:
160 divided by 72 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 12321.4722
If we subtract 144 from 160, we 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.

Our division results in 12321.4722 with a remaining 0.00016.
