Let's divide 72904825 by 972
The aim is to understand the frequency of 972 in 72904825.

Advancing to step 1:
7 divided by 972 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 972

Advancing to step 2:
72 divided by 972 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 972

Step 3:
When dividing 729 by 972, we get 0 with a remainder of 729.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 729 leaves us with 729.
Append the next digit (0) from the dividend to 729 and continue with: 7290 / 972

Going ahead to step 4:
If we divide 7290 by 972, we get 7 and a remainder of 486.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 486 after subtracting 6804 from 7290.
Include the next digit (4) from the dividend after 486, then repeat: 4864 / 972

Going ahead to step 5:
The number 972 fits into 4864 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtracting 4860 from 4864 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 972

Let's proceed to step 6:
When dividing 48 by 972, we get 0 with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 750.0
Subtract 0 from 48 to get 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 972

On to step 7:
972 goes into 482 0 times with a remainder of 482.
Put 0 as the next digit of the answer. 
Result so far: 7500.0
Deduct 0 from 482 and we're left with 482.
Include the next digit (5) from the dividend after 482, then repeat: 4825 / 972

Let's proceed to step 8:
4825 divided by 972 is 4 with a remainder of 937.
Put 4 as the next digit of the answer. 
Result so far: 75004.0
Subtracting 3888 from 4825 leaves us with 937.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9370, and continue the process.

Moving on to step 9:
9370 divided by 972 is 9 with a remainder of 622.
Record the quotient 9 as the next digit in the result. 
Result so far: 75004.9
If we subtract 8748 from 9370, we get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

On to step 10:
972 can be fit into 6220 6 times, resulting in a remainder of 388.
Put 6 as the next digit of the answer. 
Result so far: 75004.96
If we take 5832 away from 6220, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
If we divide 3880 by 972, we get 3 and a remainder of 964.
The number 3 becomes the next digit in our result. 
Result so far: 75004.963
If we subtract 2916 from 3880, we get 964.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9640, and continue the process.

On to step 12:
972 goes into 9640 9 times with a remainder of 892.
The next digit of our result is 9. 
Result so far: 75004.9639
If we take 8748 away from 9640, we end up with 892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8920, and continue the process.

Let's proceed to step 13:
The number 972 fits into 8920 9 times, leaving a remainder of 172.
Write down 9 as next digit of the result. 
Result so far: 75004.96399
Deduct 8748 from 8920 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

After the division, we end up with 75004.96399 and a remainder of 0.000172.
