We look at the division of 19359648 by 973 
The aim is to understand the frequency of 973 in 19359648.

Advancing to step 1:
When dividing 1 by 973, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 973

Moving on to step 2:
19 divided by 973 is 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 973

Step 3:
The number 973 fits into 193 0 times, leaving a remainder of 193.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 193 leaves us with 193.
Append the next digit (5) from the dividend to 193 and continue with: 1935 / 973

On to step 4:
If we divide 1935 by 973, we get 1 and a remainder of 962.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 973 from 1935 and we're left with 962.
Append the next digit (9) from the dividend to 962 and continue with: 9629 / 973

Going ahead to step 5:
The number 973 fits into 9629 9 times, leaving a remainder of 872.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 8757 from 9629 leaves us with 872.
Bring next digit (6) of the dividend behind the 872 and repeat the process: 8726 / 973

Advancing to step 6:
973 goes into 8726 8 times with a remainder of 942.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
If we subtract 7784 from 8726, we get 942.
Include the next digit (4) from the dividend after 942, then repeat: 9424 / 973

Going ahead to step 7:
When dividing 9424 by 973, we get 9 with a remainder of 667.
Use 9 as the next digit of our solution. 
Result so far: 1989.0
Subtract 8757 from 9424 to get 667.
Fetch the next digit (8) from the dividend, attach it to 667 and continue: 6678 / 973

Going ahead to step 8:
973 goes into 6678 6 times with a remainder of 840.
Record the quotient 6 as the next digit in the result. 
Result so far: 19896.0
Subtract 5838 from 6678 to get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Step 9:
973 can be fit into 8400 8 times, resulting in a remainder of 616.
The next digit of our result is 8. 
Result so far: 19896.8
Deduct 7784 from 8400 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Step 10:
The number 973 fits into 6160 6 times, leaving a remainder of 322.
The number 6 becomes the next digit in our result. 
Result so far: 19896.86
Deduct 5838 from 6160 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 11:
3220 divided by 973 is 3 with a remainder of 301.
Record the quotient 3 as the next digit in the result. 
Result so far: 19896.863
If we take 2919 away from 3220, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

On to step 12:
3010 divided by 973 is 3 with a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 19896.8633
If we take 2919 away from 3010, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

The final result is 19896.8633 with a remainder of 0.00091.
