We're dividing 976003 by 45 
The aim is to understand the frequency of 45 in 976003.

Going ahead to step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 45

Going ahead to step 2:
45 goes into 97 2 times with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 90 from 97, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 45

Moving on to step 3:
When dividing 76 by 45, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 45 away from 76, we end up with 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 45

On to step 4:
The number 45 fits into 310 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
Subtract 270 from 310 to get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 45

Moving on to step 5:
400 divided by 45 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 2168.0
Subtracting 360 from 400 leaves us with 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 45

Moving on to step 6:
45 can be fit into 403 8 times, resulting in a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 21688.0
Subtracting 360 from 403 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
45 goes into 430 9 times with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 21688.9
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
45 goes into 250 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 21688.95
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 21688.955
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 21688.955, with a leftover of 0.0025.
