973302 divided by 45 
The aim is to understand the frequency of 45 in 973302.

Advancing to step 1:
9 divided by 45 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 45

Going ahead to step 2:
45 can be fit into 97 2 times, resulting in a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 90 from 97 to get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 45

Going ahead to step 3:
The number 45 fits into 73 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 45 from 73 to get 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 45

Going ahead to step 4:
45 goes into 283 6 times with a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 216.0
If we take 270 away from 283, we end up with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 45

Let's proceed to step 5:
45 goes into 130 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 2162.0
Subtract 90 from 130 to get 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 45

Going ahead to step 6:
45 can be fit into 402 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 21628.0
If we take 360 away from 402, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
The number 45 fits into 420 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 21628.9
If we subtract 405 from 420, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 21628.93
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
45 goes into 150 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 21628.933
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 21628.933 and a remainder of 0.0015.
