975653 divided by 45 
The aim is to understand the frequency of 45 in 975653.

Advancing to step 1:
The number 45 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 45

Advancing to step 2:
97 divided by 45 is 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 90 from 97 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 45

Going ahead to step 3:
45 can be fit into 75 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 45 away from 75, we end up with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 45

Step 4:
45 goes into 306 6 times with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 216.0
Subtract 270 from 306 to get 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 45

Let's proceed to step 5:
The number 45 fits into 365 8 times, leaving a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 2168.0
If we subtract 360 from 365, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 45

Moving on to step 6:
When dividing 53 by 45, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 21681.0
Deduct 45 from 53 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
45 can be fit into 80 1 times, resulting in a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 21681.1
Subtracting 45 from 80 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
If we divide 350 by 45, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 21681.17
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 21681.177
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 21681.177 and a remainder of 0.0035.
