Let's divide 636596 by 45
The aim is to understand the frequency of 45 in 636596.

Let's proceed to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 45

Moving on to step 2:
If we divide 63 by 45, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 45 from 63 to get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 45

Going ahead to step 3:
186 divided by 45 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Deduct 180 from 186 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 45

Going ahead to step 4:
The number 45 fits into 65 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 141.0
If we take 45 away from 65, we end up with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 45

Advancing to step 5:
The number 45 fits into 209 4 times, leaving a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 1414.0
If we take 180 away from 209, we end up with 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 45

Step 6:
The number 45 fits into 296 6 times, leaving a remainder of 26.
The next digit of our result is 6. 
Result so far: 14146.0
Deduct 270 from 296 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 7:
45 can be fit into 260 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 14146.5
Deduct 225 from 260 and we're left 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.

Let's proceed to step 8:
350 divided by 45 is 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 14146.57
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
If we divide 350 by 45, we get 7 and a remainder of 35.
The next digit of our result is 7. 
Result so far: 14146.577
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 14146.577, with a leftover of 0.0035.
