We look at the division of 157635 by 45 
The aim is to understand the frequency of 45 in 157635.

On to step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 45

Step 2:
45 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 45

Step 3:
The number 45 fits into 157 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 135 from 157, we get 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 45

Let's proceed to step 4:
226 divided by 45 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 225 from 226 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 45

On to step 5:
13 divided by 45 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 350.0
If we take 0 away from 13, we end up with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 45

On to step 6:
45 goes into 135 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 3503.0
Deduct 135 from 135 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
45 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3503.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3503.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 3503.0 with a balance of 0.0.
