Let's divide 752558 by 45
The aim is to understand the frequency of 45 in 752558.

Let's proceed to step 1:
45 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 45

Step 2:
45 goes into 75 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 75 and we're left with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 45

Moving on to step 3:
If we divide 302 by 45, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 270 from 302 and we're left with 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 45

Going ahead to step 4:
The number 45 fits into 325 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 167.0
Subtracting 315 from 325 leaves us with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 45

Let's proceed to step 5:
If we divide 105 by 45, we get 2 and a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 1672.0
If we take 90 away from 105, we end up with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 45

Let's proceed to step 6:
If we divide 158 by 45, we get 3 and a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 16723.0
Subtracting 135 from 158 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
230 divided by 45 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 16723.5
Subtracting 225 from 230 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
45 can be fit into 50 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 16723.51
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
50 divided by 45 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 16723.511
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 16723.511, and the remainder is 0.0005.
