We divide 585783 by 45
The aim is to understand the frequency of 45 in 585783.

On to step 1:
The number 45 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 45

Advancing to step 2:
45 can be fit into 58 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 58 leaves us with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 45

Let's proceed to step 3:
45 can be fit into 135 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 0 after subtracting 135 from 135.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 45

Step 4:
45 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 130.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 45

Advancing to step 5:
45 goes into 78 1 times with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1301.0
Subtracting 45 from 78 leaves us with 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 45

Going ahead to step 6:
333 divided by 45 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 13017.0
If we subtract 315 from 333, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 45 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 13017.4
Subtract 180 from 180 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 13017.4
If we subtract 0 from 0, we get 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 9:
45 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13017.4
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.

After the division, we end up with 13017.4 and a remainder of 0.0.
