480341 divided by 45 
The aim is to understand the frequency of 45 in 480341.

Step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 45

Step 2:
When dividing 48 by 45, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 45 away from 48, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 45

Let's proceed to step 3:
The number 45 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (3) from the dividend to 30 and continue with: 303 / 45

Advancing to step 4:
If we divide 303 by 45, we get 6 and a remainder of 33.
The next digit of our result is 6. 
Result so far: 106.0
Subtracting 270 from 303 leaves us with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 45

Let's proceed to step 5:
The number 45 fits into 334 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 1067.0
If we subtract 315 from 334, we get 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 45

Let's proceed to step 6:
45 can be fit into 191 4 times, resulting in a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 10674.0
Subtracting 180 from 191 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
45 can be fit into 110 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 10674.2
The remainder is 20 after subtracting 90 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
45 goes into 200 4 times with a remainder of 20.
The next digit of our result is 4. 
Result so far: 10674.24
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 10674.244
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 10674.244, with a leftover of 0.002.
