386511 ÷ 45 
We want to figure out the number of times 386511 can be divided by 45.

Advancing to step 1:
3 divided by 45 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 45

Step 2:
38 divided by 45 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 45

Going ahead to step 3:
If we divide 386 by 45, we get 8 and a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 26 after subtracting 360 from 386.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 45

Advancing to step 4:
When dividing 265 by 45, we get 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtracting 225 from 265 leaves us with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 45

Step 5:
When dividing 401 by 45, we get 8 with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 858.0
Subtract 360 from 401 to get 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 45

Moving on to step 6:
411 divided by 45 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 8589.0
Deduct 405 from 411 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 45, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 8589.1
Deduct 45 from 60 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
150 divided by 45 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 8589.13
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
45 goes into 150 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 8589.133
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 8589.133, with a leftover of 0.0015.
