215345 divided by 45 
We want to figure out the number of times 215345 can be divided by 45.

Going ahead to step 1:
2 divided by 45 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 45

Moving on to step 2:
If we divide 21 by 45, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 45

Advancing to step 3:
215 divided by 45 is 4 with a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 180 from 215 leaves us with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 45

Moving on to step 4:
When dividing 353 by 45, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 47.0
The remainder is 38 after subtracting 315 from 353.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 45

Let's proceed to step 5:
384 divided by 45 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 478.0
The remainder is 24 after subtracting 360 from 384.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 45

On to step 6:
When dividing 245 by 45, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 4785.0
Deduct 225 from 245 and we're left 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 7:
When dividing 200 by 45, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 4785.4
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.

Moving on to step 8:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4785.44
Subtracting 180 from 200 leaves us 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.

The final result is 4785.44 with a remainder of 0.02.
