Let's divide 215434 by 45
We want to figure out the number of times 215434 can be divided by 45.

Let's proceed to step 1:
45 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 45

Moving on to step 2:
When dividing 21 by 45, we get 0 with 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.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 45

Moving on to step 3:
45 goes into 215 4 times with a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 180 from 215 and we're left with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 45

On to step 4:
The number 45 fits into 354 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 47.0
Subtract 315 from 354 to get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 45

On to step 5:
If we divide 393 by 45, we get 8 and a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 478.0
If we subtract 360 from 393, we get 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 45

Going ahead to step 6:
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: 4787.0
The remainder is 19 after subtracting 315 from 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
The number 45 fits into 190 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4787.4
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 45, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 4787.42
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
The number 45 fits into 100 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 4787.422
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 4787.422 with a remaining 0.001.
