We divide 616389 by 45
We're looking to find how many times 45 goes into 616389.

Moving on to step 1:
45 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 45

Step 2:
If we divide 61 by 45, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 45 from 61, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 45

Going ahead to step 3:
The number 45 fits into 166 3 times, leaving a remainder of 31.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 31 after subtracting 135 from 166.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 45

On to step 4:
When dividing 313 by 45, we get 6 with a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
If we subtract 270 from 313, we get 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 45

On to step 5:
The number 45 fits into 438 9 times, leaving a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 1369.0
Deduct 405 from 438 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 45

Step 6:
If we divide 339 by 45, we get 7 and a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 13697.0
If we subtract 315 from 339, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
240 divided by 45 is 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 13697.5
Subtract 225 from 240 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
If we divide 150 by 45, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 13697.53
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.

Moving on to step 9:
When dividing 150 by 45, we get 3 with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 13697.533
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.

The final result is 13697.533 with a remainder of 0.0015.
