Let's divide 618355 by 45
Our goal is to divide 618355 by 45.

On to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 45

On to step 2:
45 goes into 61 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 45 from 61, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 45

Moving on to step 3:
When dividing 168 by 45, we get 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 33 after subtracting 135 from 168.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 45

Step 4:
333 divided by 45 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 137.0
The remainder is 18 after subtracting 315 from 333.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 45

On to step 5:
If we divide 185 by 45, we get 4 and a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 1374.0
Deduct 180 from 185 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 45

Moving on to step 6:
55 divided by 45 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 13741.0
The remainder is 10 after subtracting 45 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
45 goes into 100 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 13741.2
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.

Going ahead to 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: 13741.22
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 13741.22 and a remainder of 0.01.
