We're dividing 496643 by 45 
Our goal is to divide 496643 by 45.

Going ahead to step 1:
45 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 45

On to step 2:
45 can be fit into 49 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 45 from 49 to get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 45

Step 3:
If we divide 46 by 45, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 45 from 46, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 45

Step 4:
16 divided by 45 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 110.0
If we take 0 away from 16, we end up with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 45

Going ahead to step 5:
45 goes into 164 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 1103.0
If we subtract 135 from 164, we get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 45

Moving on to step 6:
When dividing 293 by 45, we get 6 with a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 11036.0
Deduct 270 from 293 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
When dividing 230 by 45, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 11036.5
If we subtract 225 from 230, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 11036.51
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
The number 45 fits into 50 1 times, leaving a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 11036.511
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 11036.511, with a leftover of 0.0005.
