We're dividing 485996 by 45 
We want to figure out the number of times 485996 can be divided by 45.

Step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 45

Going ahead to step 2:
48 divided by 45 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 45 from 48 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 45

Going ahead to step 3:
35 divided by 45 is 0 with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 45

On to step 4:
45 goes into 359 7 times with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we take 315 away from 359, we end up with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 45

Advancing to step 5:
449 divided by 45 is 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 1079.0
Deduct 405 from 449 and we're left with 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 45

On to step 6:
45 goes into 446 9 times with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 10799.0
The remainder is 41 after subtracting 405 from 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
When dividing 410 by 45, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 10799.9
If we take 405 away from 410, we end up 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.

Going ahead to step 8:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 10799.91
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.

Step 9:
50 divided by 45 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 10799.911
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.

After the division, we end up with 10799.911 and a remainder of 0.0005.
