Let's divide 485743 by 45
We're looking to find how many times 45 goes into 485743.

On to step 1:
4 divided by 45 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 45

Step 2:
When dividing 48 by 45, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 45 away from 48, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 45

Moving on 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
Subtracting 0 from 35 leaves us with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 45

Moving on to step 4:
357 divided by 45 is 7 with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 107.0
The remainder is 42 after subtracting 315 from 357.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 45

On to step 5:
If we divide 424 by 45, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 1079.0
If we subtract 405 from 424, we get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 45

Moving on to step 6:
When dividing 193 by 45, we get 4 with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 10794.0
If we subtract 180 from 193, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
45 goes into 130 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 10794.2
If we subtract 90 from 130, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 10794.28
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 10794.288
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 10794.288, with a leftover of 0.004.
