We divide 485588 by 45
We want to figure out the number of times 485588 can be divided by 45.

On to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 45

On to step 2:
The number 45 fits into 48 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 45 away from 48, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 45

Advancing to step 3:
45 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 35 to get 35.
Bring next digit (5) of the dividend behind the 35 and repeat the process: 355 / 45

Going ahead to step 4:
If we divide 355 by 45, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 107.0
The remainder is 40 after subtracting 315 from 355.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 45

On to step 5:
If we divide 408 by 45, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 1079.0
Subtract 405 from 408 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 45

Advancing to step 6:
45 can be fit into 38 0 times, resulting in a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 10790.0
Deduct 0 from 38 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
The number 45 fits into 380 8 times, leaving a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 10790.8
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 45, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 10790.84
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 45 fits into 200 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 10790.844
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 10790.844, and the remainder is 0.002.
