Let's divide 854445 by 45
We want to divide 854445 by 45.

Step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 45

Let's proceed to step 2:
If we divide 85 by 45, we get 1 and a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 85, we end up with 40.
Append the next digit (4) from the dividend to 40 and continue with: 404 / 45

On to step 3:
If we divide 404 by 45, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtracting 360 from 404 leaves us with 44.
Fetch the next digit (4) from the dividend, attach it to 44 and continue: 444 / 45

Advancing to step 4:
If we divide 444 by 45, we get 9 and a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 189.0
Subtract 405 from 444 to get 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 45

Moving on to step 5:
If we divide 394 by 45, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 1898.0
Deduct 360 from 394 and we're left with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 45

Advancing to step 6:
45 can be fit into 345 7 times, resulting in a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 18987.0
The remainder is 30 after subtracting 315 from 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
When dividing 300 by 45, we get 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 18987.6
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
45 can be fit into 300 6 times, resulting in a remainder of 30.
The next digit of our result is 6. 
Result so far: 18987.66
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 18987.66 and a remainder of 0.03.
