381225 divided by 45 
Our goal is to divide 381225 by 45.

Moving on to step 1:
If we divide 3 by 45, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 45

Advancing to step 2:
If we divide 38 by 45, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 45

Moving on to step 3:
When dividing 381 by 45, we get 8 with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 360 away from 381, we end up with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 45

Advancing to step 4:
45 can be fit into 212 4 times, resulting in a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 180 from 212, we get 32.
Take the next digit (2) from the dividend and append it to 32, then repeat: 322 / 45

On to step 5:
45 goes into 322 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 847.0
If we take 315 away from 322, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 45

Going ahead to step 6:
75 divided by 45 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 8471.0
The remainder is 30 after subtracting 45 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
If we divide 300 by 45, we get 6 and a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 8471.6
Subtracting 270 from 300 leaves us 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.

Let's proceed 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: 8471.66
Subtract 270 from 300 to 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 8471.66 and a remainder of 0.03.
