381449 divided by 40 
We're looking to find how many times 40 goes into 381449.

Step 1:
If we divide 3 by 40, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 40

Moving on to step 2:
If we divide 38 by 40, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 40

Advancing to step 3:
If we divide 381 by 40, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 360 from 381, we get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 40

Going ahead to step 4:
214 divided by 40 is 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Deduct 200 from 214 and we're left with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 40

Going ahead to step 5:
144 divided by 40 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 953.0
Deduct 120 from 144 and we're left with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 40

Step 6:
40 can be fit into 249 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 9536.0
Subtract 240 from 249 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 40 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 9536.2
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
40 goes into 100 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 9536.22
If we take 80 away from 100, we end up 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.

Our division results in 9536.22 with a remaining 0.02.
