We divide 158225 by 40
We want to figure out the number of times 158225 can be divided by 40.

Going ahead to step 1:
When dividing 1 by 40, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 40

Advancing to step 2:
If we divide 15 by 40, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 40

On to step 3:
The number 40 fits into 158 3 times, leaving a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 120 from 158 and we're left with 38.
Take the next digit (2) from the dividend and append it to 38, then repeat: 382 / 40

Advancing to step 4:
40 goes into 382 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 360 from 382, we get 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 40

Moving on to step 5:
The number 40 fits into 222 5 times, leaving a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 395.0
Deduct 200 from 222 and we're left with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 40

Step 6:
40 goes into 225 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3955.0
The remainder is 25 after subtracting 200 from 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
When dividing 250 by 40, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 3955.6
The remainder is 10 after subtracting 240 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 40, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 3955.62
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.

Moving on to step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3955.625
Subtracting 200 from 200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3955.625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3955.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3955.625 with a remaining 0.0.
