601538 divided by 40 
Our goal is to divide 601538 by 40.

Step 1:
6 divided by 40 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 40

Step 2:
If we divide 60 by 40, we get 1 and a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 40 away from 60, we end up with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 40

Moving on to step 3:
If we divide 201 by 40, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 200 from 201 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 40

Moving on to step 4:
The number 40 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 40

Going ahead to step 5:
If we divide 153 by 40, we get 3 and a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 1503.0
Deduct 120 from 153 and we're left with 33.
Fetch the next digit (8) from the dividend, attach it to 33 and continue: 338 / 40

Moving on to step 6:
338 divided by 40 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 15038.0
If we subtract 320 from 338, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
If we divide 180 by 40, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 15038.4
Subtract 160 from 180 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15038.45
If we take 200 away from 200, we end up 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.

On to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15038.45
If we take 0 away from 0, we end up 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.

On to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15038.45
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 15038.45 with a remainder of 0.0.
