We look at the division of 601648 by 40 
We want to divide 601648 by 40.

Step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
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

Advancing to step 2:
When dividing 60 by 40, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 40 away from 60, we end up with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 40

Let's proceed to step 3:
The number 40 fits into 201 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 200 from 201 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 40

Step 4:
16 divided by 40 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 150.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 40

Step 5:
40 goes into 164 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 1504.0
Deduct 160 from 164 and we're left with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 40

Let's proceed to step 6:
When dividing 48 by 40, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 15041.0
Subtract 40 from 48 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 40, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 15041.2
Deduct 80 from 80 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 8:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15041.2
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.

On to step 9:
40 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15041.2
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.

The quotient of the division is 15041.2, and the remainder is 0.0.
