We look at the division of 149644 by 40 
We want to divide 149644 by 40.

Advancing to step 1:
40 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 40

Step 2:
When dividing 14 by 40, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 40

On to step 3:
40 can be fit into 149 3 times, resulting in a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 29 after subtracting 120 from 149.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 40

Let's proceed to step 4:
40 goes into 296 7 times with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Subtracting 280 from 296 leaves us with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 40

On to step 5:
The number 40 fits into 164 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 374.0
The remainder is 4 after subtracting 160 from 164.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 40

Moving on to step 6:
40 can be fit into 44 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 3741.0
Subtract 40 from 44 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 40, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 3741.1
Subtracting 40 from 40 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.

On to step 8:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3741.1
If we subtract 0 from 0, we 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.

Moving on to step 9:
40 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3741.1
Subtracting 0 from 0 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.

The final result is 3741.1 with a remainder of 0.0.
