153646 divided by 40 
Our goal is to divide 153646 by 40.

Going ahead to step 1:
If we divide 1 by 40, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 40

Step 2:
When dividing 15 by 40, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 40

Advancing to step 3:
153 divided by 40 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 120 from 153, we get 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 40

Advancing to step 4:
40 goes into 336 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 38.0
Deduct 320 from 336 and we're left with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 40

Let's proceed to step 5:
164 divided by 40 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 384.0
If we take 160 away from 164, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 40

Going ahead to step 6:
When dividing 46 by 40, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 3841.0
Deduct 40 from 46 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 40, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 3841.1
If we take 40 away from 60, 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.

Advancing to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 3841.15
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.

Advancing to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3841.15
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.

Let's proceed to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3841.15
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.

The quotient of the division is 3841.15, and the remainder is 0.0.
