8153 divided by 40 
We want to figure out the number of times 8153 can be divided by 40.

Moving on to step 1:
If we divide 8 by 40, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 40

Advancing to step 2:
40 can be fit into 81 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 80 from 81 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 40

Step 3:
40 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 15 to get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 40

Step 4:
The number 40 fits into 153 3 times, leaving a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
Subtracting 120 from 153 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 5:
The number 40 fits into 330 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 203.8
Deduct 320 from 330 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 6:
40 can be fit into 100 2 times, resulting in a remainder of 20.
The next digit of our result is 2. 
Result so far: 203.82
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 203.825
If we subtract 200 from 200, 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.

Step 8:
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: 203.825
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.

Moving on to step 9:
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: 203.825
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.

The final result is 203.825 with a remainder of 0.0.
