618153 divided by 40 
We want to figure out the number of times 618153 can be divided by 40.

On to step 1:
6 divided by 40 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 40

On to step 2:
40 can be fit into 61 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 40 from 61 and we're left with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 40

Moving on to step 3:
If we divide 218 by 40, we get 5 and a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 200 away from 218, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 40

Moving on to step 4:
The number 40 fits into 181 4 times, leaving a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 154.0
The remainder is 21 after subtracting 160 from 181.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 40

On to step 5:
40 goes into 215 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 1545.0
If we subtract 200 from 215, we get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 40

Let's proceed to step 6:
40 can be fit into 153 3 times, resulting in a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 15453.0
If we subtract 120 from 153, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
40 can be fit into 330 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 15453.8
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.

Going ahead to step 8:
40 goes into 100 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 15453.82
Subtracting 80 from 100 leaves us 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.

Step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15453.825
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.

Advancing to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15453.825
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.

On to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15453.825
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.

Our division results in 15453.825 with a remaining 0.0.
