168259 divided by 40 
Our goal is to divide 168259 by 40.

Step 1:
40 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 40

Let's proceed to step 2:
40 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 40

Advancing to step 3:
40 goes into 168 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 160 from 168 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 40

Let's proceed to step 4:
82 divided by 40 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 42.0
Subtracting 80 from 82 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 40

Let's proceed to step 5:
40 can be fit into 25 0 times, resulting in a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 40

Let's proceed to step 6:
40 goes into 259 6 times with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 4206.0
If we take 240 away from 259, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
The number 40 fits into 190 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 4206.4
Deduct 160 from 190 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
40 goes into 300 7 times with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 4206.47
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4206.475
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.

Advancing to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4206.475
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.

Advancing to step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4206.475
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.

Our division results in 4206.475 with a remaining 0.0.
