257236 divided by 40 
We want to divide 257236 by 40.

Step 1:
When dividing 2 by 40, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 40

On to step 2:
40 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 40

On to step 3:
40 can be fit into 257 6 times, resulting in a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 240 from 257 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 40

Let's proceed to step 4:
40 goes into 172 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtract 160 from 172 to get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 40

Going ahead to step 5:
When dividing 123 by 40, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 643.0
Subtract 120 from 123 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 40

Moving on to step 6:
36 divided by 40 is 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 6430.0
Deduct 0 from 36 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
The number 40 fits into 360 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 6430.9
If we subtract 360 from 360, 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.

On to step 8:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6430.9
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.

Going ahead to step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6430.9
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 6430.9 with a remainder of 0.0.
