266537 divided by 40 
Our goal is to divide 266537 by 40.

Going ahead to step 1:
If we divide 2 by 40, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 40

On to step 2:
40 goes into 26 0 times with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 40

Step 3:
40 can be fit into 266 6 times, resulting in a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 26 after subtracting 240 from 266.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 40

On to step 4:
40 can be fit into 265 6 times, resulting in a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 66.0
Subtract 240 from 265 to get 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 40

On to step 5:
40 can be fit into 253 6 times, resulting in a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 666.0
The remainder is 13 after subtracting 240 from 253.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 40

Advancing to step 6:
137 divided by 40 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 6663.0
If we subtract 120 from 137, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
If we divide 170 by 40, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 6663.4
Deduct 160 from 170 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.

Step 8:
100 divided by 40 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 6663.42
Subtract 80 from 100 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.

Going ahead to step 9:
When dividing 200 by 40, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 6663.425
Deduct 200 from 200 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.

Going ahead to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6663.425
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.

Let's proceed to step 11:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6663.425
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 outcome is 6663.425, with a leftover of 0.0.
