66377 ÷ 40 
Our goal is to divide 66377 by 40.

Step 1:
6 divided by 40 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 40

Going ahead to step 2:
66 divided by 40 is 1 with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 40 away from 66, we end up with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 40

On to step 3:
The number 40 fits into 263 6 times, leaving a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 23 after subtracting 240 from 263.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 40

Advancing to step 4:
237 divided by 40 is 5 with a remainder of 37.
The next digit of our result is 5. 
Result so far: 165.0
If we subtract 200 from 237, we get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 40

Step 5:
377 divided by 40 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 1659.0
If we subtract 360 from 377, 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.

Advancing to step 6:
40 goes into 170 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 1659.4
The remainder is 10 after subtracting 160 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 40 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 1659.42
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.

On to step 8:
200 divided by 40 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1659.425
The remainder is 0 after subtracting 200 from 200.
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 9:
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: 1659.425
Subtract 0 from 0 to 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.

Moving on to step 10:
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: 1659.425
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 quotient of the division is 1659.425, and the remainder is 0.0.
