We look at the division of 426684 by 40 
Our goal is to divide 426684 by 40.

On to step 1:
If we divide 4 by 40, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 40

On to step 2:
42 divided by 40 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 40 from 42 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 40

Let's proceed to step 3:
40 can be fit into 26 0 times, resulting in a remainder of 26.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 26 to get 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 40

Advancing to step 4:
The number 40 fits into 266 6 times, leaving a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
The remainder is 26 after subtracting 240 from 266.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 40

Moving on to step 5:
The number 40 fits into 268 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 1066.0
The remainder is 28 after subtracting 240 from 268.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 40

Let's proceed to step 6:
The number 40 fits into 284 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 10667.0
Subtracting 280 from 284 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 40, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 10667.1
If we subtract 40 from 40, 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.

Moving 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: 10667.1
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.

Going ahead to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10667.1
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.

After the division, we end up with 10667.1 and a remainder of 0.0.
