We look at the division of 686117 by 40 
Let's see how many times 40 fits into 686117.

Moving on to step 1:
When dividing 6 by 40, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 40

Going ahead to step 2:
40 goes into 68 1 times with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 40 from 68 leaves us with 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 40

Advancing to step 3:
40 can be fit into 286 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 280 from 286, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 40

Going ahead to step 4:
If we divide 61 by 40, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 171.0
Subtracting 40 from 61 leaves us with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 40

Going ahead to step 5:
When dividing 211 by 40, we get 5 with a remainder of 11.
The next digit of our result is 5. 
Result so far: 1715.0
The remainder is 11 after subtracting 200 from 211.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 40

Step 6:
If we divide 117 by 40, we get 2 and a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 17152.0
Subtracting 80 from 117 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
When dividing 370 by 40, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 17152.9
Subtracting 360 from 370 leaves us 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.

Let's proceed to step 8:
If we divide 100 by 40, we get 2 and a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 17152.92
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.

Let's proceed to step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 17152.925
If we take 200 away from 200, 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.

On to step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17152.925
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 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17152.925
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.

The quotient of the division is 17152.925, and the remainder is 0.0.
