691656 divided by 40 
Let's see how many times 40 fits into 691656.

Going ahead to step 1:
40 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 40

Moving on to step 2:
40 can be fit into 69 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 40 from 69, we get 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 40

Moving on to step 3:
When dividing 291 by 40, we get 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 280 from 291 and we're left with 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 40

Moving on to step 4:
If we divide 116 by 40, we get 2 and a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Deduct 80 from 116 and we're left with 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 40

On to step 5:
365 divided by 40 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 1729.0
Deduct 360 from 365 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 40

Advancing to step 6:
If we divide 56 by 40, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 17291.0
The remainder is 16 after subtracting 40 from 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
When dividing 160 by 40, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 17291.4
If we subtract 160 from 160, 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.

Let's proceed to step 8:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 17291.4
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.

Moving on to step 9:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17291.4
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.

The final outcome is 17291.4, with a leftover of 0.0.
