We divide 406868 by 40
We want to figure out the number of times 406868 can be divided by 40.

Moving on to step 1:
The number 40 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 40

Going ahead to step 2:
If we divide 40 by 40, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 40 away from 40, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 40

Advancing to step 3:
When dividing 6 by 40, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 40

Moving on to step 4:
The number 40 fits into 68 1 times, leaving a remainder of 28.
The next digit of our result is 1. 
Result so far: 101.0
The remainder is 28 after subtracting 40 from 68.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 40

Advancing to step 5:
The number 40 fits into 286 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 1017.0
The remainder is 6 after subtracting 280 from 286.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 40

Moving on to step 6:
40 goes into 68 1 times with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 10171.0
Deduct 40 from 68 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
The number 40 fits into 280 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 10171.7
If we take 280 away from 280, 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.

Going ahead to step 8:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10171.7
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.

Going ahead 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: 10171.7
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.

The final outcome is 10171.7, with a leftover of 0.0.
