286429 ÷ 40 
We want to figure out the number of times 286429 can be divided by 40.

Moving on to step 1:
40 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 40

Advancing to step 2:
40 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 40

Moving on to step 3:
40 goes into 286 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 280 from 286, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 40

Step 4:
When dividing 64 by 40, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
The remainder is 24 after subtracting 40 from 64.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 40

Moving on to step 5:
When dividing 242 by 40, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 716.0
If we take 240 away from 242, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 40

On to step 6:
If we divide 29 by 40, we get 0 and a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 7160.0
If we take 0 away from 29, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
40 goes into 290 7 times with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 7160.7
Deduct 280 from 290 and we're left 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.

Going ahead to step 8:
40 goes into 100 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 7160.72
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 40, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7160.725
Subtract 200 from 200 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.

Going ahead to step 10:
40 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7160.725
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.

Let's proceed to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7160.725
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.

In conclusion, the division gives 7160.725 with a balance of 0.0.
