We divide 343524 by 40
We're looking to find how many times 40 goes into 343524.

Moving on to step 1:
3 divided by 40 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 40

Advancing to step 2:
34 divided by 40 is 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 40

On to step 3:
343 divided by 40 is 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 320 from 343, we get 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 40

Advancing to step 4:
The number 40 fits into 235 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 200 from 235 to get 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 40

Advancing to step 5:
40 can be fit into 352 8 times, resulting in a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 858.0
Subtracting 320 from 352 leaves us with 32.
Take the next digit (4) from the dividend and append it to 32, then repeat: 324 / 40

Advancing to step 6:
When dividing 324 by 40, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8588.0
If we take 320 away from 324, we end up 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.

Going ahead to step 7:
40 goes into 40 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 8588.1
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.

On to step 8:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8588.1
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.

Advancing to step 9:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8588.1
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.

After the division, we end up with 8588.1 and a remainder of 0.0.
