We're dividing 356434 by 40 
Our goal is to divide 356434 by 40.

Advancing to step 1:
3 divided by 40 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 40

Advancing to step 2:
40 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 40

Let's proceed to step 3:
When dividing 356 by 40, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 320 away from 356, we end up with 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 40

Moving on to step 4:
The number 40 fits into 364 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 89.0
The remainder is 4 after subtracting 360 from 364.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 40

Going ahead to step 5:
The number 40 fits into 43 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 891.0
Subtracting 40 from 43 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 40

On to step 6:
The number 40 fits into 34 0 times, leaving a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 8910.0
Subtract 0 from 34 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
When dividing 340 by 40, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 8910.8
If we take 320 away from 340, we end up 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.

Going ahead to step 8:
40 goes into 200 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8910.85
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 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8910.85
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.

On to step 10:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8910.85
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.

The quotient of the division is 8910.85, and the remainder is 0.0.
