We divide 300443 by 40
We're looking to find how many times 40 goes into 300443.

On to step 1:
When dividing 3 by 40, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 40

Advancing to step 2:
40 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 40

Step 3:
40 goes into 300 7 times with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 280 from 300 and we're left with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 40

Going ahead to step 4:
When dividing 204 by 40, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 75.0
The remainder is 4 after subtracting 200 from 204.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 40

Moving on to step 5:
If we divide 44 by 40, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 751.0
Deduct 40 from 44 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 40

On to step 6:
40 goes into 43 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 7511.0
Subtract 40 from 43 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
If we divide 30 by 40, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 7511.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
40 goes into 300 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 7511.07
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
200 divided by 40 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7511.075
Deduct 200 from 200 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.

Let's proceed to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7511.075
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:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7511.075
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 result is 7511.075 with a remainder of 0.0.
