Let's divide 753307 by 40
Our goal is to divide 753307 by 40.

Moving on to step 1:
When dividing 7 by 40, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 40

Moving on to step 2:
75 divided by 40 is 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 40 away from 75, we end up with 35.
Append the next digit (3) from the dividend to 35 and continue with: 353 / 40

Moving on to step 3:
The number 40 fits into 353 8 times, leaving a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 33 after subtracting 320 from 353.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 40

On to step 4:
40 goes into 333 8 times with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 188.0
Subtracting 320 from 333 leaves us with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 40

On to step 5:
If we divide 130 by 40, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1883.0
Deduct 120 from 130 and we're left with 10.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 40

Moving on to step 6:
107 divided by 40 is 2 with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 18832.0
Subtracting 80 from 107 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
40 can be fit into 270 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 18832.6
The remainder is 30 after subtracting 240 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 40 fits into 300 7 times, leaving a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 18832.67
The remainder is 20 after subtracting 280 from 300.
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:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18832.675
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18832.675
Subtracting 0 from 0 leaves us 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 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18832.675
Subtracting 0 from 0 leaves us 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 18832.675, with a leftover of 0.0.
