We're dividing 747640 by 40 
Our goal is to divide 747640 by 40.

Step 1:
40 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 40

Let's proceed to step 2:
The number 40 fits into 74 1 times, leaving a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 40 from 74 to get 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 40

Advancing to step 3:
If we divide 347 by 40, we get 8 and a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 320 from 347 and we're left with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 40

Going ahead to step 4:
If we divide 276 by 40, we get 6 and a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
The remainder is 36 after subtracting 240 from 276.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 40

Step 5:
40 can be fit into 364 9 times, resulting in a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 1869.0
If we take 360 away from 364, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 40

Advancing to step 6:
If we divide 40 by 40, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 18691.0
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.

Let's proceed to step 7:
If we divide 0 by 40, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18691.0
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.

Advancing to step 8:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18691.0
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.

The final result is 18691.0 with a remainder of 0.0.
