Let's divide 741343 by 40
We want to figure out the number of times 741343 can be divided by 40.

On to step 1:
When dividing 7 by 40, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 40

Step 2:
When dividing 74 by 40, we get 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
If we take 40 away from 74, we end up with 34.
Append the next digit (1) from the dividend to 34 and continue with: 341 / 40

Going ahead to step 3:
341 divided by 40 is 8 with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 21 after subtracting 320 from 341.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 40

Moving on to step 4:
40 can be fit into 213 5 times, resulting in a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
The remainder is 13 after subtracting 200 from 213.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 40

Step 5:
If we divide 134 by 40, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 1853.0
Deduct 120 from 134 and we're left with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 40

Advancing to step 6:
The number 40 fits into 143 3 times, leaving a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 18533.0
If we subtract 120 from 143, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
The number 40 fits into 230 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 18533.5
Deduct 200 from 230 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:
300 divided by 40 is 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 18533.57
Deduct 280 from 300 and we're left 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 9:
200 divided by 40 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 18533.575
Subtract 200 from 200 to 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 10:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18533.575
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.

Going ahead to step 11:
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: 18533.575
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 quotient of the division is 18533.575, and the remainder is 0.0.
