We're dividing 473842 by 40 
We're looking to find how many times 40 goes into 473842.

Step 1:
40 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 40

Going ahead to step 2:
The number 40 fits into 47 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 40 from 47 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 40

Moving on to step 3:
73 divided by 40 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 40 from 73 to get 33.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 40

Step 4:
When dividing 338 by 40, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 118.0
If we take 320 away from 338, we end up with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 40

Advancing to step 5:
The number 40 fits into 184 4 times, leaving a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 1184.0
Subtracting 160 from 184 leaves us with 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 40

Let's proceed to step 6:
When dividing 242 by 40, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 11846.0
If we take 240 away from 242, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 40, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 11846.0
Subtract 0 from 20 to 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.

On to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11846.05
If we subtract 200 from 200, 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.

Advancing to step 9:
40 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11846.05
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.

On to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11846.05
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 quotient of the division is 11846.05, and the remainder is 0.0.
