648242 ÷ 40 
We're looking to find how many times 40 goes into 648242.

On to step 1:
If we divide 6 by 40, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 40

Going ahead to step 2:
40 goes into 64 1 times with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 40 away from 64, we end up with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 40

Going ahead to step 3:
When dividing 248 by 40, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 240 away from 248, we end up with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 40

Going ahead to step 4:
If we divide 82 by 40, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
If we subtract 80 from 82, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 40

On to step 5:
When dividing 24 by 40, we get 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 1620.0
Deduct 0 from 24 and we're left with 24.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 40

Moving on to step 6:
40 goes into 242 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 16206.0
If we subtract 240 from 242, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 40 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 16206.0
Deduct 0 from 20 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.

Moving on to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 16206.05
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.

Step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16206.05
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.

Advancing to step 10:
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: 16206.05
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 quotient of the division is 16206.05, and the remainder is 0.0.
