672210 divided by 40 
Let's see how many times 40 fits into 672210.

On to step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 40

Step 2:
If we divide 67 by 40, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 27 after subtracting 40 from 67.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 40

Moving on to step 3:
When dividing 272 by 40, we get 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 240 from 272, we get 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 40

Advancing to step 4:
322 divided by 40 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
Subtract 320 from 322 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 40

Step 5:
21 divided by 40 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 1680.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 40

Advancing to step 6:
40 can be fit into 210 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 16805.0
The remainder is 10 after subtracting 200 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 40, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 16805.2
Deduct 80 from 100 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.

On to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 16805.25
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.

Step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16805.25
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.

Step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16805.25
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.

Our division results in 16805.25 with a remaining 0.0.
