680320 divided by 40 
We're looking to find how many times 40 goes into 680320.

Going ahead to step 1:
When dividing 6 by 40, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 40

Advancing to step 2:
If we divide 68 by 40, we get 1 and a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 40 from 68 and we're left with 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 40

Advancing to step 3:
280 divided by 40 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 280 from 280, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 40

Step 4:
3 divided by 40 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 40

Moving on to step 5:
40 goes into 32 0 times with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 1700.0
If we take 0 away from 32, we end up with 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 40

Moving on to step 6:
If we divide 320 by 40, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 17008.0
If we take 320 away from 320, 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.

Moving on to step 7:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17008.0
Subtract 0 from 0 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.

Advancing to step 8:
When dividing 0 by 40, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17008.0
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.

Our division results in 17008.0 with a remaining 0.0.
