170640 ÷ 6 
We want to figure out the number of times 170640 can be divided by 6.

Advancing to step 1:
6 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 6

Going ahead to step 2:
When dividing 17 by 6, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 12 from 17 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 6

Step 3:
The number 6 fits into 50 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 48 from 50, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 6

Step 4:
When dividing 26 by 6, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 284.0
The remainder is 2 after subtracting 24 from 26.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 6

On to step 5:
6 goes into 24 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 2844.0
If we take 24 away from 24, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 6

On to step 6:
When dividing 0 by 6, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28440.0
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.

Step 7:
0 divided by 6 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28440.0
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.

Moving on to step 8:
When dividing 0 by 6, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28440.0
If we subtract 0 from 0, 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.

The final result is 28440.0 with a remainder of 0.0.
