We look at the division of 16780170 by 10 
Let's see how many times 10 fits into 16780170.

Step 1:
If we divide 1 by 10, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 10

Going ahead to step 2:
The number 10 fits into 16 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 10 from 16, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 10

Step 3:
10 can be fit into 67 6 times, resulting in a remainder of 7.
The next digit of our result is 6. 
Result so far: 16.0
If we take 60 away from 67, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 10

Let's proceed to step 4:
The number 10 fits into 78 7 times, leaving a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 167.0
If we subtract 70 from 78, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 10

Going ahead to step 5:
10 can be fit into 80 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1678.0
Subtract 80 from 80 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 10

Let's proceed to step 6:
1 divided by 10 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 16780.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 10

Going ahead to step 7:
The number 10 fits into 17 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 167801.0
If we subtract 10 from 17, we get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 10

Advancing to step 8:
10 goes into 70 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1678017.0
Deduct 70 from 70 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.

Step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1678017.0
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.

On to step 10:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1678017.0
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.

The final outcome is 1678017.0, with a leftover of 0.0.
