519166 divided by 10 
We want to figure out the number of times 519166 can be divided by 10.

Moving on to step 1:
If we divide 5 by 10, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 10

Going ahead to step 2:
10 goes into 51 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 1 after subtracting 50 from 51.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 10

Moving on to step 3:
10 goes into 19 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 10 from 19, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 10

Advancing to step 4:
10 can be fit into 91 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 519.0
If we subtract 90 from 91, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 10

Moving on to step 5:
10 goes into 16 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 5191.0
If we take 10 away from 16, we end up with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 10

Advancing to step 6:
10 can be fit into 66 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 51916.0
If we take 60 away from 66, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 10, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 51916.6
If we take 60 away from 60, 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.

On to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51916.6
The remainder is 0 after subtracting 0 from 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:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 51916.6
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 final outcome is 51916.6, with a leftover of 0.0.
