513398 ÷ 10 
We're looking to find how many times 10 goes into 513398.

On to step 1:
10 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 10

Advancing to step 2:
If we divide 51 by 10, we get 5 and 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.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 10

Step 3:
10 can be fit into 13 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 51.0
The remainder is 3 after subtracting 10 from 13.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 10

Step 4:
33 divided by 10 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 513.0
If we subtract 30 from 33, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 10

Let's proceed to step 5:
39 divided by 10 is 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 5133.0
Subtract 30 from 39 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 10

Let's proceed to step 6:
10 can be fit into 98 9 times, resulting in a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 51339.0
Subtract 90 from 98 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
10 goes into 80 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 51339.8
Subtracting 80 from 80 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.

Advancing to step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51339.8
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.

Going ahead to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 51339.8
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 51339.8, with a leftover of 0.0.
