We divide 513942 by 1
We want to divide 513942 by 1.

Moving on to step 1:
5 divided by 1 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 5 from 5 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

On to step 2:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtract 1 from 1 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

On to step 3:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 513.0
If we take 3 away from 3, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Moving on to step 4:
1 goes into 9 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 5139.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 5:
4 divided by 1 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 51394.0
If we subtract 4 from 4, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Going ahead to step 6:
If we divide 2 by 1, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 513942.0
Subtract 2 from 2 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.

Going ahead to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 513942.0
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.

On to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 513942.0
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.

Our division results in 513942.0 with a remaining 0.0.
