We divide 510001 by 1
We're looking to find how many times 1 goes into 510001.

Moving on to step 1:
When dividing 5 by 1, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 5 from 5 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Advancing to step 2:
1 goes into 1 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 51.0
If we take 1 away from 1, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Advancing to step 3:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 510.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Advancing to step 4:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 5100.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Moving on to step 5:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 51000.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Moving on to step 6:
If we divide 1 by 1, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 510001.0
If we take 1 away from 1, 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.

Advancing to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 510001.0
Subtract 0 from 0 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.

Moving on to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 510001.0
Subtract 0 from 0 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.

Our division results in 510001.0 with a remaining 0.0.
