We're dividing 531159 by 3 
We're looking to find how many times 3 goes into 531159.

Advancing to step 1:
5 divided by 3 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Moving on to step 2:
When dividing 23 by 3, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 21 from 23, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 3

Advancing to step 3:
If we divide 21 by 3, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 177.0
Deduct 21 from 21 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Advancing to step 4:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1770.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Advancing to step 5:
When dividing 15 by 3, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 17705.0
Deduct 15 from 15 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 3

Step 6:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 177053.0
Subtracting 9 from 9 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 7:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 177053.0
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.

Advancing to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 177053.0
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.

Our division results in 177053.0 with a remaining 0.0.
