We look at the division of 213159 by 3 
We want to divide 213159 by 3.

Moving on to step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Let's proceed to step 2:
21 divided by 3 is 7 with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 21 from 21 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 3

Going ahead to step 3:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 71.0
Subtracting 3 from 3 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Step 4:
When dividing 1 by 3, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 710.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 3

On to step 5:
15 divided by 3 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7105.0
Deduct 15 from 15 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 3

Advancing to step 6:
9 divided by 3 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 71053.0
Subtract 9 from 9 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.

Advancing to step 7:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 71053.0
If we take 0 away from 0, 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.

Step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 71053.0
If we take 0 away from 0, 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.

The final outcome is 71053.0, with a leftover of 0.0.
