601859 ÷ 3 
We're looking to find how many times 3 goes into 601859.

On to step 1:
If we divide 6 by 3, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 6 away from 6, we end up with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Let's proceed to step 2:
The number 3 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 0 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

Let's proceed to step 3:
When dividing 1 by 3, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 200.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Step 4:
The number 3 fits into 18 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 2006.0
The remainder is 0 after subtracting 18 from 18.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Let's proceed to step 5:
When dividing 5 by 3, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 20061.0
Deduct 3 from 5 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Advancing to step 6:
If we divide 29 by 3, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 200619.0
Deduct 27 from 29 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
20 divided by 3 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 200619.6
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 200619.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 200619.66 with a remaining 0.002.
