We're dividing 859981 by 3 
We want to figure out the number of times 859981 can be divided by 3.

Step 1:
3 goes into 8 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Moving on to step 2:
If we divide 25 by 3, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 24 from 25 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Advancing to step 3:
When dividing 19 by 3, we get 6 with a remainder of 1.
The next digit of our result is 6. 
Result so far: 286.0
Subtracting 18 from 19 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 3

On to step 4:
19 divided by 3 is 6 with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 2866.0
Deduct 18 from 19 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

Let's proceed to step 5:
When dividing 18 by 3, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 28666.0
Subtracting 18 from 18 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

On to step 6:
The number 3 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 286660.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 286660.3
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 286660.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 286660.33, and the remainder is 0.001.
