We look at the division of 846574 by 3 
We want to figure out the number of times 846574 can be divided by 3.

On to step 1:
3 goes into 8 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

On to step 2:
24 divided by 3 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 24 from 24 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 3

Advancing to step 3:
6 divided by 3 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 282.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

Advancing to step 4:
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: 2821.0
If we subtract 3 from 5, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 3

Step 5:
3 goes into 27 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 28219.0
Subtracting 27 from 27 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 3

Going ahead to step 6:
If we divide 4 by 3, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 282191.0
If we take 3 away from 4, we end up 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.

On to step 7:
10 divided by 3 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 282191.3
Deduct 9 from 10 and we're left 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.

Moving on to step 8:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 282191.33
Deduct 9 from 10 and we're left 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.

The final outcome is 282191.33, with a leftover of 0.001.
