We divide 485941 by 3
We want to divide 485941 by 3.

Moving on to step 1:
The number 3 fits into 4 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 3 from 4, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

On to step 2:
When dividing 18 by 3, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 18 from 18 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Let's proceed to step 3:
5 divided by 3 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 161.0
If we take 3 away from 5, we end up with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

Moving on to step 4:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1619.0
If we subtract 27 from 29, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

Moving on to step 5:
If we divide 24 by 3, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 16198.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 3

Going ahead to step 6:
3 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 161980.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 161980.3
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.

Let's proceed to step 8:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 161980.33
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 result is 161980.33 with a remainder of 0.001.
