538637 ÷ 3 
Let's see how many times 3 fits into 538637.

Let's proceed to step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

On to step 2:
If we divide 23 by 3, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 21 from 23 leaves us with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Moving on to step 3:
3 goes into 28 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 179.0
Deduct 27 from 28 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 3

Going ahead to step 4:
16 divided by 3 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 1795.0
Deduct 15 from 16 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Going ahead to step 5:
13 divided by 3 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 17954.0
Subtracting 12 from 13 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Going ahead to step 6:
If we divide 17 by 3, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 179545.0
Subtract 15 from 17 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.

Step 7:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 179545.6
If we take 18 away from 20, we end up 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.

On to step 8:
3 goes into 20 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 179545.66
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 179545.66 with a remaining 0.002.
