We look at the division of 37847 by 3 
We want to divide 37847 by 3.

Let's proceed to step 1:
The number 3 fits into 3 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 3 away from 3, we end up with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 3

On to step 2:
If we divide 7 by 3, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 1 after subtracting 6 from 7.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Going ahead to step 3:
3 goes into 18 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 126.0
The remainder is 0 after subtracting 18 from 18.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Moving on to step 4:
If we divide 4 by 3, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1261.0
Deduct 3 from 4 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Step 5:
3 goes into 17 5 times with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 12615.0
If we subtract 15 from 17, 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.

Moving on to step 6:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 12615.6
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 7:
20 divided by 3 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 12615.66
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.

The quotient of the division is 12615.66, and the remainder is 0.002.
