We look at the division of 31307 by 84 
We want to divide 31307 by 84.

Advancing to step 1:
If we divide 3 by 84, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 84

Going ahead to step 2:
84 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 84

Moving on to step 3:
84 goes into 313 3 times with a remainder of 61.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 252 away from 313, we end up with 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 84

Step 4:
When dividing 610 by 84, we get 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 22 after subtracting 588 from 610.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 84

Let's proceed to step 5:
If we divide 227 by 84, we get 2 and a remainder of 59.
Use 2 as the next digit of our solution. 
Result so far: 372.0
Deduct 168 from 227 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 6:
84 can be fit into 590 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 372.7
Subtracting 588 from 590 leaves us 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.

Let's proceed to step 7:
When dividing 20 by 84, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 372.7
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
If we divide 200 by 84, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 372.702
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 84, we get 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 372.7023
Deduct 252 from 320 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 10:
If we divide 680 by 84, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 372.70238
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
84 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 372.70238
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 372.7023809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
84 can be fit into 440 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 372.70238095
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 372.70238095, and the remainder is 2e-08.
