We're dividing 153330 by 31 
Our goal is to divide 153330 by 31.

Going ahead to step 1:
If we divide 1 by 31, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 31

Advancing to step 2:
15 divided by 31 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 31

Let's proceed to step 3:
31 goes into 153 4 times with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 124 away from 153, we end up with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 31

Advancing to step 4:
If we divide 293 by 31, we get 9 and a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 49.0
Deduct 279 from 293 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 31

Let's proceed to step 5:
If we divide 143 by 31, we get 4 and a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 494.0
If we subtract 124 from 143, we get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 31

Let's proceed to step 6:
The number 31 fits into 190 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 4946.0
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 31 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 4946.1
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
When dividing 90 by 31, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 4946.12
If we subtract 62 from 90, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 4946.129
Subtract 279 from 280 to get 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 10:
If we divide 10 by 31, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4946.129
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
31 goes into 100 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 4946.12903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
When dividing 70 by 31, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 4946.129032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
31 goes into 80 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 4946.1290322
If we subtract 62 from 80, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 4946.1290322 with a remainder of 1.8e-07.
