We're dividing 531573 by 31 
We want to figure out the number of times 531573 can be divided by 31.

Moving on to step 1:
The number 31 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 31

Step 2:
When dividing 53 by 31, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 22 after subtracting 31 from 53.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 31

Advancing to step 3:
31 goes into 221 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 217 from 221, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 31

On to step 4:
45 divided by 31 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 171.0
Deduct 31 from 45 and we're left with 14.
Take the next digit (7) from the dividend and append it to 14, then repeat: 147 / 31

On to step 5:
When dividing 147 by 31, we get 4 with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 1714.0
If we take 124 away from 147, we end up with 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 31

Advancing to step 6:
233 divided by 31 is 7 with a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 17147.0
Subtracting 217 from 233 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
160 divided by 31 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 17147.5
Subtract 155 from 160 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
31 goes into 50 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 17147.51
The remainder is 19 after subtracting 31 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
When dividing 190 by 31, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 17147.516
The remainder is 4 after subtracting 186 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
If we divide 40 by 31, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 17147.5161
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 11:
31 goes into 90 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 17147.51612
Subtract 62 from 90 to 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.

On to step 12:
31 can be fit into 280 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 17147.516129
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 13:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 17147.516129
The remainder is 10 after subtracting 0 from 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 14:
When dividing 100 by 31, we get 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 17147.51612903
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 17147.51612903 with a balance of 7e-09.
