Let's divide 525503 by 31
Our goal is to divide 525503 by 31.

Going ahead to step 1:
31 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 31

Going ahead to step 2:
The number 31 fits into 52 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 31 from 52 and we're left with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 31

Let's proceed to step 3:
If we divide 215 by 31, we get 6 and a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 186 away from 215, we end up with 29.
Include the next digit (5) from the dividend after 29, then repeat: 295 / 31

Going ahead to step 4:
295 divided by 31 is 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 169.0
Deduct 279 from 295 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 31

On to step 5:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1695.0
Deduct 155 from 160 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 31

Step 6:
31 goes into 53 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 16951.0
Subtracting 31 from 53 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
When dividing 220 by 31, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 16951.7
If we take 217 away from 220, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
30 divided by 31 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 16951.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
The number 31 fits into 300 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 16951.709
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 16951.7096
Subtract 186 from 210 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
If we divide 240 by 31, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 16951.70967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
31 goes into 230 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 16951.709677
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 16951.709677 with a remainder of 1.3e-06.
