We look at the division of 253651 by 31 
We want to figure out the number of times 253651 can be divided by 31.

Let's proceed to step 1:
The number 31 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 31

On to step 2:
When dividing 25 by 31, we get 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 31

Moving on to step 3:
253 divided by 31 is 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 248 away from 253, we end up with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 31

Let's proceed to step 4:
56 divided by 31 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
The remainder is 25 after subtracting 31 from 56.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 31

On to step 5:
31 goes into 255 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 818.0
Subtract 248 from 255 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 31

Moving on to step 6:
31 goes into 71 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 8182.0
If we take 62 away from 71, we end up 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.

Let's proceed to step 7:
If we divide 90 by 31, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 8182.2
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.

Step 8:
When dividing 280 by 31, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 8182.29
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
31 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 8182.29
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
31 goes into 100 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 8182.2903
Subtract 93 from 100 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
70 divided by 31 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 8182.29032
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.

On to step 12:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 8182.290322
The remainder is 18 after subtracting 62 from 80.
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 outcome is 8182.290322, with a leftover of 1.8e-06.
