Let's divide 172648 by 31
We want to divide 172648 by 31.

Advancing to step 1:
The number 31 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 31

Going ahead to step 2:
31 can be fit into 17 0 times, resulting in a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 31

Let's proceed to step 3:
31 goes into 172 5 times with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 155 from 172 leaves us with 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 31

Step 4:
31 can be fit into 176 5 times, resulting in a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtracting 155 from 176 leaves us with 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 31

On to step 5:
31 goes into 214 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 556.0
Subtracting 186 from 214 leaves us with 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 31

Step 6:
The number 31 fits into 288 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 5569.0
The remainder is 9 after subtracting 279 from 288.
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 7:
31 can be fit into 90 2 times, resulting in a remainder of 28.
The next digit of our result is 2. 
Result so far: 5569.2
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:
280 divided by 31 is 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 5569.29
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.

Moving on to step 9:
31 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 5569.29
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.

On to step 10:
When dividing 100 by 31, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 5569.2903
If we subtract 93 from 100, we 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.

On to step 11:
31 goes into 70 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 5569.29032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
The number 31 fits into 80 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 5569.290322
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 5569.290322 with a remaining 1.8e-06.
