31311562 ÷ 172 
We're looking to find how many times 172 goes into 31311562.

Step 1:
172 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 172

Let's proceed to step 2:
When dividing 31 by 172, we get 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 172

Moving on to step 3:
172 goes into 313 1 times with a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 172 away from 313, we end up with 141.
Bring next digit (1) of the dividend behind the 141 and repeat the process: 1411 / 172

Step 4:
172 goes into 1411 8 times with a remainder of 35.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 1376 from 1411 and we're left with 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 172

Step 5:
When dividing 351 by 172, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 182.0
Subtracting 344 from 351 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 172

Going ahead to step 6:
172 goes into 75 0 times with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 1820.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 172

Moving on to step 7:
756 divided by 172 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 18204.0
Subtract 688 from 756 to get 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 172

Going ahead to step 8:
682 divided by 172 is 3 with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 182043.0
If we subtract 516 from 682, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 9:
1660 divided by 172 is 9 with a remainder of 112.
Put 9 as the next digit of the answer. 
Result so far: 182043.9
If we subtract 1548 from 1660, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 10:
When dividing 1120 by 172, we get 6 with a remainder of 88.
The next digit of our result is 6. 
Result so far: 182043.96
Deduct 1032 from 1120 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 11:
When dividing 880 by 172, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 182043.965
Deduct 860 from 880 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
200 divided by 172 is 1 with a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 182043.9651
Deduct 172 from 200 and we're left with 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 13:
When dividing 280 by 172, we get 1 with a remainder of 108.
The number 1 becomes the next digit in our result. 
Result so far: 182043.96511
If we subtract 172 from 280, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

In conclusion, the division gives 182043.96511 with a balance of 0.000108.
