We're dividing 84112 by 31 
We're looking to find how many times 31 goes into 84112.

Moving on to step 1:
If we divide 8 by 31, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 31

Moving on to step 2:
If we divide 84 by 31, we get 2 and a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 62 away from 84, we end up with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 31

Step 3:
When dividing 221 by 31, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 217 away from 221, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 31

Advancing to step 4:
When dividing 41 by 31, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
Deduct 31 from 41 and we're left with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 31

Let's proceed to step 5:
When dividing 102 by 31, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 2713.0
Subtract 93 from 102 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 6:
If we divide 90 by 31, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 2713.2
If we take 62 away from 90, we end up 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.

Moving on to step 7:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 2713.29
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.

Going ahead to step 8:
When dividing 10 by 31, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 2713.29
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.

Step 9:
100 divided by 31 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 2713.2903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
If we divide 70 by 31, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 2713.29032
Subtracting 62 from 70 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
31 can be fit into 80 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 2713.290322
Subtracting 62 from 80 leaves us 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.

In conclusion, the division gives 2713.290322 with a balance of 1.8e-06.
