We look at the division of 108069 by 31 
We want to figure out the number of times 108069 can be divided by 31.

Moving on to step 1:
31 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 31

Advancing to step 2:
When dividing 10 by 31, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 31

Moving on to step 3:
The number 31 fits into 108 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 93 from 108 and we're left with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 31

Going ahead to step 4:
150 divided by 31 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 124 away from 150, we end up with 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 31

Step 5:
31 can be fit into 266 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 348.0
Subtracting 248 from 266 leaves us with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 31

Step 6:
189 divided by 31 is 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 3486.0
If we take 186 away from 189, 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.

Going ahead to step 7:
30 divided by 31 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 3486.0
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.

Moving on to step 8:
When dividing 300 by 31, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 3486.09
If we take 279 away from 300, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
When dividing 210 by 31, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 3486.096
Subtracting 186 from 210 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
When dividing 240 by 31, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 3486.0967
If we take 217 away from 240, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
31 goes into 230 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 3486.09677
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 3486.09677 with a remaining 1.3e-05.
