We look at the division of 31106789 by 105 
We want to divide 31106789 by 105.

Let's proceed to step 1:
If we divide 3 by 105, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 105

Step 2:
105 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Take the next digit (1) from the dividend and append it to 31, then repeat: 311 / 105

Moving on to step 3:
311 divided by 105 is 2 with a remainder of 101.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 210 from 311 and we're left with 101.
Grab the next digit (0) from the dividend, add it to 101, then carry on: 1010 / 105

On to step 4:
105 can be fit into 1010 9 times, resulting in a remainder of 65.
Put 9 as the next digit of the answer. 
Result so far: 29.0
The remainder is 65 after subtracting 945 from 1010.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 105

On to step 5:
If we divide 656 by 105, we get 6 and a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 296.0
If we take 630 away from 656, we end up with 26.
Bring next digit (7) of the dividend behind the 26 and repeat the process: 267 / 105

Advancing to step 6:
105 can be fit into 267 2 times, resulting in a remainder of 57.
Write down 2 as next digit of the result. 
Result so far: 2962.0
If we take 210 away from 267, we end up with 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 105

Step 7:
105 can be fit into 578 5 times, resulting in a remainder of 53.
The next digit of our result is 5. 
Result so far: 29625.0
Subtract 525 from 578 to get 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 105

Advancing to step 8:
105 goes into 539 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 296255.0
Deduct 525 from 539 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
When dividing 140 by 105, we get 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 296255.1
Subtract 105 from 140 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
The number 105 fits into 350 3 times, leaving a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 296255.13
If we take 315 away from 350, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
105 can be fit into 350 3 times, resulting in a remainder of 35.
The next digit of our result is 3. 
Result so far: 296255.133
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 296255.133, with a leftover of 0.0035.
