We look at the division of 343579 by 31 
We want to divide 343579 by 31.

Moving on to step 1:
31 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 31

Going ahead to step 2:
The number 31 fits into 34 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 31 from 34 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 31

Advancing to step 3:
33 divided by 31 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 31 from 33, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 31

Advancing to step 4:
25 divided by 31 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 110.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 31

Moving on to step 5:
31 goes into 257 8 times with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 1108.0
Deduct 248 from 257 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 31

On to step 6:
When dividing 99 by 31, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 11083.0
Deduct 93 from 99 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
31 can be fit into 60 1 times, resulting in a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 11083.1
The remainder is 29 after subtracting 31 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 8:
If we divide 290 by 31, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 11083.19
Deduct 279 from 290 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
When dividing 110 by 31, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 11083.193
If we take 93 away from 110, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
31 goes into 170 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 11083.1935
The remainder is 15 after subtracting 155 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
The number 31 fits into 150 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 11083.19354
Subtracting 124 from 150 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
When dividing 260 by 31, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 11083.193548
Subtracting 248 from 260 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
If we divide 120 by 31, we get 3 and a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 11083.1935483
If we take 93 away from 120, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 14:
If we divide 270 by 31, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 11083.19354838
Subtracting 248 from 270 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

After the division, we end up with 11083.19354838 and a remainder of 2.2e-08.
