We're dividing 543909 by 31 
We're looking to find how many times 31 goes into 543909.

Going ahead to step 1:
When dividing 5 by 31, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 31

Advancing to step 2:
31 goes into 54 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 31 away from 54, we end up with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 31

Moving on to step 3:
When dividing 233 by 31, we get 7 with a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 217 from 233, we get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 31

Let's proceed to step 4:
If we divide 169 by 31, we get 5 and a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 175.0
If we take 155 away from 169, we end up with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 31

Advancing to step 5:
When dividing 140 by 31, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1754.0
Deduct 124 from 140 and we're left with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 31

Moving on to step 6:
169 divided by 31 is 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 17545.0
If we take 155 away from 169, we end up 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.

On to step 7:
If we divide 140 by 31, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 17545.4
If we take 124 away from 140, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
31 goes into 160 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 17545.45
If we take 155 away from 160, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
The number 31 fits into 50 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 17545.451
If we take 31 away from 50, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
31 goes into 190 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 17545.4516
Subtracting 186 from 190 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
When dividing 40 by 31, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 17545.45161
Subtracting 31 from 40 leaves us with 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 12:
31 can be fit into 90 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 17545.451612
Deduct 62 from 90 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.

Let's proceed to step 13:
31 goes into 280 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 17545.4516129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 17545.4516129
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 17545.4516129, and the remainder is 1e-08.
