We divide 243559 by 31
We want to divide 243559 by 31.

On to step 1:
31 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 31

Advancing to step 2:
If we divide 24 by 31, we get 0 and a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 31

Step 3:
If we divide 243 by 31, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 217 from 243, we get 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 31

On to step 4:
When dividing 265 by 31, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 17 after subtracting 248 from 265.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 31

Going ahead to step 5:
31 can be fit into 175 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 785.0
Subtracting 155 from 175 leaves us with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 31

Advancing to step 6:
When dividing 209 by 31, we get 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 7856.0
If we subtract 186 from 209, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 7:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7856.7
Subtracting 217 from 230 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
31 goes into 130 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 7856.74
If we subtract 124 from 130, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
The number 31 fits into 60 1 times, leaving a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 7856.741
If we take 31 away from 60, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
When dividing 290 by 31, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 7856.7419
The remainder is 11 after subtracting 279 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
When dividing 110 by 31, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 7856.74193
Deduct 93 from 110 and we're left 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.

Advancing to step 12:
When dividing 170 by 31, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7856.741935
Deduct 155 from 170 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
31 goes into 150 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 7856.7419354
Deduct 124 from 150 and we're left 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 14:
260 divided by 31 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 7856.74193548
Deduct 248 from 260 and we're left 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.

After the division, we end up with 7856.74193548 and a remainder of 1.2e-08.
