223643 ÷ 31 
Let's see how many times 31 fits into 223643.

Step 1:
The number 31 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 31

Going ahead to step 2:
31 can be fit into 22 0 times, resulting in a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 31

On to step 3:
When dividing 223 by 31, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 217 away from 223, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 31

Let's proceed to step 4:
31 goes into 66 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Subtract 62 from 66 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 31

Going ahead to step 5:
31 can be fit into 44 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 721.0
Subtracting 31 from 44 leaves us with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 31

Let's proceed to step 6:
31 can be fit into 133 4 times, resulting in a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 7214.0
Deduct 124 from 133 and we're left 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.

Let's proceed to step 7:
When dividing 90 by 31, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 7214.2
If we take 62 away from 90, we end up 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.

Moving on to step 8:
280 divided by 31 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 7214.29
Subtract 279 from 280 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 7214.29
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 31 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 7214.2903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 7214.29032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
If we divide 80 by 31, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 7214.290322
If we take 62 away from 80, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 7214.290322, and the remainder is 1.8e-06.
