223635 divided by 31 
We're looking to find how many times 31 goes into 223635.

Going ahead to step 1:
2 divided by 31 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 31

Going ahead to step 2:
If we divide 22 by 31, we get 0 and a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 31

Advancing to step 3:
31 can be fit into 223 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 217 from 223 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 31

On to step 4:
When dividing 66 by 31, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 62 from 66, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 31

On to step 5:
The number 31 fits into 43 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 721.0
Deduct 31 from 43 and we're left with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 31

Moving on to step 6:
125 divided by 31 is 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 7214.0
Subtract 124 from 125 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.

Going ahead to step 7:
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: 7214.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 31, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 7214.03
Deduct 93 from 100 and we're left 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.

Going ahead to step 9:
The number 31 fits into 70 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 7214.032
If we take 62 away from 70, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 31, we get 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 7214.0322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 7214.0322 and a remainder of 0.00018.
