235 can be fit into 2217 9 times, resulting in a remainder of 102.
The next digit of our result is 9. 
Result so far: 389.0
Subtract 2115 from 2217 to get 102.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 235

Going ahead to step 6:
235 can be fit into 1023 4 times, resulting in a remainder of 83.
Use 4 as the next digit of our solution. 
Result so far: 3894.0
Subtracting 940 from 1023 leaves us with 83.
Append the next digit (9) from the dividend to 83 and continue with: 839 / 235

Step 7:
839 divided by 235 is 3 with a remainder of 134.
The next digit of our result is 3. 
Result so far: 38943.0
The remainder is 134 after subtracting 705 from 839.
Take the next digit (0) from the dividend and append it to 134, then repeat: 1340 / 235

Step 8:
The number 235 fits into 1340 5 times, leaving a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 389435.0
If we subtract 1175 from 1340, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 9:
1650 divided by 235 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 389435.7
Subtract 1645 from 1650 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
235 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 389435.7
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
The number 235 fits into 500 2 times, leaving a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 389435.702
Deduct 470 from 500 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
235 goes into 300 1 times with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 389435.7021
The remainder is 65 after subtracting 235 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 13:
The number 235 fits into 650 2 times, leaving a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 389435.70212
Subtract 470 from 650 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 14:
1800 divided by 235 is 7 with a remainder of 155.
The number 7 becomes the next digit in our result. 
Result so far: 389435.702127
Subtract 1645 from 1800 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 15:
235 can be fit into 1550 6 times, resulting in a remainder of 140.
Put 6 as the next digit of the answer. 
Result so far: 389435.7021276
The remainder is 140 after subtracting 1410 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
1400 divided by 235 is 5 with a remainder of 225.
The number 5 becomes the next digit in our result. 
Result so far: 389435.70212765
Subtracting 1175 from 1400 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The quotient of the division is 389435.70212765, and the remainder is 2.25e-07.
