31321718 ÷ 235 
Our goal is to divide 31321718 by 235.

On to step 1:
When dividing 3 by 235, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 235

Going ahead to step 2:
31 divided by 235 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 235

Step 3:
When dividing 313 by 235, we get 1 with a remainder of 78.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 235 from 313 and we're left with 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 235

Step 4:
235 can be fit into 782 3 times, resulting in a remainder of 77.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 705 from 782 and we're left with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 235

Going ahead to step 5:
When dividing 771 by 235, we get 3 with a remainder of 66.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
Subtracting 705 from 771 leaves us with 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 235

Going ahead to step 6:
235 goes into 667 2 times with a remainder of 197.
The number 2 becomes the next digit in our result. 
Result so far: 1332.0
If we take 470 away from 667, we end up with 197.
Take the next digit (1) from the dividend and append it to 197, then repeat: 1971 / 235

Moving on to step 7:
235 can be fit into 1971 8 times, resulting in a remainder of 91.
Write down 8 as next digit of the result. 
Result so far: 13328.0
Subtracting 1880 from 1971 leaves us with 91.
Grab the next digit (8) from the dividend, add it to 91, then carry on: 918 / 235

Step 8:
235 goes into 918 3 times with a remainder of 213.
Write down 3 as next digit of the result. 
Result so far: 133283.0
The remainder is 213 after subtracting 705 from 918.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 9:
If we divide 2130 by 235, we get 9 and a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 133283.9
Subtracting 2115 from 2130 leaves us 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 10:
150 divided by 235 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 133283.9
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
The number 235 fits into 1500 6 times, leaving a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 133283.906
Deduct 1410 from 1500 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 12:
900 divided by 235 is 3 with a remainder of 195.
The number 3 becomes the next digit in our result. 
Result so far: 133283.9063
Subtract 705 from 900 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 13:
235 goes into 1950 8 times with a remainder of 70.
The next digit of our result is 8. 
Result so far: 133283.90638
Deduct 1880 from 1950 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
700 divided by 235 is 2 with a remainder of 230.
Put 2 as the next digit of the answer. 
Result so far: 133283.906382
The remainder is 230 after subtracting 470 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 15:
235 can be fit into 2300 9 times, resulting in a remainder of 185.
Use 9 as the next digit of our solution. 
Result so far: 133283.9063829
If we take 2115 away from 2300, we end up with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 16:
235 can be fit into 1850 7 times, resulting in a remainder of 205.
The next digit of our result is 7. 
Result so far: 133283.90638297
If we take 1645 away from 1850, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The final outcome is 133283.90638297, with a leftover of 2.05e-07.
