We divide 209781 by 31
Our goal is to divide 209781 by 31.

Advancing to step 1:
The number 31 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 31

Advancing to step 2:
31 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 31

Moving on to step 3:
If we divide 209 by 31, we get 6 and a remainder of 23.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 186 away from 209, we end up with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 31

Advancing to step 4:
The number 31 fits into 237 7 times, leaving a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 67.0
If we take 217 away from 237, we end up with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 31

Step 5:
31 goes into 208 6 times with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 676.0
Subtract 186 from 208 to get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 31

Advancing to step 6:
31 goes into 221 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 6767.0
If we take 217 away from 221, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 31, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 6767.1
Subtracting 31 from 40 leaves us 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.

On to step 8:
31 goes into 90 2 times with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 6767.12
Subtracting 62 from 90 leaves us 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 9:
280 divided by 31 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 6767.129
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.

Step 10:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6767.129
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.

Step 11:
100 divided by 31 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 6767.12903
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
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: 6767.129032
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 13:
The number 31 fits into 80 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 6767.1290322
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.

The final outcome is 6767.1290322, with a leftover of 1.8e-07.
