Let's divide 243794 by 31
Our goal is to divide 243794 by 31.

On to step 1:
31 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 31

On to step 2:
If we divide 24 by 31, we get 0 and a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 31

Step 3:
31 can be fit into 243 7 times, resulting in a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 217 from 243 to get 26.
Take the next digit (7) from the dividend and append it to 26, then repeat: 267 / 31

Step 4:
When dividing 267 by 31, we get 8 with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
The remainder is 19 after subtracting 248 from 267.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 31

Going ahead to step 5:
When dividing 199 by 31, we get 6 with a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 786.0
If we subtract 186 from 199, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 31

Going ahead to step 6:
The number 31 fits into 134 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 7864.0
If we subtract 124 from 134, 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 7:
When dividing 100 by 31, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 7864.3
If we take 93 away from 100, we end up 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.

On to step 8:
The number 31 fits into 70 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 7864.32
Deduct 62 from 70 and we're left 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 9:
31 can be fit into 80 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 7864.322
Subtract 62 from 80 to get 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 final outcome is 7864.322, with a leftover of 0.0018.
