210615 ÷ 31 
We want to divide 210615 by 31.

Let's proceed to step 1:
If we divide 2 by 31, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 31

Going ahead to step 2:
If we divide 21 by 31, we get 0 and a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 31

Going ahead to step 3:
When dividing 210 by 31, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 186 from 210 and we're left with 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 31

Step 4:
31 goes into 246 7 times with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we subtract 217 from 246, we get 29.
Fetch the next digit (1) from the dividend, attach it to 29 and continue: 291 / 31

Step 5:
If we divide 291 by 31, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 679.0
If we subtract 279 from 291, we get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 31

On to step 6:
31 can be fit into 125 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 6794.0
Deduct 124 from 125 and we're left with 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:
10 divided by 31 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 6794.0
The remainder is 10 after subtracting 0 from 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 8:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 6794.03
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.

Advancing to step 9:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 6794.032
Subtracting 62 from 70 leaves us 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.

Step 10:
80 divided by 31 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 6794.0322
Subtracting 62 from 80 leaves us with 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 6794.0322, with a leftover of 0.00018.
