We're dividing 212537 by 15 
We want to divide 212537 by 15.

Step 1:
The number 15 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.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 15

Moving on to step 2:
21 divided by 15 is 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 15 from 21 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 15

Advancing to step 3:
If we divide 62 by 15, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 60 from 62 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 15

Moving on to step 4:
25 divided by 15 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Subtract 15 from 25 to get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 15

On to step 5:
15 can be fit into 103 6 times, resulting in a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 1416.0
Subtract 90 from 103 to get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 15

Moving on to step 6:
15 can be fit into 137 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 14169.0
Subtracting 135 from 137 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 15 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 14169.1
Subtracting 15 from 20 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 14169.13
If we subtract 45 from 50, we 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.

Going ahead to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 14169.133
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 14169.133, with a leftover of 0.0005.
