We're dividing 16521115 by 212 
Let's see how many times 212 fits into 16521115.

Advancing to step 1:
The number 212 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 212

Moving on to step 2:
When dividing 16 by 212, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 212

On to step 3:
212 goes into 165 0 times with a remainder of 165.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 165, we end up with 165.
Include the next digit (2) from the dividend after 165, then repeat: 1652 / 212

Advancing to step 4:
1652 divided by 212 is 7 with a remainder of 168.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 1484 from 1652 and we're left with 168.
Bring next digit (1) of the dividend behind the 168 and repeat the process: 1681 / 212

Moving on to step 5:
212 goes into 1681 7 times with a remainder of 197.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we take 1484 away from 1681, we end up with 197.
Append the next digit (1) from the dividend to 197 and continue with: 1971 / 212

Let's proceed to step 6:
If we divide 1971 by 212, we get 9 and a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 779.0
If we take 1908 away from 1971, we end up with 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 212

Going ahead to step 7:
The number 212 fits into 631 2 times, leaving a remainder of 207.
The next digit of our result is 2. 
Result so far: 7792.0
The remainder is 207 after subtracting 424 from 631.
Take the next digit (5) from the dividend and append it to 207, then repeat: 2075 / 212

Moving on to step 8:
When dividing 2075 by 212, we get 9 with a remainder of 167.
The next digit of our result is 9. 
Result so far: 77929.0
If we take 1908 away from 2075, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 9:
1670 divided by 212 is 7 with a remainder of 186.
Put 7 as the next digit of the answer. 
Result so far: 77929.7
If we subtract 1484 from 1670, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 10:
When dividing 1860 by 212, we get 8 with a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 77929.78
If we subtract 1696 from 1860, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 11:
When dividing 1640 by 212, we get 7 with a remainder of 156.
Record the quotient 7 as the next digit in the result. 
Result so far: 77929.787
If we take 1484 away from 1640, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 12:
212 goes into 1560 7 times with a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 77929.7877
The remainder is 76 after subtracting 1484 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 77929.7877 with a remainder of 0.00076.
