We look at the division of 65121099 by 212 
We're looking to find how many times 212 goes into 65121099.

On to step 1:
212 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 212

Step 2:
212 can be fit into 65 0 times, resulting in a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 212

Advancing to step 3:
212 can be fit into 651 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 636 from 651 to get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 212

Going ahead to step 4:
If we divide 152 by 212, we get 0 and a remainder of 152.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Subtracting 0 from 152 leaves us with 152.
Take the next digit (1) from the dividend and append it to 152, then repeat: 1521 / 212

On to step 5:
212 can be fit into 1521 7 times, resulting in a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
The remainder is 37 after subtracting 1484 from 1521.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 212

Step 6:
When dividing 370 by 212, we get 1 with a remainder of 158.
Record the quotient 1 as the next digit in the result. 
Result so far: 3071.0
Subtract 212 from 370 to get 158.
Bring next digit (9) of the dividend behind the 158 and repeat the process: 1589 / 212

Step 7:
1589 divided by 212 is 7 with a remainder of 105.
Write down 7 as next digit of the result. 
Result so far: 30717.0
Subtract 1484 from 1589 to get 105.
Include the next digit (9) from the dividend after 105, then repeat: 1059 / 212

Moving on to step 8:
212 can be fit into 1059 4 times, resulting in a remainder of 211.
The next digit of our result is 4. 
Result so far: 307174.0
Deduct 848 from 1059 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Advancing to step 9:
2110 divided by 212 is 9 with a remainder of 202.
Put 9 as the next digit of the answer. 
Result so far: 307174.9
Subtracting 1908 from 2110 leaves us with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 10:
When dividing 2020 by 212, we get 9 with a remainder of 112.
The number 9 becomes the next digit in our result. 
Result so far: 307174.99
Subtracting 1908 from 2020 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 307174.99, with a leftover of 0.112.
