96621209 ÷ 212 
We want to figure out the number of times 96621209 can be divided by 212.

Going ahead to step 1:
212 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 212

On to step 2:
212 can be fit into 96 0 times, resulting in a remainder of 96.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 96 and we're left with 96.
Append the next digit (6) from the dividend to 96 and continue with: 966 / 212

Let's proceed to step 3:
If we divide 966 by 212, we get 4 and a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 848 from 966 leaves us with 118.
Include the next digit (2) from the dividend after 118, then repeat: 1182 / 212

Step 4:
212 can be fit into 1182 5 times, resulting in a remainder of 122.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 1060 from 1182 and we're left with 122.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 212

Moving on to step 5:
212 goes into 1221 5 times with a remainder of 161.
Use 5 as the next digit of our solution. 
Result so far: 455.0
If we take 1060 away from 1221, we end up with 161.
Grab the next digit (2) from the dividend, add it to 161, then carry on: 1612 / 212

On to step 6:
The number 212 fits into 1612 7 times, leaving a remainder of 128.
Write down 7 as next digit of the result. 
Result so far: 4557.0
If we take 1484 away from 1612, we end up with 128.
Fetch the next digit (0) from the dividend, attach it to 128 and continue: 1280 / 212

Moving on to step 7:
If we divide 1280 by 212, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 45576.0
Subtract 1272 from 1280 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 212

Moving on to step 8:
212 can be fit into 89 0 times, resulting in a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 455760.0
Deduct 0 from 89 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 9:
890 divided by 212 is 4 with a remainder of 42.
The next digit of our result is 4. 
Result so far: 455760.4
Deduct 848 from 890 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
When dividing 420 by 212, we get 1 with a remainder of 208.
Put 1 as the next digit of the answer. 
Result so far: 455760.41
If we subtract 212 from 420, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 11:
The number 212 fits into 2080 9 times, leaving a remainder of 172.
The next digit of our result is 9. 
Result so far: 455760.419
Subtracting 1908 from 2080 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 12:
1720 divided by 212 is 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 455760.4198
Deduct 1696 from 1720 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
212 goes into 240 1 times with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 455760.41981
If we take 212 away from 240, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 14:
The number 212 fits into 280 1 times, leaving a remainder of 68.
The next digit of our result is 1. 
Result so far: 455760.419811
If we subtract 212 from 280, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

In conclusion, the division gives 455760.419811 with a balance of 6.8e-06.
