If we divide 869 by 212, we get 4 and a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 24.0
The remainder is 21 after subtracting 848 from 869.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 212

Advancing to step 5:
If we divide 212 by 212, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 241.0
Subtract 212 from 212 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 212

Step 6:
212 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2410.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 212

Step 7:
When dividing 7 by 212, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 24100.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 212

On to step 8:
When dividing 77 by 212, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 241000.0
Subtract 0 from 77 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 9:
212 goes into 770 3 times with a remainder of 134.
The next digit of our result is 3. 
Result so far: 241000.3
Deduct 636 from 770 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
When dividing 1340 by 212, we get 6 with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 241000.36
Deduct 1272 from 1340 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
When dividing 680 by 212, we get 3 with a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 241000.363
Deduct 636 from 680 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
212 can be fit into 440 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 241000.3632
Subtract 424 from 440 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
The number 212 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 241000.3632
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
212 goes into 1600 7 times with a remainder of 116.
Record the quotient 7 as the next digit in the result. 
Result so far: 241000.363207
Deduct 1484 from 1600 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 15:
1160 divided by 212 is 5 with a remainder of 100.
The next digit of our result is 5. 
Result so far: 241000.3632075
Subtract 1060 from 1160 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 16:
212 can be fit into 1000 4 times, resulting in a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 241000.36320754
If we subtract 848 from 1000, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final result is 241000.36320754 with a remainder of 1.52e-07.
