Let's divide 21683103 by 212
We want to divide 21683103 by 212.

Advancing to step 1:
The number 212 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 212

Let's proceed to step 2:
The number 212 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 212

Step 3:
212 goes into 216 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 212 away from 216, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 212

Step 4:
48 divided by 212 is 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 48 after subtracting 0 from 48.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 212

On to step 5:
The number 212 fits into 483 2 times, leaving a remainder of 59.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
If we take 424 away from 483, we end up with 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 212

On to step 6:
212 can be fit into 591 2 times, resulting in a remainder of 167.
The next digit of our result is 2. 
Result so far: 1022.0
Subtracting 424 from 591 leaves us with 167.
Grab the next digit (0) from the dividend, add it to 167, then carry on: 1670 / 212

On to step 7:
212 can be fit into 1670 7 times, resulting in a remainder of 186.
The number 7 becomes the next digit in our result. 
Result so far: 10227.0
If we subtract 1484 from 1670, we get 186.
Include the next digit (3) from the dividend after 186, then repeat: 1863 / 212

Moving on to step 8:
1863 divided by 212 is 8 with a remainder of 167.
Put 8 as the next digit of the answer. 
Result so far: 102278.0
Subtract 1696 from 1863 to get 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:
The number 212 fits into 1670 7 times, leaving a remainder of 186.
Put 7 as the next digit of the answer. 
Result so far: 102278.7
The remainder is 186 after subtracting 1484 from 1670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 10:
212 goes into 1860 8 times with a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 102278.78
Subtracting 1696 from 1860 leaves us with 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:
If we divide 1640 by 212, we get 7 and a remainder of 156.
The number 7 becomes the next digit in our result. 
Result so far: 102278.787
Deduct 1484 from 1640 and we're left 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.

Going ahead to step 12:
1560 divided by 212 is 7 with a remainder of 76.
The number 7 becomes the next digit in our result. 
Result so far: 102278.7877
Deduct 1484 from 1560 and we're left with 76.
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 102278.7877 with a remainder of 0.00076.
