We look at the division of 21392046 by 212 
We want to divide 21392046 by 212.

Step 1:
2 divided by 212 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 212

Going ahead to step 2:
The number 212 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 212

Going ahead to step 3:
The number 212 fits into 213 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 212 from 213 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 212

On to step 4:
212 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 212

Advancing to step 5:
192 divided by 212 is 0 with a remainder of 192.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we subtract 0 from 192, we get 192.
Fetch the next digit (0) from the dividend, attach it to 192 and continue: 1920 / 212

On to step 6:
212 can be fit into 1920 9 times, resulting in a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 1009.0
Subtract 1908 from 1920 to get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 212

Advancing to step 7:
212 goes into 124 0 times with a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 10090.0
Deduct 0 from 124 and we're left with 124.
Take the next digit (6) from the dividend and append it to 124, then repeat: 1246 / 212

Step 8:
1246 divided by 212 is 5 with a remainder of 186.
The number 5 becomes the next digit in our result. 
Result so far: 100905.0
If we take 1060 away from 1246, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 9:
When dividing 1860 by 212, we get 8 with a remainder of 164.
The number 8 becomes the next digit in our result. 
Result so far: 100905.8
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.

On to step 10:
The number 212 fits into 1640 7 times, leaving a remainder of 156.
Write down 7 as next digit of the result. 
Result so far: 100905.87
The remainder is 156 after subtracting 1484 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 11:
212 can be fit into 1560 7 times, resulting in a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 100905.877
Subtract 1484 from 1560 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 100905.877 with a remaining 0.0076.
