We look at the division of 21212164 by 364 
We want to divide 21212164 by 364.

Step 1:
364 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 364

Step 2:
364 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 364

On to step 3:
When dividing 212 by 364, we get 0 with a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Bring next digit (1) of the dividend behind the 212 and repeat the process: 2121 / 364

Going ahead to step 4:
The number 364 fits into 2121 5 times, leaving a remainder of 301.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 1820 away from 2121, we end up with 301.
Include the next digit (2) from the dividend after 301, then repeat: 3012 / 364

Going ahead to step 5:
364 goes into 3012 8 times with a remainder of 100.
The next digit of our result is 8. 
Result so far: 58.0
Subtract 2912 from 3012 to get 100.
Bring next digit (1) of the dividend behind the 100 and repeat the process: 1001 / 364

Advancing to step 6:
364 goes into 1001 2 times with a remainder of 273.
Write down 2 as next digit of the result. 
Result so far: 582.0
The remainder is 273 after subtracting 728 from 1001.
Include the next digit (6) from the dividend after 273, then repeat: 2736 / 364

Step 7:
364 goes into 2736 7 times with a remainder of 188.
Put 7 as the next digit of the answer. 
Result so far: 5827.0
Subtracting 2548 from 2736 leaves us with 188.
Bring next digit (4) of the dividend behind the 188 and repeat the process: 1884 / 364

Going ahead to step 8:
The number 364 fits into 1884 5 times, leaving a remainder of 64.
The number 5 becomes the next digit in our result. 
Result so far: 58275.0
The remainder is 64 after subtracting 1820 from 1884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
When dividing 640 by 364, we get 1 with a remainder of 276.
The number 1 becomes the next digit in our result. 
Result so far: 58275.1
Deduct 364 from 640 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 10:
364 goes into 2760 7 times with a remainder of 212.
Put 7 as the next digit of the answer. 
Result so far: 58275.17
If we subtract 2548 from 2760, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 11:
When dividing 2120 by 364, we get 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 58275.175
If we take 1820 away from 2120, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 12:
The number 364 fits into 3000 8 times, leaving a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 58275.1758
The remainder is 88 after subtracting 2912 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 13:
If we divide 880 by 364, we get 2 and a remainder of 152.
The next digit of our result is 2. 
Result so far: 58275.17582
The remainder is 152 after subtracting 728 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 14:
1520 divided by 364 is 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 58275.175824
Subtracting 1456 from 1520 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
364 can be fit into 640 1 times, resulting in a remainder of 276.
The next digit of our result is 1. 
Result so far: 58275.1758241
Deduct 364 from 640 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 16:
If we divide 2760 by 364, we get 7 and a remainder of 212.
Put 7 as the next digit of the answer. 
Result so far: 58275.17582417
Subtracting 2548 from 2760 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

In conclusion, the division gives 58275.17582417 with a balance of 2.12e-07.
