We divide 21628809 by 412
Our goal is to divide 21628809 by 412.

Step 1:
The number 412 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 412

Going ahead to step 2:
The number 412 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
The remainder is 21 after subtracting 0 from 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 412

Going ahead to step 3:
412 goes into 216 0 times with a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 216 to get 216.
Take the next digit (2) from the dividend and append it to 216, then repeat: 2162 / 412

Step 4:
412 can be fit into 2162 5 times, resulting in a remainder of 102.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 2060 from 2162 and we're left with 102.
Bring next digit (8) of the dividend behind the 102 and repeat the process: 1028 / 412

Advancing to step 5:
412 goes into 1028 2 times with a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 52.0
The remainder is 204 after subtracting 824 from 1028.
Bring next digit (8) of the dividend behind the 204 and repeat the process: 2048 / 412

Step 6:
The number 412 fits into 2048 4 times, leaving a remainder of 400.
Write down 4 as next digit of the result. 
Result so far: 524.0
Deduct 1648 from 2048 and we're left with 400.
Grab the next digit (0) from the dividend, add it to 400, then carry on: 4000 / 412

Step 7:
4000 divided by 412 is 9 with a remainder of 292.
Write down 9 as next digit of the result. 
Result so far: 5249.0
The remainder is 292 after subtracting 3708 from 4000.
Bring next digit (9) of the dividend behind the 292 and repeat the process: 2929 / 412

Advancing to step 8:
The number 412 fits into 2929 7 times, leaving a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 52497.0
The remainder is 45 after subtracting 2884 from 2929.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
412 can be fit into 450 1 times, resulting in a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 52497.1
The remainder is 38 after subtracting 412 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
380 divided by 412 is 0 with a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 52497.1
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 11:
412 goes into 3800 9 times with a remainder of 92.
Record the quotient 9 as the next digit in the result. 
Result so far: 52497.109
Deduct 3708 from 3800 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 12:
412 goes into 920 2 times with a remainder of 96.
The next digit of our result is 2. 
Result so far: 52497.1092
If we subtract 824 from 920, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
412 goes into 960 2 times with a remainder of 136.
The next digit of our result is 2. 
Result so far: 52497.10922
If we take 824 away from 960, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 52497.10922 with a remainder of 0.000136.
