Let's divide 21074566 by 812
Our goal is to divide 21074566 by 812.

Going ahead to step 1:
812 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
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 812

Moving on to step 2:
21 divided by 812 is 0 with 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.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 812

Moving on to step 3:
210 divided by 812 is 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Grab the next digit (7) from the dividend, add it to 210, then carry on: 2107 / 812

Moving on to step 4:
812 goes into 2107 2 times with a remainder of 483.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 483 after subtracting 1624 from 2107.
Bring next digit (4) of the dividend behind the 483 and repeat the process: 4834 / 812

Advancing to step 5:
When dividing 4834 by 812, we get 5 with a remainder of 774.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 4060 from 4834, we get 774.
Grab the next digit (5) from the dividend, add it to 774, then carry on: 7745 / 812

Let's proceed to step 6:
812 can be fit into 7745 9 times, resulting in a remainder of 437.
Use 9 as the next digit of our solution. 
Result so far: 259.0
The remainder is 437 after subtracting 7308 from 7745.
Take the next digit (6) from the dividend and append it to 437, then repeat: 4376 / 812

On to step 7:
When dividing 4376 by 812, we get 5 with a remainder of 316.
Put 5 as the next digit of the answer. 
Result so far: 2595.0
Subtracting 4060 from 4376 leaves us with 316.
Bring next digit (6) of the dividend behind the 316 and repeat the process: 3166 / 812

Let's proceed to step 8:
3166 divided by 812 is 3 with a remainder of 730.
Record the quotient 3 as the next digit in the result. 
Result so far: 25953.0
The remainder is 730 after subtracting 2436 from 3166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 9:
If we divide 7300 by 812, we get 8 and a remainder of 804.
The number 8 becomes the next digit in our result. 
Result so far: 25953.8
Subtracting 6496 from 7300 leaves us with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Let's proceed to step 10:
812 goes into 8040 9 times with a remainder of 732.
Write down 9 as next digit of the result. 
Result so far: 25953.89
The remainder is 732 after subtracting 7308 from 8040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Moving on to step 11:
If we divide 7320 by 812, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 25953.899
If we subtract 7308 from 7320, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 25953.899 with a balance of 0.0012.
