We look at the division of 21923510 by 826 
We're looking to find how many times 826 goes into 21923510.

Step 1:
The number 826 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 826

Moving on to step 2:
826 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
Deduct 0 from 21 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 826

Going ahead to step 3:
When dividing 219 by 826, we get 0 with a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 219 and we're left with 219.
Fetch the next digit (2) from the dividend, attach it to 219 and continue: 2192 / 826

Going ahead to step 4:
826 goes into 2192 2 times with a remainder of 540.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1652 from 2192 and we're left with 540.
Include the next digit (3) from the dividend after 540, then repeat: 5403 / 826

On to step 5:
5403 divided by 826 is 6 with a remainder of 447.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 4956 from 5403 to get 447.
Grab the next digit (5) from the dividend, add it to 447, then carry on: 4475 / 826

On to step 6:
826 can be fit into 4475 5 times, resulting in a remainder of 345.
Use 5 as the next digit of our solution. 
Result so far: 265.0
Subtract 4130 from 4475 to get 345.
Take the next digit (1) from the dividend and append it to 345, then repeat: 3451 / 826

Advancing to step 7:
826 can be fit into 3451 4 times, resulting in a remainder of 147.
Put 4 as the next digit of the answer. 
Result so far: 2654.0
If we subtract 3304 from 3451, we get 147.
Take the next digit (0) from the dividend and append it to 147, then repeat: 1470 / 826

Step 8:
The number 826 fits into 1470 1 times, leaving a remainder of 644.
Write down 1 as next digit of the result. 
Result so far: 26541.0
If we take 826 away from 1470, we end up with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 9:
If we divide 6440 by 826, we get 7 and a remainder of 658.
Put 7 as the next digit of the answer. 
Result so far: 26541.7
If we take 5782 away from 6440, we end up with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Step 10:
When dividing 6580 by 826, we get 7 with a remainder of 798.
The number 7 becomes the next digit in our result. 
Result so far: 26541.77
If we take 5782 away from 6580, we end up with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

After the division, we end up with 26541.77 and a remainder of 0.798.
