We look at the division of 21763889 by 819 
We want to divide 21763889 by 819.

Step 1:
819 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
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 819

Advancing to step 2:
The number 819 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
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 819

On to step 3:
If we divide 217 by 819, we get 0 and a remainder of 217.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 217 to get 217.
Append the next digit (6) from the dividend to 217 and continue with: 2176 / 819

Let's proceed to step 4:
The number 819 fits into 2176 2 times, leaving a remainder of 538.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1638 from 2176 and we're left with 538.
Grab the next digit (3) from the dividend, add it to 538, then carry on: 5383 / 819

Advancing to step 5:
If we divide 5383 by 819, we get 6 and a remainder of 469.
The next digit of our result is 6. 
Result so far: 26.0
Subtracting 4914 from 5383 leaves us with 469.
Grab the next digit (8) from the dividend, add it to 469, then carry on: 4698 / 819

Moving on to step 6:
The number 819 fits into 4698 5 times, leaving a remainder of 603.
Put 5 as the next digit of the answer. 
Result so far: 265.0
Subtract 4095 from 4698 to get 603.
Include the next digit (8) from the dividend after 603, then repeat: 6038 / 819

Let's proceed to step 7:
819 goes into 6038 7 times with a remainder of 305.
The next digit of our result is 7. 
Result so far: 2657.0
If we subtract 5733 from 6038, we get 305.
Include the next digit (9) from the dividend after 305, then repeat: 3059 / 819

Step 8:
3059 divided by 819 is 3 with a remainder of 602.
Record the quotient 3 as the next digit in the result. 
Result so far: 26573.0
Subtract 2457 from 3059 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Let's proceed to step 9:
6020 divided by 819 is 7 with a remainder of 287.
Put 7 as the next digit of the answer. 
Result so far: 26573.7
The remainder is 287 after subtracting 5733 from 6020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Step 10:
The number 819 fits into 2870 3 times, leaving a remainder of 413.
The next digit of our result is 3. 
Result so far: 26573.73
If we take 2457 away from 2870, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Let's proceed to step 11:
The number 819 fits into 4130 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 26573.735
If we subtract 4095 from 4130, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
When dividing 350 by 819, we get 0 with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 26573.735
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 13:
819 goes into 3500 4 times with a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 26573.73504
Subtracting 3276 from 3500 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
The number 819 fits into 2240 2 times, leaving a remainder of 602.
Record the quotient 2 as the next digit in the result. 
Result so far: 26573.735042
Subtract 1638 from 2240 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Going ahead to step 15:
When dividing 6020 by 819, we get 7 with a remainder of 287.
The next digit of our result is 7. 
Result so far: 26573.7350427
Deduct 5733 from 6020 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 16:
2870 divided by 819 is 3 with a remainder of 413.
Write down 3 as next digit of the result. 
Result so far: 26573.73504273
Subtract 2457 from 2870 to get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

After the division, we end up with 26573.73504273 and a remainder of 4.13e-07.
