We're dividing 23778647 by 821 
Our goal is to divide 23778647 by 821.

Going ahead to step 1:
The number 821 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 821

Moving on to step 2:
If we divide 23 by 821, we get 0 and a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Take the next digit (7) from the dividend and append it to 23, then repeat: 237 / 821

Moving on to step 3:
When dividing 237 by 821, we get 0 with a remainder of 237.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 237 and we're left with 237.
Append the next digit (7) from the dividend to 237 and continue with: 2377 / 821

Advancing to step 4:
If we divide 2377 by 821, we get 2 and a remainder of 735.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1642 from 2377, we get 735.
Include the next digit (8) from the dividend after 735, then repeat: 7358 / 821

On to step 5:
If we divide 7358 by 821, we get 8 and a remainder of 790.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 6568 from 7358 to get 790.
Bring next digit (6) of the dividend behind the 790 and repeat the process: 7906 / 821

Let's proceed to step 6:
821 goes into 7906 9 times with a remainder of 517.
Use 9 as the next digit of our solution. 
Result so far: 289.0
Deduct 7389 from 7906 and we're left with 517.
Bring next digit (4) of the dividend behind the 517 and repeat the process: 5174 / 821

Step 7:
821 goes into 5174 6 times with a remainder of 248.
Put 6 as the next digit of the answer. 
Result so far: 2896.0
Subtract 4926 from 5174 to get 248.
Grab the next digit (7) from the dividend, add it to 248, then carry on: 2487 / 821

Advancing to step 8:
821 goes into 2487 3 times with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 28963.0
If we take 2463 away from 2487, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
When dividing 240 by 821, we get 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 28963.0
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 10:
When dividing 2400 by 821, we get 2 with a remainder of 758.
Put 2 as the next digit of the answer. 
Result so far: 28963.02
Deduct 1642 from 2400 and we're left with 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

On to step 11:
If we divide 7580 by 821, we get 9 and a remainder of 191.
Write down 9 as next digit of the result. 
Result so far: 28963.029
The remainder is 191 after subtracting 7389 from 7580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Step 12:
1910 divided by 821 is 2 with a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 28963.0292
If we subtract 1642 from 1910, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 13:
2680 divided by 821 is 3 with a remainder of 217.
Record the quotient 3 as the next digit in the result. 
Result so far: 28963.02923
The remainder is 217 after subtracting 2463 from 2680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Let's proceed to step 14:
2170 divided by 821 is 2 with a remainder of 528.
Record the quotient 2 as the next digit in the result. 
Result so far: 28963.029232
If we subtract 1642 from 2170, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 15:
If we divide 5280 by 821, we get 6 and a remainder of 354.
The number 6 becomes the next digit in our result. 
Result so far: 28963.0292326
If we take 4926 away from 5280, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

On to step 16:
When dividing 3540 by 821, we get 4 with a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 28963.02923264
If we subtract 3284 from 3540, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 28963.02923264 and a remainder of 2.56e-07.
