20835377 ÷ 821 
We want to figure out the number of times 20835377 can be divided by 821.

Going ahead to step 1:
821 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 821

Advancing to step 2:
When dividing 20 by 821, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 821

On to step 3:
If we divide 208 by 821, we get 0 and a remainder of 208.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 208 leaves us with 208.
Grab the next digit (3) from the dividend, add it to 208, then carry on: 2083 / 821

Advancing to step 4:
821 goes into 2083 2 times with a remainder of 441.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1642 from 2083 to get 441.
Include the next digit (5) from the dividend after 441, then repeat: 4415 / 821

Advancing to step 5:
821 can be fit into 4415 5 times, resulting in a remainder of 310.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 4105 from 4415 and we're left with 310.
Grab the next digit (3) from the dividend, add it to 310, then carry on: 3103 / 821

On to step 6:
821 can be fit into 3103 3 times, resulting in a remainder of 640.
Record the quotient 3 as the next digit in the result. 
Result so far: 253.0
Subtracting 2463 from 3103 leaves us with 640.
Fetch the next digit (7) from the dividend, attach it to 640 and continue: 6407 / 821

Moving on to step 7:
If we divide 6407 by 821, we get 7 and a remainder of 660.
Write down 7 as next digit of the result. 
Result so far: 2537.0
Subtracting 5747 from 6407 leaves us with 660.
Take the next digit (7) from the dividend and append it to 660, then repeat: 6607 / 821

Step 8:
6607 divided by 821 is 8 with a remainder of 39.
The next digit of our result is 8. 
Result so far: 25378.0
Subtract 6568 from 6607 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
If we divide 390 by 821, we get 0 and a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 25378.0
The remainder is 390 after subtracting 0 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 10:
The number 821 fits into 3900 4 times, leaving a remainder of 616.
The number 4 becomes the next digit in our result. 
Result so far: 25378.04
Deduct 3284 from 3900 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 11:
When dividing 6160 by 821, we get 7 with a remainder of 413.
The next digit of our result is 7. 
Result so far: 25378.047
Subtract 5747 from 6160 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.

Step 12:
If we divide 4130 by 821, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 25378.0475
If we take 4105 away from 4130, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 13:
250 divided by 821 is 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 25378.0475
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 14:
When dividing 2500 by 821, we get 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 25378.047503
The remainder is 37 after subtracting 2463 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 15:
When dividing 370 by 821, we get 0 with a remainder of 370.
Use 0 as the next digit of our solution. 
Result so far: 25378.047503
If we take 0 away from 370, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 16:
821 goes into 3700 4 times with a remainder of 416.
Use 4 as the next digit of our solution. 
Result so far: 25378.04750304
Subtracting 3284 from 3700 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Our division results in 25378.04750304 with a remaining 4.16e-07.
