Let's divide 20835843 by 523
Our goal is to divide 20835843 by 523.

Advancing to step 1:
If we divide 2 by 523, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 523

On to step 2:
523 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 523

Moving on to step 3:
If we divide 208 by 523, we get 0 and a remainder of 208.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 208, we get 208.
Take the next digit (3) from the dividend and append it to 208, then repeat: 2083 / 523

Advancing to step 4:
523 goes into 2083 3 times with a remainder of 514.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1569 from 2083, we get 514.
Include the next digit (5) from the dividend after 514, then repeat: 5145 / 523

Let's proceed to step 5:
523 can be fit into 5145 9 times, resulting in a remainder of 438.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 4707 from 5145 leaves us with 438.
Append the next digit (8) from the dividend to 438 and continue with: 4388 / 523

Advancing to step 6:
When dividing 4388 by 523, we get 8 with a remainder of 204.
Write down 8 as next digit of the result. 
Result so far: 398.0
The remainder is 204 after subtracting 4184 from 4388.
Append the next digit (4) from the dividend to 204 and continue with: 2044 / 523

Step 7:
The number 523 fits into 2044 3 times, leaving a remainder of 475.
Record the quotient 3 as the next digit in the result. 
Result so far: 3983.0
Subtract 1569 from 2044 to get 475.
Append the next digit (3) from the dividend to 475 and continue with: 4753 / 523

Step 8:
When dividing 4753 by 523, we get 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 39839.0
Deduct 4707 from 4753 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
523 goes into 460 0 times with a remainder of 460.
Write down 0 as next digit of the result. 
Result so far: 39839.0
If we subtract 0 from 460, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 10:
The number 523 fits into 4600 8 times, leaving a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 39839.08
Subtracting 4184 from 4600 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.

Let's proceed to step 11:
523 can be fit into 4160 7 times, resulting in a remainder of 499.
Record the quotient 7 as the next digit in the result. 
Result so far: 39839.087
Subtracting 3661 from 4160 leaves us with 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Step 12:
The number 523 fits into 4990 9 times, leaving a remainder of 283.
Use 9 as the next digit of our solution. 
Result so far: 39839.0879
The remainder is 283 after subtracting 4707 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 13:
523 can be fit into 2830 5 times, resulting in a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 39839.08795
If we take 2615 away from 2830, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 14:
523 can be fit into 2150 4 times, resulting in a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 39839.087954
The remainder is 58 after subtracting 2092 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 15:
523 can be fit into 580 1 times, resulting in a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 39839.0879541
Deduct 523 from 580 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 16:
The number 523 fits into 570 1 times, leaving a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 39839.08795411
Subtract 523 from 570 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 39839.08795411 and a remainder of 4.7e-08.
