20909730 ÷ 523 
We want to divide 20909730 by 523.

Going ahead to step 1:
523 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.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 523

Going ahead to step 2:
523 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 523

Step 3:
523 goes into 209 0 times with a remainder of 209.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 209, we get 209.
Append the next digit (0) from the dividend to 209 and continue with: 2090 / 523

Advancing to step 4:
2090 divided by 523 is 3 with a remainder of 521.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 1569 from 2090 leaves us with 521.
Take the next digit (9) from the dividend and append it to 521, then repeat: 5219 / 523

Let's proceed to step 5:
The number 523 fits into 5219 9 times, leaving a remainder of 512.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtracting 4707 from 5219 leaves us with 512.
Take the next digit (7) from the dividend and append it to 512, then repeat: 5127 / 523

On to step 6:
When dividing 5127 by 523, we get 9 with a remainder of 420.
The number 9 becomes the next digit in our result. 
Result so far: 399.0
Deduct 4707 from 5127 and we're left with 420.
Take the next digit (3) from the dividend and append it to 420, then repeat: 4203 / 523

Let's proceed to step 7:
When dividing 4203 by 523, we get 8 with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 3998.0
Deduct 4184 from 4203 and we're left with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 523

Moving on to step 8:
When dividing 190 by 523, we get 0 with a remainder of 190.
The next digit of our result is 0. 
Result so far: 39980.0
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 9:
1900 divided by 523 is 3 with a remainder of 331.
Write down 3 as next digit of the result. 
Result so far: 39980.3
The remainder is 331 after subtracting 1569 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 10:
523 can be fit into 3310 6 times, resulting in a remainder of 172.
Write down 6 as next digit of the result. 
Result so far: 39980.36
The remainder is 172 after subtracting 3138 from 3310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 11:
The number 523 fits into 1720 3 times, leaving a remainder of 151.
Use 3 as the next digit of our solution. 
Result so far: 39980.363
The remainder is 151 after subtracting 1569 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 12:
When dividing 1510 by 523, we get 2 with a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 39980.3632
Deduct 1046 from 1510 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 13:
If we divide 4640 by 523, we get 8 and a remainder of 456.
Record the quotient 8 as the next digit in the result. 
Result so far: 39980.36328
If we take 4184 away from 4640, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Let's proceed to step 14:
If we divide 4560 by 523, we get 8 and a remainder of 376.
Use 8 as the next digit of our solution. 
Result so far: 39980.363288
Subtracting 4184 from 4560 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The quotient of the division is 39980.363288, and the remainder is 3.76e-05.
