We look at the division of 20857985 by 764 
We want to figure out the number of times 20857985 can be divided by 764.

Let's proceed to step 1:
2 divided by 764 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 764

Advancing to step 2:
764 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 764

Step 3:
If we divide 208 by 764, we get 0 and a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 208 leaves us with 208.
Bring next digit (5) of the dividend behind the 208 and repeat the process: 2085 / 764

Going ahead to step 4:
2085 divided by 764 is 2 with a remainder of 557.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1528 away from 2085, we end up with 557.
Include the next digit (7) from the dividend after 557, then repeat: 5577 / 764

Step 5:
If we divide 5577 by 764, we get 7 and a remainder of 229.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 5348 from 5577 to get 229.
Grab the next digit (9) from the dividend, add it to 229, then carry on: 2299 / 764

Moving on to step 6:
If we divide 2299 by 764, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 273.0
If we take 2292 away from 2299, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 764

Let's proceed to step 7:
The number 764 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 2730.0
Subtracting 0 from 78 leaves us with 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 764

Advancing to step 8:
785 divided by 764 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 27301.0
If we subtract 764 from 785, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
210 divided by 764 is 0 with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 27301.0
Subtracting 0 from 210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
When dividing 2100 by 764, we get 2 with a remainder of 572.
Write down 2 as next digit of the result. 
Result so far: 27301.02
If we take 1528 away from 2100, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 11:
When dividing 5720 by 764, we get 7 with a remainder of 372.
Put 7 as the next digit of the answer. 
Result so far: 27301.027
Deduct 5348 from 5720 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 12:
When dividing 3720 by 764, we get 4 with a remainder of 664.
The next digit of our result is 4. 
Result so far: 27301.0274
The remainder is 664 after subtracting 3056 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Let's proceed to step 13:
When dividing 6640 by 764, we get 8 with a remainder of 528.
Record the quotient 8 as the next digit in the result. 
Result so far: 27301.02748
The remainder is 528 after subtracting 6112 from 6640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 14:
5280 divided by 764 is 6 with a remainder of 696.
Put 6 as the next digit of the answer. 
Result so far: 27301.027486
Subtracting 4584 from 5280 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Let's proceed to step 15:
When dividing 6960 by 764, we get 9 with a remainder of 84.
The next digit of our result is 9. 
Result so far: 27301.0274869
Deduct 6876 from 6960 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 16:
The number 764 fits into 840 1 times, leaving a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 27301.02748691
Deduct 764 from 840 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 27301.02748691 with a remainder of 7.6e-08.
