We look at the division of 20561582 by 766 
Our goal is to divide 20561582 by 766.

Advancing to step 1:
When dividing 2 by 766, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 766

Going ahead to step 2:
20 divided by 766 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 766

Let's proceed to step 3:
205 divided by 766 is 0 with a remainder of 205.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 205, we get 205.
Bring next digit (6) of the dividend behind the 205 and repeat the process: 2056 / 766

Step 4:
The number 766 fits into 2056 2 times, leaving a remainder of 524.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1532 away from 2056, we end up with 524.
Append the next digit (1) from the dividend to 524 and continue with: 5241 / 766

Moving on to step 5:
The number 766 fits into 5241 6 times, leaving a remainder of 645.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 645 after subtracting 4596 from 5241.
Include the next digit (5) from the dividend after 645, then repeat: 6455 / 766

Going ahead to step 6:
When dividing 6455 by 766, we get 8 with a remainder of 327.
Write down 8 as next digit of the result. 
Result so far: 268.0
The remainder is 327 after subtracting 6128 from 6455.
Fetch the next digit (8) from the dividend, attach it to 327 and continue: 3278 / 766

Let's proceed to step 7:
766 can be fit into 3278 4 times, resulting in a remainder of 214.
Use 4 as the next digit of our solution. 
Result so far: 2684.0
Subtracting 3064 from 3278 leaves us with 214.
Fetch the next digit (2) from the dividend, attach it to 214 and continue: 2142 / 766

On to step 8:
766 can be fit into 2142 2 times, resulting in a remainder of 610.
Put 2 as the next digit of the answer. 
Result so far: 26842.0
The remainder is 610 after subtracting 1532 from 2142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 9:
6100 divided by 766 is 7 with a remainder of 738.
Use 7 as the next digit of our solution. 
Result so far: 26842.7
The remainder is 738 after subtracting 5362 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

On to step 10:
766 goes into 7380 9 times with a remainder of 486.
Write down 9 as next digit of the result. 
Result so far: 26842.79
If we take 6894 away from 7380, we end up with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

On to step 11:
766 can be fit into 4860 6 times, resulting in a remainder of 264.
Write down 6 as next digit of the result. 
Result so far: 26842.796
Subtracting 4596 from 4860 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 12:
2640 divided by 766 is 3 with a remainder of 342.
The number 3 becomes the next digit in our result. 
Result so far: 26842.7963
Deduct 2298 from 2640 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 13:
3420 divided by 766 is 4 with a remainder of 356.
Write down 4 as next digit of the result. 
Result so far: 26842.79634
Deduct 3064 from 3420 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 14:
3560 divided by 766 is 4 with a remainder of 496.
Use 4 as the next digit of our solution. 
Result so far: 26842.796344
Subtracting 3064 from 3560 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

The final outcome is 26842.796344, with a leftover of 4.96e-05.
