We're dividing 20866096 by 51 
Our goal is to divide 20866096 by 51.

Let's proceed to step 1:
The number 51 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 51

Step 2:
When dividing 20 by 51, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 51

Advancing to step 3:
If we divide 208 by 51, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 204 away from 208, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 51

Step 4:
The number 51 fits into 46 0 times, leaving a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we subtract 0 from 46, we get 46.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 51

Going ahead to step 5:
51 can be fit into 466 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 409.0
Subtract 459 from 466 to get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 51

Going ahead to step 6:
70 divided by 51 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 4091.0
Deduct 51 from 70 and we're left with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 51

Going ahead to step 7:
51 can be fit into 199 3 times, resulting in a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 40913.0
If we take 153 away from 199, we end up with 46.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 51

Step 8:
51 goes into 466 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 409139.0
If we subtract 459 from 466, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
70 divided by 51 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 409139.1
If we take 51 away from 70, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
51 can be fit into 190 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 409139.13
Subtract 153 from 190 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
The number 51 fits into 370 7 times, leaving a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 409139.137
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 12:
If we divide 130 by 51, we get 2 and a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 409139.1372
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
If we divide 280 by 51, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 409139.13725
If we take 255 away from 280, 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.

Moving on to step 14:
51 goes into 250 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 409139.137254
Deduct 204 from 250 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.

Let's proceed to step 15:
The number 51 fits into 460 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 409139.1372549
Subtracting 459 from 460 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 16:
If we divide 10 by 51, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 409139.1372549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 409139.1372549 with a balance of 1e-08.
