We divide 20566138 by 51
Our goal is to divide 20566138 by 51.

Advancing to step 1:
If we divide 2 by 51, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 51

Step 2:
20 divided by 51 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 51

On to step 3:
205 divided by 51 is 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 204 away from 205, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 51

Moving on to step 4:
If we divide 16 by 51, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 51

Step 5:
166 divided by 51 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 403.0
If we take 153 away from 166, we end up with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 51

Moving on to step 6:
If we divide 131 by 51, we get 2 and a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 4032.0
If we take 102 away from 131, we end up with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 51

On to step 7:
The number 51 fits into 293 5 times, leaving a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 40325.0
If we subtract 255 from 293, we get 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 51

Moving on to step 8:
When dividing 388 by 51, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 403257.0
If we subtract 357 from 388, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 9:
310 divided by 51 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 403257.6
Deduct 306 from 310 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 51, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 403257.6
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
51 goes into 400 7 times with a remainder of 43.
The next digit of our result is 7. 
Result so far: 403257.607
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
51 can be fit into 430 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 403257.6078
Subtracting 408 from 430 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
51 can be fit into 220 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 403257.60784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
160 divided by 51 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 403257.607843
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 15:
51 can be fit into 70 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 403257.6078431
If we subtract 51 from 70, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 16:
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: 403257.60784313
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 403257.60784313 with a remainder of 3.7e-08.
