Let's divide 20530627 by 51
We want to figure out the number of times 20530627 can be divided by 51.

On to step 1:
If we divide 2 by 51, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 51

Step 2:
51 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of 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 / 51

Step 3:
When dividing 205 by 51, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 1 after subtracting 204 from 205.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 51

On to step 4:
13 divided by 51 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 40.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 51

Going ahead to step 5:
If we divide 130 by 51, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
If we subtract 102 from 130, we get 28.
Bring next digit (6) of the dividend behind the 28 and repeat the process: 286 / 51

Going ahead to step 6:
286 divided by 51 is 5 with a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 4025.0
Subtracting 255 from 286 leaves us with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 51

Advancing to step 7:
51 goes into 312 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 40256.0
Subtracting 306 from 312 leaves us with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 51

Advancing to step 8:
67 divided by 51 is 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 402561.0
If we take 51 away from 67, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 402561.3
Subtracting 153 from 160 leaves us 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.

Advancing to step 10:
70 divided by 51 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 402561.31
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.

Step 11:
When dividing 190 by 51, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 402561.313
If we subtract 153 from 190, we 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.

Going ahead to step 12:
51 goes into 370 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 402561.3137
Deduct 357 from 370 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 13:
When dividing 130 by 51, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 402561.31372
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.

Going ahead to step 14:
51 goes into 280 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 402561.313725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 15:
If we divide 250 by 51, we get 4 and a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 402561.3137254
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.

Moving on to step 16:
When dividing 460 by 51, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 402561.31372549
Deduct 459 from 460 and we're left 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.

After the division, we end up with 402561.31372549 and a remainder of 1e-09.
