We're dividing 620366 by 51 
We want to divide 620366 by 51.

On to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 51

Step 2:
The number 51 fits into 62 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 51 away from 62, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 51

Going ahead to step 3:
51 goes into 110 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 102 from 110, we get 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 51

Let's proceed to step 4:
51 can be fit into 83 1 times, resulting in a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtracting 51 from 83 leaves us with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 51

Let's proceed to step 5:
51 can be fit into 326 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 1216.0
The remainder is 20 after subtracting 306 from 326.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 51

On to step 6:
206 divided by 51 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 12164.0
Deduct 204 from 206 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
51 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 12164.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
51 can be fit into 200 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 12164.03
Subtracting 153 from 200 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
470 divided by 51 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 12164.039
If we subtract 459 from 470, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
When dividing 110 by 51, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 12164.0392
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
51 goes into 80 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 12164.03921
Subtracting 51 from 80 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
51 goes into 290 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 12164.039215
Subtract 255 from 290 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
51 can be fit into 350 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 12164.0392156
Subtracting 306 from 350 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
The number 51 fits into 440 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 12164.03921568
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 12164.03921568 and a remainder of 3.2e-08.
