We're dividing 621444 by 51 
We want to divide 621444 by 51.

Let's proceed to step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 51

Going ahead to step 2:
When dividing 62 by 51, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 11 after subtracting 51 from 62.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 51

Let's proceed to step 3:
111 divided by 51 is 2 with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 102 from 111 leaves us with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 51

Going ahead to step 4:
51 goes into 94 1 times with a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 51 from 94 to get 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 51

Step 5:
If we divide 434 by 51, we get 8 and a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 1218.0
If we subtract 408 from 434, we get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 51

Step 6:
264 divided by 51 is 5 with a remainder of 9.
The next digit of our result is 5. 
Result so far: 12185.0
The remainder is 9 after subtracting 255 from 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
When dividing 90 by 51, we get 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 12185.1
If we take 51 away from 90, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
390 divided by 51 is 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 12185.17
If we take 357 away from 390, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
51 can be fit into 330 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 12185.176
If we take 306 away from 330, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
51 can be fit into 240 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 12185.1764
Subtract 204 from 240 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
51 can be fit into 360 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 12185.17647
The remainder is 3 after subtracting 357 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
51 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 12185.17647
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
51 goes into 300 5 times with a remainder of 45.
The next digit of our result is 5. 
Result so far: 12185.1764705
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 12185.17647058
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 12185.17647058 with a balance of 4.2e-08.
