We're dividing 618240 by 51 
Our goal is to divide 618240 by 51.

Advancing to step 1:
If we divide 6 by 51, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 51

Moving on to step 2:
The number 51 fits into 61 1 times, leaving a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 51 away from 61, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 51

Advancing to step 3:
The number 51 fits into 108 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 102 away from 108, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 51

Going ahead to step 4:
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: 121.0
If we take 51 away from 62, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 51

Moving on to step 5:
51 can be fit into 114 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 1212.0
The remainder is 12 after subtracting 102 from 114.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 51

Advancing to step 6:
The number 51 fits into 120 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12122.0
If we take 102 away from 120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
51 can be fit into 180 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 12122.3
Subtracting 153 from 180 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 8:
270 divided by 51 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 12122.35
If we take 255 away from 270, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
When dividing 150 by 51, we get 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 12122.352
Subtract 102 from 150 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
51 goes into 480 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 12122.3529
If we subtract 459 from 480, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
51 can be fit into 210 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 12122.35294
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
If we divide 60 by 51, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 12122.352941
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
51 goes into 90 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 12122.3529411
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 12122.3529411 with a balance of 3.9e-07.
