We look at the division of 387720 by 51 
Our goal is to divide 387720 by 51.

Moving on to step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 51

Let's proceed to step 2:
38 divided by 51 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 51

On to step 3:
51 goes into 387 7 times with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 357 from 387 and we're left with 30.
Take the next digit (7) from the dividend and append it to 30, then repeat: 307 / 51

Step 4:
51 goes into 307 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
Subtract 306 from 307 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 51

Let's proceed to step 5:
When dividing 12 by 51, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 760.0
If we take 0 away from 12, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 51

Advancing to step 6:
120 divided by 51 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 7602.0
If we subtract 102 from 120, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 51, we get 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 7602.3
Deduct 153 from 180 and we're left 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.

On to step 8:
If we divide 270 by 51, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7602.35
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
150 divided by 51 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 7602.352
If we take 102 away from 150, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
480 divided by 51 is 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 7602.3529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 7602.35294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
When dividing 60 by 51, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 7602.352941
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.

Moving on to step 13:
When dividing 90 by 51, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 7602.3529411
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 7602.3529411 and a remainder of 3.9e-07.
