We look at the division of 386320 by 51 
Our goal is to divide 386320 by 51.

Let's proceed to step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 51

Advancing to step 2:
When dividing 38 by 51, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 51

Step 3:
When dividing 386 by 51, we get 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 29 after subtracting 357 from 386.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 51

Going ahead to step 4:
51 can be fit into 293 5 times, resulting in a remainder of 38.
The next digit of our result is 5. 
Result so far: 75.0
Subtracting 255 from 293 leaves us with 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 51

Advancing to step 5:
51 goes into 382 7 times with a remainder of 25.
The next digit of our result is 7. 
Result so far: 757.0
Subtract 357 from 382 to get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 51

Moving on to step 6:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 7574.0
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.

Going ahead to step 7:
51 goes into 460 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7574.9
The remainder is 1 after subtracting 459 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
51 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 7574.9
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
51 can be fit into 100 1 times, resulting in a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 7574.901
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 10:
490 divided by 51 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 7574.9019
The remainder is 31 after subtracting 459 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
The number 51 fits into 310 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 7574.90196
Subtracting 306 from 310 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
51 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 7574.90196
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 7574.9019607
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 14:
The number 51 fits into 430 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 7574.90196078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 7574.90196078 with a balance of 2.2e-08.
