We look at the division of 389461 by 51 
Let's see how many times 51 fits into 389461.

Step 1:
The number 51 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 51

Moving on to step 2:
38 divided by 51 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 51

Let's proceed to step 3:
389 divided by 51 is 7 with a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 32 after subtracting 357 from 389.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 51

Moving on to step 4:
324 divided by 51 is 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 76.0
If we take 306 away from 324, we end up with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 51

Advancing to step 5:
If we divide 186 by 51, we get 3 and a remainder of 33.
The next digit of our result is 3. 
Result so far: 763.0
Subtract 153 from 186 to get 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 51

Moving on to step 6:
51 can be fit into 331 6 times, resulting in a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 7636.0
The remainder is 25 after subtracting 306 from 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
If we divide 250 by 51, we get 4 and a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 7636.4
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
The number 51 fits into 460 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 7636.49
If we subtract 459 from 460, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
When dividing 10 by 51, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7636.49
If we subtract 0 from 10, we 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.

Step 10:
100 divided by 51 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 7636.4901
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 11:
When dividing 490 by 51, we get 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 7636.49019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
When dividing 310 by 51, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 7636.490196
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.

Let's proceed to step 13:
When dividing 40 by 51, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7636.490196
Subtract 0 from 40 to 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.

Step 14:
400 divided by 51 is 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 7636.49019607
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.

The final result is 7636.49019607 with a remainder of 4.3e-08.
