Let's divide 479389 by 51
We want to divide 479389 by 51.

Going ahead to step 1:
4 divided by 51 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 51

Going ahead to step 2:
51 goes into 47 0 times with a remainder of 47.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 51

Advancing to step 3:
479 divided by 51 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 459 from 479 leaves us with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 51

Let's proceed to step 4:
When dividing 203 by 51, we get 3 with a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Subtracting 153 from 203 leaves us with 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 51

On to step 5:
If we divide 508 by 51, we get 9 and a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 939.0
If we take 459 away from 508, we end up with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 51

On to step 6:
51 can be fit into 499 9 times, resulting in a remainder of 40.
The next digit of our result is 9. 
Result so far: 9399.0
Deduct 459 from 499 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
When dividing 400 by 51, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 9399.7
If we subtract 357 from 400, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 8:
430 divided by 51 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 9399.78
Subtracting 408 from 430 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
When dividing 220 by 51, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 9399.784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 51 fits into 160 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 9399.7843
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
When dividing 70 by 51, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 9399.78431
Subtracting 51 from 70 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 12:
51 goes into 190 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 9399.784313
Subtracting 153 from 190 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
51 can be fit into 370 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 9399.7843137
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
51 can be fit into 130 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 9399.78431372
Subtracting 102 from 130 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 9399.78431372 with a remaining 2.8e-08.
