We divide 479689 by 51
We want to figure out the number of times 479689 can be divided by 51.

Step 1:
When dividing 4 by 51, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
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

Moving on to step 2:
When dividing 47 by 51, we get 0 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.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 51

Advancing to step 3:
479 divided by 51 is 9 with a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 459 from 479 to get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 51

Going ahead to step 4:
If we divide 206 by 51, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 94.0
If we subtract 204 from 206, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 51

Moving on to step 5:
The number 51 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 940.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 51

Going ahead to step 6:
The number 51 fits into 289 5 times, leaving a remainder of 34.
The next digit of our result is 5. 
Result so far: 9405.0
If we take 255 away from 289, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
When dividing 340 by 51, we get 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 9405.6
If we subtract 306 from 340, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
When dividing 340 by 51, we get 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 9405.66
Subtract 306 from 340 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 9405.66, with a leftover of 0.034.
