478397 divided by 51 
Let's see how many times 51 fits into 478397.

Going ahead to step 1:
When dividing 4 by 51, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 51

Advancing to step 2:
47 divided by 51 is 0 with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Grab the next digit (8) from the dividend, add it to 47, then carry on: 478 / 51

Advancing to step 3:
When dividing 478 by 51, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 459 from 478 and we're left with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 51

Let's proceed to step 4:
The number 51 fits into 193 3 times, leaving a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we subtract 153 from 193, we get 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 51

Moving on to step 5:
When dividing 409 by 51, we get 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 938.0
If we take 408 away from 409, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 51

Let's proceed to step 6:
17 divided by 51 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 9380.0
The remainder is 17 after subtracting 0 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
51 can be fit into 170 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 9380.3
Subtracting 153 from 170 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
If we divide 170 by 51, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 9380.33
The remainder is 17 after subtracting 153 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 9380.33, with a leftover of 0.017.
