We look at the division of 855758 by 15 
Our goal is to divide 855758 by 15.

Advancing to step 1:
When dividing 8 by 15, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 15

Advancing to step 2:
If we divide 85 by 15, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 10 after subtracting 75 from 85.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 15

Step 3:
105 divided by 15 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we take 105 away from 105, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 15

Step 4:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 570.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 15

Advancing to step 5:
If we divide 75 by 15, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5705.0
If we subtract 75 from 75, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 15

Step 6:
If we divide 8 by 15, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 57050.0
Subtract 0 from 8 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
15 can be fit into 80 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 57050.5
If we subtract 75 from 80, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 57050.53
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 15 is 3 with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 57050.533
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 57050.533, with a leftover of 0.0005.
