We divide 800354 by 15
We want to divide 800354 by 15.

Going ahead to step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 15

Going ahead to step 2:
When dividing 80 by 15, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 75 from 80, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 15

Going ahead to step 3:
15 goes into 50 3 times with a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 53.0
If we subtract 45 from 50, we get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 15

Advancing to step 4:
15 can be fit into 53 3 times, resulting in a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 533.0
The remainder is 8 after subtracting 45 from 53.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 15

Going ahead to step 5:
85 divided by 15 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 5335.0
Deduct 75 from 85 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 15

Let's proceed to step 6:
104 divided by 15 is 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 53356.0
Deduct 90 from 104 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
140 divided by 15 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 53356.9
Subtracting 135 from 140 leaves us 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 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 53356.93
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.

Let's proceed to step 9:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 53356.933
If we take 45 away from 50, we end up 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.

After the division, we end up with 53356.933 and a remainder of 0.0005.
