854634 ÷ 15 
We want to figure out the number of times 854634 can be divided by 15.

Step 1:
When dividing 8 by 15, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 15

On to step 2:
When dividing 85 by 15, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 75 from 85, we get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 15

Going ahead to step 3:
104 divided by 15 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 90 from 104, we get 14.
Fetch the next digit (6) from the dividend, attach it to 14 and continue: 146 / 15

Advancing to step 4:
146 divided by 15 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 569.0
The remainder is 11 after subtracting 135 from 146.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 15

Moving on to step 5:
15 can be fit into 113 7 times, resulting in a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 5697.0
Deduct 105 from 113 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 15

On to step 6:
15 can be fit into 84 5 times, resulting in a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 56975.0
If we take 75 away from 84, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 15, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 56975.6
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 56975.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 56975.6
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 56975.6 and a remainder of 0.0.
