We're dividing 854634 by 10 
Our goal is to divide 854634 by 10.

Advancing to step 1:
If we divide 8 by 10, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 10

Advancing to step 2:
The number 10 fits into 85 8 times, leaving a remainder of 5.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 5 after subtracting 80 from 85.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 10

Advancing to step 3:
54 divided by 10 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtracting 50 from 54 leaves us with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 10

Going ahead to step 4:
When dividing 46 by 10, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 854.0
Subtracting 40 from 46 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 10

On to step 5:
10 goes into 63 6 times with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 8546.0
Subtract 60 from 63 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 10

Advancing to step 6:
10 goes into 34 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 85463.0
Subtracting 30 from 34 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 10 fits into 40 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 85463.4
Deduct 40 from 40 and we're left 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.

Advancing to step 8:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 85463.4
Deduct 0 from 0 and we're left 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.

On to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 85463.4
If we take 0 away from 0, we end up 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.

The final outcome is 85463.4, with a leftover of 0.0.
