We're dividing 854643 by 53 
We want to divide 854643 by 53.

Moving on to step 1:
If we divide 8 by 53, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 53

Going ahead to step 2:
The number 53 fits into 85 1 times, leaving a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 53 from 85 and we're left with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 53

Let's proceed to step 3:
If we divide 324 by 53, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 318 from 324, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 53

Moving on to step 4:
If we divide 66 by 53, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
Subtract 53 from 66 to get 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 53

Advancing to step 5:
The number 53 fits into 134 2 times, leaving a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 1612.0
The remainder is 28 after subtracting 106 from 134.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 53

Step 6:
If we divide 283 by 53, we get 5 and a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 16125.0
If we subtract 265 from 283, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
The number 53 fits into 180 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 16125.3
Deduct 159 from 180 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
53 goes into 210 3 times with a remainder of 51.
The next digit of our result is 3. 
Result so far: 16125.33
If we take 159 away from 210, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The quotient of the division is 16125.33, and the remainder is 0.051.
