We look at the division of 866532 by 53 
We want to figure out the number of times 866532 can be divided by 53.

On to step 1:
The number 53 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 53

Let's proceed to step 2:
When dividing 86 by 53, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 33 after subtracting 53 from 86.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 53

Let's proceed to step 3:
53 can be fit into 336 6 times, resulting in a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 318 from 336 to get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 53

Step 4:
If we divide 185 by 53, we get 3 and a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
Deduct 159 from 185 and we're left with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 53

Let's proceed to step 5:
If we divide 263 by 53, we get 4 and a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 1634.0
Subtract 212 from 263 to get 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 53

On to step 6:
53 can be fit into 512 9 times, resulting in a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 16349.0
If we take 477 away from 512, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
When dividing 350 by 53, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 16349.6
Subtract 318 from 350 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
320 divided by 53 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 16349.66
Subtracting 318 from 320 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 16349.66, and the remainder is 0.002.
