We look at the division of 405162 by 87 
Our goal is to divide 405162 by 87.

On to step 1:
When dividing 4 by 87, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 87

Advancing to step 2:
The number 87 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 87

Advancing to step 3:
87 can be fit into 405 4 times, resulting in a remainder of 57.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 348 from 405 and we're left with 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 87

Going ahead to step 4:
If we divide 571 by 87, we get 6 and a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 522 away from 571, we end up with 49.
Bring next digit (6) of the dividend behind the 49 and repeat the process: 496 / 87

Moving on to step 5:
87 goes into 496 5 times with a remainder of 61.
Put 5 as the next digit of the answer. 
Result so far: 465.0
The remainder is 61 after subtracting 435 from 496.
Take the next digit (2) from the dividend and append it to 61, then repeat: 612 / 87

On to step 6:
The number 87 fits into 612 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 4657.0
Subtracting 609 from 612 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
87 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 4657.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
87 goes into 300 3 times with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 4657.03
If we subtract 261 from 300, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
87 can be fit into 390 4 times, resulting in a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 4657.034
The remainder is 42 after subtracting 348 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
When dividing 420 by 87, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 4657.0344
If we subtract 348 from 420, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 4657.0344 with a remaining 0.00072.
