We look at the division of 361766 by 87 
Let's see how many times 87 fits into 361766.

Let's proceed to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 87

Advancing to step 2:
87 goes into 36 0 times with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 87

Moving on to step 3:
87 goes into 361 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 348 from 361 leaves us with 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 87

On to step 4:
The number 87 fits into 137 1 times, leaving a remainder of 50.
The next digit of our result is 1. 
Result so far: 41.0
Subtract 87 from 137 to get 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 87

On to step 5:
If we divide 506 by 87, we get 5 and a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 415.0
Subtracting 435 from 506 leaves us with 71.
Include the next digit (6) from the dividend after 71, then repeat: 716 / 87

Let's proceed to step 6:
The number 87 fits into 716 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 4158.0
Subtract 696 from 716 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
87 can be fit into 200 2 times, resulting in a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 4158.2
If we subtract 174 from 200, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
87 can be fit into 260 2 times, resulting in a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 4158.22
Subtracting 174 from 260 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Our division results in 4158.22 with a remaining 0.086.
