Let's divide 666186 by 87
Our goal is to divide 666186 by 87.

On to step 1:
The number 87 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 87

Advancing to step 2:
When dividing 66 by 87, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 87

Step 3:
87 can be fit into 666 7 times, resulting in a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 609 from 666 leaves us with 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 87

Step 4:
If we divide 571 by 87, we get 6 and a remainder of 49.
Use 6 as the next digit of our solution. 
Result so far: 76.0
The remainder is 49 after subtracting 522 from 571.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 87

Going ahead to step 5:
87 can be fit into 498 5 times, resulting in a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 765.0
If we subtract 435 from 498, we get 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 87

Moving on to step 6:
87 can be fit into 636 7 times, resulting in a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 7657.0
Subtract 609 from 636 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
If we divide 270 by 87, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 7657.3
If we subtract 261 from 270, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
87 goes into 90 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 7657.31
Deduct 87 from 90 and we're left 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.

On to step 9:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 7657.31
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
The number 87 fits into 300 3 times, leaving a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 7657.3103
Subtracting 261 from 300 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 11:
87 goes into 390 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 7657.31034
If we subtract 348 from 390, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
87 goes into 420 4 times with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 7657.310344
Deduct 348 from 420 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 7657.310344, and the remainder is 7.2e-06.
