407666 ÷ 87 
We want to figure out the number of times 407666 can be divided by 87.

Going ahead to step 1:
The number 87 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 87

Let's proceed to step 2:
40 divided by 87 is 0 with 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.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 87

On to step 3:
407 divided by 87 is 4 with a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 348 away from 407, we end up with 59.
Include the next digit (6) from the dividend after 59, then repeat: 596 / 87

Going ahead to step 4:
87 can be fit into 596 6 times, resulting in a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we take 522 away from 596, we end up with 74.
Take the next digit (6) from the dividend and append it to 74, then repeat: 746 / 87

Let's proceed to step 5:
746 divided by 87 is 8 with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 468.0
The remainder is 50 after subtracting 696 from 746.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 87

Let's proceed to step 6:
506 divided by 87 is 5 with a remainder of 71.
The number 5 becomes the next digit in our result. 
Result so far: 4685.0
Subtracting 435 from 506 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 7:
If we divide 710 by 87, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 4685.8
Deduct 696 from 710 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
140 divided by 87 is 1 with a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 4685.81
Subtracting 87 from 140 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
If we divide 530 by 87, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 4685.816
If we subtract 522 from 530, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
87 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4685.816
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
87 can be fit into 800 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 4685.81609
The remainder is 17 after subtracting 783 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
87 goes into 170 1 times with a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 4685.816091
The remainder is 83 after subtracting 87 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 13:
The number 87 fits into 830 9 times, leaving a remainder of 47.
The next digit of our result is 9. 
Result so far: 4685.8160919
Subtract 783 from 830 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 14:
87 goes into 470 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4685.81609195
Subtracting 435 from 470 leaves us 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.

After the division, we end up with 4685.81609195 and a remainder of 3.5e-08.
