401664 divided by 87 
Our goal is to divide 401664 by 87.

Going ahead to step 1:
When dividing 4 by 87, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 87

Let's proceed to step 2:
If we divide 40 by 87, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 87

Step 3:
The number 87 fits into 401 4 times, leaving a remainder of 53.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 348 from 401 leaves us with 53.
Fetch the next digit (6) from the dividend, attach it to 53 and continue: 536 / 87

Moving on to step 4:
When dividing 536 by 87, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Subtract 522 from 536 to get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 87

On to step 5:
If we divide 146 by 87, we get 1 and a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 461.0
If we subtract 87 from 146, we get 59.
Take the next digit (4) from the dividend and append it to 59, then repeat: 594 / 87

Going ahead to step 6:
594 divided by 87 is 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 4616.0
Subtract 522 from 594 to 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.

Moving on to step 7:
87 goes into 720 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 4616.8
The remainder is 24 after subtracting 696 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
The number 87 fits into 240 2 times, leaving a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 4616.82
Subtracting 174 from 240 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 9:
87 can be fit into 660 7 times, resulting in a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 4616.827
Subtract 609 from 660 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 10:
510 divided by 87 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 4616.8275
The remainder is 75 after subtracting 435 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 11:
750 divided by 87 is 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 4616.82758
If we take 696 away from 750, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
87 goes into 540 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 4616.827586
If we take 522 away from 540, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
When dividing 180 by 87, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 4616.8275862
Deduct 174 from 180 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 14:
87 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 4616.8275862
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 4616.8275862 and a remainder of 6e-08.
