Let's divide 404403 by 87
We want to figure out the number of times 404403 can be divided by 87.

Advancing to step 1:
4 divided by 87 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 87

Moving on to step 2:
The number 87 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 87

On to step 3:
87 goes into 404 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 348 from 404 to get 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 87

Let's proceed to step 4:
The number 87 fits into 564 6 times, leaving a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
If we subtract 522 from 564, we get 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 87

Step 5:
If we divide 420 by 87, we get 4 and a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 464.0
If we subtract 348 from 420, we get 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 87

Moving on to step 6:
If we divide 723 by 87, we get 8 and a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 4648.0
If we subtract 696 from 723, we 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.

On to step 7:
87 can be fit into 270 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 4648.3
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
When dividing 90 by 87, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4648.31
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
The number 87 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 4648.31
The remainder is 30 after subtracting 0 from 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 10:
87 can be fit into 300 3 times, resulting in a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 4648.3103
If we take 261 away from 300, we end up 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.

Step 11:
When dividing 390 by 87, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 4648.31034
Subtract 348 from 390 to 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.

Moving on to step 12:
The number 87 fits into 420 4 times, leaving a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 4648.310344
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.

The final outcome is 4648.310344, with a leftover of 7.2e-06.
