We divide 320404 by 87
We want to divide 320404 by 87.

Moving on to step 1:
When dividing 3 by 87, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 87

Let's proceed to step 2:
The number 87 fits into 32 0 times, leaving a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 32, we end up with 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 87

Going ahead to step 3:
87 goes into 320 3 times with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 261 from 320, we get 59.
Grab the next digit (4) from the dividend, add it to 59, then carry on: 594 / 87

Going ahead to step 4:
The number 87 fits into 594 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 72 after subtracting 522 from 594.
Bring next digit (0) of the dividend behind the 72 and repeat the process: 720 / 87

Step 5:
87 goes into 720 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 368.0
If we take 696 away from 720, we end up with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 87

Step 6:
87 goes into 244 2 times with a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 3682.0
If we take 174 away from 244, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
87 goes into 700 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 3682.8
Deduct 696 from 700 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 87, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3682.8
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
87 goes into 400 4 times with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 3682.804
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
520 divided by 87 is 5 with a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 3682.8045
If we take 435 away from 520, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
If we divide 850 by 87, we get 9 and a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 3682.80459
If we take 783 away from 850, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 12:
If we divide 670 by 87, we get 7 and a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 3682.804597
Subtract 609 from 670 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 13:
The number 87 fits into 610 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 3682.8045977
Subtract 609 from 610 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 3682.8045977 with a remainder of 1e-08.
