Let's divide 577881 by 87
We want to figure out the number of times 577881 can be divided by 87.

Going ahead to step 1:
The number 87 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 87

Advancing to step 2:
87 can be fit into 57 0 times, resulting in a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 87

On to step 3:
If we divide 577 by 87, we get 6 and a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 522 from 577 leaves us with 55.
Include the next digit (8) from the dividend after 55, then repeat: 558 / 87

Advancing to step 4:
If we divide 558 by 87, we get 6 and a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Subtract 522 from 558 to get 36.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 87

Let's proceed to step 5:
368 divided by 87 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 664.0
If we subtract 348 from 368, we get 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 87

Going ahead to step 6:
If we divide 201 by 87, we get 2 and a remainder of 27.
The next digit of our result is 2. 
Result so far: 6642.0
The remainder is 27 after subtracting 174 from 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
270 divided by 87 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 6642.3
Subtract 261 from 270 to 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:
If we divide 90 by 87, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 6642.31
If we take 87 away from 90, we end up 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.

Going ahead to step 9:
If we divide 30 by 87, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6642.31
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
If we divide 300 by 87, we get 3 and a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 6642.3103
Subtract 261 from 300 to get 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.
Use 4 as the next digit of our solution. 
Result so far: 6642.31034
Subtracting 348 from 390 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
If we divide 420 by 87, we get 4 and a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 6642.310344
Subtracting 348 from 420 leaves us 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 final result is 6642.310344 with a remainder of 7.2e-06.
