Let's divide 521862 by 87
Let's see how many times 87 fits into 521862.

Step 1:
If we divide 5 by 87, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 87

Let's proceed to step 2:
If we divide 52 by 87, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 87

Let's proceed to step 3:
87 goes into 521 5 times with a remainder of 86.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 86 after subtracting 435 from 521.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 87

Let's proceed to step 4:
87 goes into 868 9 times with a remainder of 85.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtracting 783 from 868 leaves us with 85.
Grab the next digit (6) from the dividend, add it to 85, then carry on: 856 / 87

On to step 5:
87 can be fit into 856 9 times, resulting in a remainder of 73.
Use 9 as the next digit of our solution. 
Result so far: 599.0
If we subtract 783 from 856, we get 73.
Take the next digit (2) from the dividend and append it to 73, then repeat: 732 / 87

Moving on to step 6:
When dividing 732 by 87, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 5998.0
Subtract 696 from 732 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
87 goes into 360 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 5998.4
The remainder is 12 after subtracting 348 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
87 can be fit into 120 1 times, resulting in a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 5998.41
Subtract 87 from 120 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 9:
87 can be fit into 330 3 times, resulting in a remainder of 69.
The next digit of our result is 3. 
Result so far: 5998.413
If we subtract 261 from 330, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 10:
87 goes into 690 7 times with a remainder of 81.
The next digit of our result is 7. 
Result so far: 5998.4137
If we take 609 away from 690, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 11:
87 can be fit into 810 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 5998.41379
Subtracting 783 from 810 leaves us with 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 12:
87 goes into 270 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 5998.413793
If we subtract 261 from 270, we 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.

Moving on to step 13:
87 can be fit into 90 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 5998.4137931
Deduct 87 from 90 and we're left 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.

Advancing to step 14:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 5998.4137931
Subtracting 0 from 30 leaves us 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.

The quotient of the division is 5998.4137931, and the remainder is 3e-08.
