We divide 513615 by 87
Let's see how many times 87 fits into 513615.

Advancing to step 1:
87 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 87

Advancing to step 2:
51 divided by 87 is 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (3) from the dividend, attach it to 51 and continue: 513 / 87

On to step 3:
513 divided by 87 is 5 with a remainder of 78.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 435 from 513 leaves us with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 87

Moving on to step 4:
87 can be fit into 786 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtract 783 from 786 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 87

Advancing to step 5:
87 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 590.0
Subtract 0 from 31 to get 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 87

Let's proceed to step 6:
The number 87 fits into 315 3 times, leaving a remainder of 54.
The next digit of our result is 3. 
Result so far: 5903.0
Subtracting 261 from 315 leaves us 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 7:
87 can be fit into 540 6 times, resulting in a remainder of 18.
The next digit of our result is 6. 
Result so far: 5903.6
The remainder is 18 after subtracting 522 from 540.
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 8:
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: 5903.62
If we take 174 away from 180, we end up 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 9:
If we divide 60 by 87, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5903.62
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
600 divided by 87 is 6 with a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 5903.6206
Deduct 522 from 600 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
If we divide 780 by 87, we get 8 and a remainder of 84.
The next digit of our result is 8. 
Result so far: 5903.62068
Subtracting 696 from 780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
87 can be fit into 840 9 times, resulting in a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 5903.620689
The remainder is 57 after subtracting 783 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 13:
87 goes into 570 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 5903.6206896
The remainder is 48 after subtracting 522 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
480 divided by 87 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 5903.62068965
If we take 435 away from 480, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 5903.62068965, with a leftover of 4.5e-08.
