618393 divided by 87 
We want to divide 618393 by 87.

Moving on to step 1:
87 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 87

Going ahead to step 2:
The number 87 fits into 61 0 times, leaving a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 87

Step 3:
If we divide 618 by 87, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 609 from 618, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 87

Advancing to step 4:
If we divide 93 by 87, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 87 from 93 and we're left with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 87

On to step 5:
87 can be fit into 69 0 times, resulting in a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 710.0
Deduct 0 from 69 and we're left with 69.
Bring next digit (3) of the dividend behind the 69 and repeat the process: 693 / 87

Step 6:
When dividing 693 by 87, we get 7 with a remainder of 84.
Use 7 as the next digit of our solution. 
Result so far: 7107.0
If we subtract 609 from 693, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 7:
87 can be fit into 840 9 times, resulting in a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 7107.9
Subtracting 783 from 840 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 8:
87 can be fit into 570 6 times, resulting in a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 7107.96
Deduct 522 from 570 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
480 divided by 87 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 7107.965
Subtracting 435 from 480 leaves us 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.

Moving on to step 10:
87 goes into 450 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7107.9655
Subtracting 435 from 450 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 7107.9655, with a leftover of 0.00015.
