We look at the division of 642804 by 87 
Our goal is to divide 642804 by 87.

Step 1:
If we divide 6 by 87, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 87

Step 2:
The number 87 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 87

Moving on to step 3:
87 goes into 642 7 times with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 33 after subtracting 609 from 642.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 87

Advancing to step 4:
When dividing 338 by 87, we get 3 with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we take 261 away from 338, we end up with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 87

Moving on to step 5:
When dividing 770 by 87, we get 8 with a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 738.0
Subtract 696 from 770 to get 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 87

Advancing to step 6:
If we divide 744 by 87, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 7388.0
Subtracting 696 from 744 leaves us 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.

Going ahead to step 7:
The number 87 fits into 480 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 7388.5
If we subtract 435 from 480, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
When dividing 450 by 87, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 7388.55
If we take 435 away from 450, we end up 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 result is 7388.55 with a remainder of 0.015.
