641973 ÷ 87 
Let's see how many times 87 fits into 641973.

Advancing to step 1:
When dividing 6 by 87, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 87

Step 2:
87 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 87

On to step 3:
87 can be fit into 641 7 times, resulting in a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 609 from 641, we get 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 87

Let's proceed to step 4:
329 divided by 87 is 3 with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtract 261 from 329 to get 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 87

Going ahead to step 5:
87 goes into 687 7 times with a remainder of 78.
The next digit of our result is 7. 
Result so far: 737.0
Subtracting 609 from 687 leaves us with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 87

Moving on to step 6:
If we divide 783 by 87, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 7379.0
If we subtract 783 from 783, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 87 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 7379.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 87 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7379.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 7379.0 with a remainder of 0.0.
