We divide 66687026 by 861
Our goal is to divide 66687026 by 861.

Moving on to step 1:
6 divided by 861 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 861

Let's proceed to step 2:
When dividing 66 by 861, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 861

Advancing to step 3:
If we divide 666 by 861, we get 0 and a remainder of 666.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 666 after subtracting 0 from 666.
Fetch the next digit (8) from the dividend, attach it to 666 and continue: 6668 / 861

Going ahead to step 4:
861 goes into 6668 7 times with a remainder of 641.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 6027 from 6668 to get 641.
Fetch the next digit (7) from the dividend, attach it to 641 and continue: 6417 / 861

On to step 5:
861 can be fit into 6417 7 times, resulting in a remainder of 390.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
If we subtract 6027 from 6417, we get 390.
Append the next digit (0) from the dividend to 390 and continue with: 3900 / 861

Moving on to step 6:
861 can be fit into 3900 4 times, resulting in a remainder of 456.
Use 4 as the next digit of our solution. 
Result so far: 774.0
The remainder is 456 after subtracting 3444 from 3900.
Fetch the next digit (2) from the dividend, attach it to 456 and continue: 4562 / 861

Moving on to step 7:
If we divide 4562 by 861, we get 5 and a remainder of 257.
Record the quotient 5 as the next digit in the result. 
Result so far: 7745.0
If we take 4305 away from 4562, we end up with 257.
Grab the next digit (6) from the dividend, add it to 257, then carry on: 2576 / 861

Moving on to step 8:
2576 divided by 861 is 2 with a remainder of 854.
Record the quotient 2 as the next digit in the result. 
Result so far: 77452.0
If we subtract 1722 from 2576, we get 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Advancing to step 9:
8540 divided by 861 is 9 with a remainder of 791.
The next digit of our result is 9. 
Result so far: 77452.9
If we subtract 7749 from 8540, we get 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Let's proceed to step 10:
7910 divided by 861 is 9 with a remainder of 161.
Record the quotient 9 as the next digit in the result. 
Result so far: 77452.99
Subtract 7749 from 7910 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

The final result is 77452.99 with a remainder of 0.161.
