66169070 divided by 877 
We want to divide 66169070 by 877.

On to step 1:
6 divided by 877 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 877

Let's proceed to step 2:
877 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 877

On to step 3:
If we divide 661 by 877, we get 0 and a remainder of 661.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 661, we get 661.
Take the next digit (6) from the dividend and append it to 661, then repeat: 6616 / 877

Let's proceed to step 4:
6616 divided by 877 is 7 with a remainder of 477.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 6139 from 6616 leaves us with 477.
Fetch the next digit (9) from the dividend, attach it to 477 and continue: 4779 / 877

Going ahead to step 5:
4779 divided by 877 is 5 with a remainder of 394.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we subtract 4385 from 4779, we get 394.
Take the next digit (0) from the dividend and append it to 394, then repeat: 3940 / 877

Going ahead to step 6:
877 can be fit into 3940 4 times, resulting in a remainder of 432.
Use 4 as the next digit of our solution. 
Result so far: 754.0
Subtract 3508 from 3940 to get 432.
Append the next digit (7) from the dividend to 432 and continue with: 4327 / 877

Step 7:
The number 877 fits into 4327 4 times, leaving a remainder of 819.
Use 4 as the next digit of our solution. 
Result so far: 7544.0
The remainder is 819 after subtracting 3508 from 4327.
Take the next digit (0) from the dividend and append it to 819, then repeat: 8190 / 877

Step 8:
877 can be fit into 8190 9 times, resulting in a remainder of 297.
Write down 9 as next digit of the result. 
Result so far: 75449.0
If we subtract 7893 from 8190, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Advancing to step 9:
877 can be fit into 2970 3 times, resulting in a remainder of 339.
Use 3 as the next digit of our solution. 
Result so far: 75449.3
Subtract 2631 from 2970 to get 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 10:
The number 877 fits into 3390 3 times, leaving a remainder of 759.
Use 3 as the next digit of our solution. 
Result so far: 75449.33
Subtracting 2631 from 3390 leaves us with 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

The final outcome is 75449.33, with a leftover of 0.759.
