18870977 ÷ 877 
Our goal is to divide 18870977 by 877.

Going ahead to step 1:
When dividing 1 by 877, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 877

Step 2:
877 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 877

Advancing to step 3:
877 goes into 188 0 times with a remainder of 188.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 188, we end up with 188.
Fetch the next digit (7) from the dividend, attach it to 188 and continue: 1887 / 877

Advancing to step 4:
If we divide 1887 by 877, we get 2 and a remainder of 133.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1754 from 1887 and we're left with 133.
Take the next digit (0) from the dividend and append it to 133, then repeat: 1330 / 877

Going ahead to step 5:
If we divide 1330 by 877, we get 1 and a remainder of 453.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 877 from 1330 to get 453.
Take the next digit (9) from the dividend and append it to 453, then repeat: 4539 / 877

Moving on to step 6:
877 goes into 4539 5 times with a remainder of 154.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
Subtracting 4385 from 4539 leaves us with 154.
Take the next digit (7) from the dividend and append it to 154, then repeat: 1547 / 877

Moving on to step 7:
877 can be fit into 1547 1 times, resulting in a remainder of 670.
Write down 1 as next digit of the result. 
Result so far: 2151.0
Subtracting 877 from 1547 leaves us with 670.
Grab the next digit (7) from the dividend, add it to 670, then carry on: 6707 / 877

On to step 8:
877 can be fit into 6707 7 times, resulting in a remainder of 568.
The number 7 becomes the next digit in our result. 
Result so far: 21517.0
If we take 6139 away from 6707, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 9:
877 can be fit into 5680 6 times, resulting in a remainder of 418.
The next digit of our result is 6. 
Result so far: 21517.6
If we take 5262 away from 5680, we end up with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 10:
877 goes into 4180 4 times with a remainder of 672.
Put 4 as the next digit of the answer. 
Result so far: 21517.64
Deduct 3508 from 4180 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Step 11:
The number 877 fits into 6720 7 times, leaving a remainder of 581.
The next digit of our result is 7. 
Result so far: 21517.647
The remainder is 581 after subtracting 6139 from 6720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Advancing to step 12:
If we divide 5810 by 877, we get 6 and a remainder of 548.
Use 6 as the next digit of our solution. 
Result so far: 21517.6476
Subtracting 5262 from 5810 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Step 13:
5480 divided by 877 is 6 with a remainder of 218.
Put 6 as the next digit of the answer. 
Result so far: 21517.64766
The remainder is 218 after subtracting 5262 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

The final outcome is 21517.64766, with a leftover of 0.000218.
