We divide 877821 by 77
We want to divide 877821 by 77.

Let's proceed to step 1:
The number 77 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 77

On to step 2:
When dividing 87 by 77, we get 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 87 to get 10.
Fetch the next digit (7) from the dividend, attach it to 10 and continue: 107 / 77

Advancing to step 3:
77 goes into 107 1 times with a remainder of 30.
The next digit of our result is 1. 
Result so far: 11.0
If we take 77 away from 107, we end up with 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 77

Moving on to step 4:
308 divided by 77 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 114.0
If we take 308 away from 308, we end up with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 77

Advancing to step 5:
If we divide 2 by 77, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 1140.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 77

Moving on to step 6:
21 divided by 77 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 11400.0
The remainder is 21 after subtracting 0 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
77 goes into 210 2 times with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 11400.2
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
The number 77 fits into 560 7 times, leaving a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 11400.27
The remainder is 21 after subtracting 539 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
If we divide 210 by 77, we get 2 and a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 11400.272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
The number 77 fits into 560 7 times, leaving a remainder of 21.
The next digit of our result is 7. 
Result so far: 11400.2727
If we take 539 away from 560, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
77 can be fit into 210 2 times, resulting in a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 11400.27272
The remainder is 56 after subtracting 154 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
77 can be fit into 560 7 times, resulting in a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 11400.272727
If we subtract 539 from 560, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
If we divide 210 by 77, we get 2 and a remainder of 56.
The next digit of our result is 2. 
Result so far: 11400.2727272
If we subtract 154 from 210, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 14:
77 goes into 560 7 times with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 11400.27272727
Deduct 539 from 560 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 11400.27272727 with a remainder of 2.1e-08.
