869153 ÷ 77 
Our goal is to divide 869153 by 77.

Advancing to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 77

Going ahead to step 2:
The number 77 fits into 86 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 77 from 86 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 77

Advancing to step 3:
If we divide 99 by 77, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 22 after subtracting 77 from 99.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 77

On to step 4:
77 goes into 221 2 times with a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 112.0
If we subtract 154 from 221, we get 67.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 77

On to step 5:
77 can be fit into 675 8 times, resulting in a remainder of 59.
The next digit of our result is 8. 
Result so far: 1128.0
Subtract 616 from 675 to get 59.
Fetch the next digit (3) from the dividend, attach it to 59 and continue: 593 / 77

Let's proceed to step 6:
77 can be fit into 593 7 times, resulting in a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 11287.0
Subtract 539 from 593 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
77 can be fit into 540 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 11287.7
Subtracting 539 from 540 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
The number 77 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 11287.7
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
77 can be fit into 100 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 11287.701
Subtract 77 from 100 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
The number 77 fits into 230 2 times, leaving a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 11287.7012
The remainder is 76 after subtracting 154 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
77 goes into 760 9 times with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 11287.70129
Subtracting 693 from 760 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 12:
When dividing 670 by 77, we get 8 with a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 11287.701298
The remainder is 54 after subtracting 616 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
77 goes into 540 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 11287.7012987
The remainder is 1 after subtracting 539 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
77 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 11287.7012987
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 11287.7012987, with a leftover of 1e-08.
