We divide 869866 by 77
We want to divide 869866 by 77.

Advancing to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 77

Let's proceed to step 2:
77 goes into 86 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 77 from 86 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 77

Going ahead to step 3:
77 can be fit into 99 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 77 from 99, we get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 77

Going ahead to step 4:
When dividing 228 by 77, we get 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 112.0
The remainder is 74 after subtracting 154 from 228.
Grab the next digit (6) from the dividend, add it to 74, then carry on: 746 / 77

Going ahead to step 5:
When dividing 746 by 77, we get 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 1129.0
Subtract 693 from 746 to get 53.
Take the next digit (6) from the dividend and append it to 53, then repeat: 536 / 77

Advancing to step 6:
536 divided by 77 is 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 11296.0
Subtract 462 from 536 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 7:
740 divided by 77 is 9 with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 11296.9
Subtracting 693 from 740 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
470 divided by 77 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 11296.96
Subtracting 462 from 470 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
77 goes into 80 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11296.961
Deduct 77 from 80 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
When dividing 30 by 77, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 11296.961
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
77 can be fit into 300 3 times, resulting in a remainder of 69.
The next digit of our result is 3. 
Result so far: 11296.96103
If we subtract 231 from 300, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 12:
77 can be fit into 690 8 times, resulting in a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 11296.961038
The remainder is 74 after subtracting 616 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 13:
When dividing 740 by 77, we get 9 with a remainder of 47.
Record the quotient 9 as the next digit in the result. 
Result so far: 11296.9610389
Subtracting 693 from 740 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
The number 77 fits into 470 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 11296.96103896
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 11296.96103896 and a remainder of 8e-09.
