We divide 877815 by 77
We want to divide 877815 by 77.

Advancing 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
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 77

Advancing to step 2:
When dividing 87 by 77, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 10 after subtracting 77 from 87.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 77

On to step 3:
When dividing 107 by 77, we get 1 with a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 77 from 107 and we're left with 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 77

On to step 4:
The number 77 fits into 308 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtracting 308 from 308 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 77

On to step 5:
77 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 1140.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 77

Advancing to step 6:
If we divide 15 by 77, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 11400.0
If we subtract 0 from 15, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 77 is 1 with a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 11400.1
Subtracting 77 from 150 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 8:
The number 77 fits into 730 9 times, leaving a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 11400.19
Subtracting 693 from 730 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
The number 77 fits into 370 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 11400.194
If we take 308 away from 370, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
The number 77 fits into 620 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 11400.1948
Subtracting 616 from 620 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
The number 77 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 11400.1948
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
77 goes into 400 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 11400.194805
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
The number 77 fits into 150 1 times, leaving a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 11400.1948051
If we subtract 77 from 150, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 14:
The number 77 fits into 730 9 times, leaving a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 11400.19480519
If we take 693 away from 730, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Our division results in 11400.19480519 with a remaining 3.7e-08.
