847931 ÷ 77 
Our goal is to divide 847931 by 77.

Step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 77

Going ahead to step 2:
84 divided by 77 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 77 away from 84, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 77

Advancing to step 3:
77 goes into 77 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 77 from 77 leaves us with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 77

Moving on to step 4:
When dividing 9 by 77, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we take 0 away from 9, we end up with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 77

Advancing to step 5:
93 divided by 77 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1101.0
Deduct 77 from 93 and we're left with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 77

On to step 6:
The number 77 fits into 161 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 11012.0
The remainder is 7 after subtracting 154 from 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 77, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 11012.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
The number 77 fits into 700 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 11012.09
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
The number 77 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 11012.09
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 11012.0909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
77 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 11012.0909
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
When dividing 700 by 77, we get 9 with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 11012.090909
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
77 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 11012.090909
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
77 goes into 700 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 11012.09090909
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 11012.09090909 with a remaining 7e-09.
