We're dividing 816539 by 77 
We want to figure out the number of times 816539 can be divided by 77.

Moving on to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 77

Moving on to step 2:
When dividing 81 by 77, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 77 from 81 leaves us with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 77

On to step 3:
If we divide 46 by 77, we get 0 and a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 46, we get 46.
Grab the next digit (5) from the dividend, add it to 46, then carry on: 465 / 77

On to step 4:
If we divide 465 by 77, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 106.0
If we subtract 462 from 465, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 77

Let's proceed to step 5:
When dividing 33 by 77, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 1060.0
Subtract 0 from 33 to get 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 77

Let's proceed to step 6:
339 divided by 77 is 4 with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 10604.0
Deduct 308 from 339 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
The number 77 fits into 310 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 10604.4
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
The number 77 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 10604.4
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
The number 77 fits into 200 2 times, leaving a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 10604.402
The remainder is 46 after subtracting 154 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
If we divide 460 by 77, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 10604.4025
Deduct 385 from 460 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 11:
750 divided by 77 is 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 10604.40259
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 12:
If we divide 570 by 77, we get 7 and a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 10604.402597
If we take 539 away from 570, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 13:
77 goes into 310 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 10604.4025974
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
If we divide 20 by 77, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10604.4025974
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 10604.4025974 with a remaining 2e-08.
