815107 ÷ 77 
Our goal is to divide 815107 by 77.

On to step 1:
The number 77 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 77

Going ahead to step 2:
81 divided by 77 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 77 from 81 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 77

Let's proceed to step 3:
77 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 45 to get 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 77

Let's proceed to step 4:
451 divided by 77 is 5 with a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we take 385 away from 451, we end up with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 77

On to step 5:
77 goes into 660 8 times with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 1058.0
Subtracting 616 from 660 leaves us with 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 77

Let's proceed to step 6:
The number 77 fits into 447 5 times, leaving a remainder of 62.
Put 5 as the next digit of the answer. 
Result so far: 10585.0
The remainder is 62 after subtracting 385 from 447.
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 7:
When dividing 620 by 77, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10585.8
Deduct 616 from 620 and we're left 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.

Let's proceed to step 8:
77 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 10585.8
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 77, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10585.805
Subtract 385 from 400 to 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 10:
When dividing 150 by 77, we get 1 with a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 10585.8051
Subtract 77 from 150 to 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.

Advancing to step 11:
77 goes into 730 9 times with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 10585.80519
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.

Going ahead to step 12:
If we divide 370 by 77, we get 4 and a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 10585.805194
Subtracting 308 from 370 leaves us 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.

Moving on to step 13:
If we divide 620 by 77, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10585.8051948
Subtract 616 from 620 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 77, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 10585.8051948
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 10585.8051948, and the remainder is 4e-08.
