Let's divide 77799 by 7
We're looking to find how many times 7 goes into 77799.

On to step 1:
If we divide 7 by 7, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 7 from 7.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 7

Moving on to step 2:
If we divide 7 by 7, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 7 from 7 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 7

Going ahead to step 3:
When dividing 7 by 7, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 111.0
The remainder is 0 after subtracting 7 from 7.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 7

Moving on to step 4:
If we divide 9 by 7, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1111.0
If we subtract 7 from 9, we get 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 7

Moving on to step 5:
7 can be fit into 29 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 11114.0
Subtracting 28 from 29 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
If we divide 10 by 7, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 11114.1
Subtracting 7 from 10 leaves us 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.

On to step 7:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 11114.14
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 11114.142
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 11114.1428
Subtracting 56 from 60 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.

Step 10:
40 divided by 7 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 11114.14285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 11114.142857
Subtract 49 from 50 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 11114.1428571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 11114.14285714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 11114.14285714, with a leftover of 2e-09.
