We're dividing 770772 by 7 
The aim is to understand the frequency of 7 in 770772.

Let's proceed to step 1:
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: 1.0
The remainder is 0 after subtracting 7 from 7.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 7

On to step 2:
When dividing 7 by 7, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 0 after subtracting 7 from 7.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 7

Going ahead to step 3:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 7

Advancing to step 4:
7 divided by 7 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1101.0
The remainder is 0 after subtracting 7 from 7.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 7

On to step 5:
When dividing 7 by 7, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11011.0
If we take 7 away from 7, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 7

Let's proceed to step 6:
7 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 110110.0
Subtract 0 from 2 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.

Let's proceed to step 7:
20 divided by 7 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 110110.2
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.

Going ahead to step 8:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 110110.28
Subtract 56 from 60 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.

Let's proceed to step 9:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 110110.285
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.

Advancing to step 10:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 110110.2857
If we take 49 away from 50, we end up 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.

Moving on to step 11:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 110110.28571
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.

Moving on to step 12:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 110110.285714
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.

Let's proceed to step 13:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 110110.2857142
Deduct 14 from 20 and we're left 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 14:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 110110.28571428
Subtract 56 from 60 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.

The quotient of the division is 110110.28571428, and the remainder is 4e-09.
