Let's divide 691593 by 7
The aim is to understand the frequency of 7 in 691593.

Going ahead to step 1:
6 divided by 7 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 7

Advancing to step 2:
7 goes into 69 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 63 from 69, we get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 7

Let's proceed to step 3:
The number 7 fits into 61 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we subtract 56 from 61, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 7

On to step 4:
7 goes into 55 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
If we take 49 away from 55, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 7

Moving on to step 5:
If we divide 69 by 7, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 9879.0
The remainder is 6 after subtracting 63 from 69.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 7

Going ahead to step 6:
If we divide 63 by 7, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 98799.0
Subtract 63 from 63 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
7 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 98799.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 98799.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 98799.0, and the remainder is 0.0.
