61691 ÷ 7 
The aim is to understand the frequency of 7 in 61691.

Advancing to step 1:
The number 7 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 7

Step 2:
The number 7 fits into 61 8 times, leaving a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 56 from 61 and we're left with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 7

On to step 3:
7 can be fit into 56 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 88.0
If we take 56 away from 56, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 7

Let's proceed to step 4:
7 goes into 9 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 881.0
Deduct 7 from 9 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 7

Advancing to step 5:
7 can be fit into 21 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 8813.0
If we subtract 21 from 21, 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.

Step 6:
When dividing 0 by 7, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8813.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8813.0
The remainder is 0 after subtracting 0 from 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 final outcome is 8813.0, with a leftover of 0.0.
