688351 ÷ 61 
The aim is to understand the frequency of 61 in 688351.

On to step 1:
61 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 61

Going ahead to step 2:
The number 61 fits into 68 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 61 from 68 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 61

On to step 3:
61 can be fit into 78 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 61 from 78, we get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 61

Going ahead to step 4:
The number 61 fits into 173 2 times, leaving a remainder of 51.
The next digit of our result is 2. 
Result so far: 112.0
The remainder is 51 after subtracting 122 from 173.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 61

On to step 5:
If we divide 515 by 61, we get 8 and a remainder of 27.
The next digit of our result is 8. 
Result so far: 1128.0
Subtracting 488 from 515 leaves us with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 61

Moving on to step 6:
If we divide 271 by 61, we get 4 and a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 11284.0
Subtract 244 from 271 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
The number 61 fits into 270 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 11284.4
The remainder is 26 after subtracting 244 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
The number 61 fits into 260 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 11284.44
Subtracting 244 from 260 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 11284.44 with a remaining 0.016.
