We're dividing 789171 by 61 
The aim is to understand the frequency of 61 in 789171.

Advancing to step 1:
The number 61 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 61

Step 2:
The number 61 fits into 78 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 61 away from 78, we end up with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 61

On to step 3:
179 divided by 61 is 2 with a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 122 from 179 leaves us with 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 61

Let's proceed to step 4:
61 goes into 571 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we subtract 549 from 571, we get 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 61

Step 5:
61 goes into 227 3 times with a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 1293.0
Deduct 183 from 227 and we're left with 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 61

Let's proceed to step 6:
441 divided by 61 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 12937.0
Subtract 427 from 441 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
61 can be fit into 140 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 12937.2
Subtracting 122 from 140 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
The number 61 fits into 180 2 times, leaving a remainder of 58.
The next digit of our result is 2. 
Result so far: 12937.22
Subtract 122 from 180 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 12937.22 and a remainder of 0.058.
