We look at the division of 154204 by 61 
The aim is to understand the frequency of 61 in 154204.

Advancing to step 1:
When dividing 1 by 61, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 61

Advancing to step 2:
61 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 61

Step 3:
61 can be fit into 154 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 122 away from 154, we end up with 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 61

On to step 4:
322 divided by 61 is 5 with a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtract 305 from 322 to get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 61

Step 5:
170 divided by 61 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 252.0
The remainder is 48 after subtracting 122 from 170.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 61

Advancing to step 6:
61 goes into 484 7 times with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 2527.0
Subtract 427 from 484 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
When dividing 570 by 61, we get 9 with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 2527.9
Subtracting 549 from 570 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
When dividing 210 by 61, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 2527.93
Subtract 183 from 210 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 9:
61 goes into 270 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 2527.934
Deduct 244 from 270 and we're left with 26.
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 10:
When dividing 260 by 61, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 2527.9344
The remainder is 16 after subtracting 244 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 2527.9344 and a remainder of 0.00016.
