171850 ÷ 61 
The aim is to understand the frequency of 61 in 171850.

Let's proceed to step 1:
61 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 61

Advancing to step 2:
61 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 61

Let's proceed to step 3:
61 can be fit into 171 2 times, resulting in a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 122 from 171 and we're left with 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 61

Going ahead to step 4:
61 goes into 498 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 28.0
If we subtract 488 from 498, we get 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 61

Going ahead to step 5:
When dividing 105 by 61, we get 1 with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
Subtracting 61 from 105 leaves us with 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 61

Advancing to step 6:
61 can be fit into 440 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 2817.0
If we subtract 427 from 440, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
130 divided by 61 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2817.2
If we subtract 122 from 130, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
61 can be fit into 80 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 2817.21
Subtract 61 from 80 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
61 goes into 190 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 2817.213
If we subtract 183 from 190, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
The number 61 fits into 70 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 2817.2131
The remainder is 9 after subtracting 61 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
90 divided by 61 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 2817.21311
If we take 61 away from 90, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 2817.21311 with a balance of 2.9e-05.
