572175 ÷ 61 
The aim is to understand the frequency of 61 in 572175.

On to step 1:
The number 61 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 61

On to step 2:
If we divide 57 by 61, we get 0 and a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Fetch the next digit (2) from the dividend, attach it to 57 and continue: 572 / 61

Step 3:
When dividing 572 by 61, we get 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 549 away from 572, we end up with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 61

On to step 4:
If we divide 231 by 61, we get 3 and a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Deduct 183 from 231 and we're left with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 61

Let's proceed to step 5:
61 can be fit into 487 7 times, resulting in a remainder of 60.
The next digit of our result is 7. 
Result so far: 937.0
The remainder is 60 after subtracting 427 from 487.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 61

Let's proceed to step 6:
605 divided by 61 is 9 with a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 9379.0
The remainder is 56 after subtracting 549 from 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
560 divided by 61 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9379.9
If we take 549 away from 560, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 8:
61 can be fit into 110 1 times, resulting in a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 9379.91
Subtracting 61 from 110 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 9:
If we divide 490 by 61, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 9379.918
Subtract 488 from 490 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
61 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9379.918
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 61, we get 3 and a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 9379.91803
Deduct 183 from 200 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
The number 61 fits into 170 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 9379.918032
Subtracting 122 from 170 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 13:
480 divided by 61 is 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 9379.9180327
The remainder is 53 after subtracting 427 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 14:
The number 61 fits into 530 8 times, leaving a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 9379.91803278
Subtracting 488 from 530 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 9379.91803278, with a leftover of 4.2e-08.
