574651 ÷ 61 
The aim is to understand the frequency of 61 in 574651.

On to step 1:
5 divided by 61 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 61

Moving on to step 2:
61 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (4) from the dividend, add it to 57, then carry on: 574 / 61

Advancing to step 3:
61 goes into 574 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 549 away from 574, we end up with 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 61

Advancing to step 4:
61 can be fit into 256 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 94.0
The remainder is 12 after subtracting 244 from 256.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 61

Step 5:
125 divided by 61 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 942.0
Subtract 122 from 125 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 61

Let's proceed to step 6:
The number 61 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 9420.0
Subtract 0 from 31 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
61 can be fit into 310 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 9420.5
If we subtract 305 from 310, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
When dividing 50 by 61, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 9420.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
61 can be fit into 500 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 9420.508
Subtracting 488 from 500 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
120 divided by 61 is 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 9420.5081
The remainder is 59 after subtracting 61 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 11:
When dividing 590 by 61, we get 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 9420.50819
Subtract 549 from 590 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 12:
The number 61 fits into 410 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 9420.508196
The remainder is 44 after subtracting 366 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
If we divide 440 by 61, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 9420.5081967
Subtracting 427 from 440 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
If we divide 130 by 61, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 9420.50819672
Deduct 122 from 130 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 9420.50819672, with a leftover of 8e-09.
