We're dividing 538118 by 61 
The aim is to understand the frequency of 61 in 538118.

On to step 1:
5 divided by 61 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 61

Going ahead to step 2:
If we divide 53 by 61, we get 0 and a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 61

On to step 3:
538 divided by 61 is 8 with a remainder of 50.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 488 from 538 leaves us with 50.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 61

On to step 4:
If we divide 501 by 61, we get 8 and a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 88.0
If we subtract 488 from 501, we get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 61

Step 5:
When dividing 131 by 61, we get 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 882.0
If we take 122 away from 131, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 61

Step 6:
The number 61 fits into 98 1 times, leaving a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 8821.0
Subtracting 61 from 98 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 7:
61 can be fit into 370 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 8821.6
Deduct 366 from 370 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 61, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 8821.6
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
61 goes into 400 6 times with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 8821.606
If we subtract 366 from 400, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
The number 61 fits into 340 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 8821.6065
The remainder is 35 after subtracting 305 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
61 can be fit into 350 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 8821.60655
Subtract 305 from 350 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 8821.60655 with a remainder of 4.5e-05.
