647539 divided by 61 
The aim is to understand the frequency of 61 in 647539.

Moving on to step 1:
6 divided by 61 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 61

Advancing to step 2:
64 divided by 61 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 61 from 64 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 61

On to step 3:
61 goes into 37 0 times with a remainder of 37.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 37 and we're left with 37.
Append the next digit (5) from the dividend to 37 and continue with: 375 / 61

Let's proceed to step 4:
375 divided by 61 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Subtract 366 from 375 to get 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 61

Advancing to step 5:
The number 61 fits into 93 1 times, leaving a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1061.0
Subtracting 61 from 93 leaves us with 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 61

On to step 6:
61 can be fit into 329 5 times, resulting in a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 10615.0
Deduct 305 from 329 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
61 can be fit into 240 3 times, resulting in a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 10615.3
The remainder is 57 after subtracting 183 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 8:
61 goes into 570 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 10615.39
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.

Step 9:
210 divided by 61 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 10615.393
The remainder is 27 after subtracting 183 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 10:
If we divide 270 by 61, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 10615.3934
Subtracting 244 from 270 leaves us 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.

Step 11:
If we divide 260 by 61, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 10615.39344
Subtract 244 from 260 to get 16.
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 10615.39344 and a remainder of 1.6e-05.
