Let's divide 864837 by 61
The aim is to understand the frequency of 61 in 864837.

Going ahead to step 1:
If we divide 8 by 61, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 61

On to step 2:
When dividing 86 by 61, we get 1 with a remainder of 25.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 61 from 86 and we're left with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 61

Step 3:
If we divide 254 by 61, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 244 from 254 and we're left with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 61

Going ahead to step 4:
61 can be fit into 108 1 times, resulting in a remainder of 47.
The next digit of our result is 1. 
Result so far: 141.0
Deduct 61 from 108 and we're left with 47.
Bring next digit (3) of the dividend behind the 47 and repeat the process: 473 / 61

Going ahead to step 5:
If we divide 473 by 61, we get 7 and a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 1417.0
The remainder is 46 after subtracting 427 from 473.
Append the next digit (7) from the dividend to 46 and continue with: 467 / 61

On to step 6:
61 can be fit into 467 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 14177.0
Deduct 427 from 467 and we're left 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.

Advancing to step 7:
400 divided by 61 is 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 14177.6
Subtracting 366 from 400 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
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: 14177.65
Subtracting 305 from 340 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
61 goes into 350 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 14177.655
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.

After the division, we end up with 14177.655 and a remainder of 0.0045.
