We're dividing 72330481 by 261 
The aim is to understand the frequency of 261 in 72330481.

Going ahead to step 1:
When dividing 7 by 261, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 261

On to step 2:
When dividing 72 by 261, we get 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 261

Let's proceed to step 3:
If we divide 723 by 261, we get 2 and a remainder of 201.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 522 from 723 leaves us with 201.
Fetch the next digit (3) from the dividend, attach it to 201 and continue: 2013 / 261

Going ahead to step 4:
When dividing 2013 by 261, we get 7 with a remainder of 186.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
If we take 1827 away from 2013, we end up with 186.
Take the next digit (0) from the dividend and append it to 186, then repeat: 1860 / 261

Going ahead to step 5:
261 goes into 1860 7 times with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 277.0
If we subtract 1827 from 1860, we get 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 261

Advancing to step 6:
The number 261 fits into 334 1 times, leaving a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 2771.0
Subtract 261 from 334 to get 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 261

Going ahead to step 7:
If we divide 738 by 261, we get 2 and a remainder of 216.
The number 2 becomes the next digit in our result. 
Result so far: 27712.0
Deduct 522 from 738 and we're left with 216.
Bring next digit (1) of the dividend behind the 216 and repeat the process: 2161 / 261

On to step 8:
261 goes into 2161 8 times with a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 277128.0
If we subtract 2088 from 2161, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
261 goes into 730 2 times with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 277128.2
The remainder is 208 after subtracting 522 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 10:
261 goes into 2080 7 times with a remainder of 253.
The next digit of our result is 7. 
Result so far: 277128.27
If we take 1827 away from 2080, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 11:
2530 divided by 261 is 9 with a remainder of 181.
The number 9 becomes the next digit in our result. 
Result so far: 277128.279
If we take 2349 away from 2530, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 12:
The number 261 fits into 1810 6 times, leaving a remainder of 244.
Record the quotient 6 as the next digit in the result. 
Result so far: 277128.2796
If we subtract 1566 from 1810, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 13:
The number 261 fits into 2440 9 times, leaving a remainder of 91.
Use 9 as the next digit of our solution. 
Result so far: 277128.27969
Subtract 2349 from 2440 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 14:
910 divided by 261 is 3 with a remainder of 127.
The next digit of our result is 3. 
Result so far: 277128.279693
If we subtract 783 from 910, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 15:
261 can be fit into 1270 4 times, resulting in a remainder of 226.
Record the quotient 4 as the next digit in the result. 
Result so far: 277128.2796934
Subtracting 1044 from 1270 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 16:
When dividing 2260 by 261, we get 8 with a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 277128.27969348
If we take 2088 away from 2260, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The quotient of the division is 277128.27969348, and the remainder is 1.72e-07.
