We look at the division of 30166948 by 261 
The aim is to understand the frequency of 261 in 30166948.

Moving on to step 1:
When dividing 3 by 261, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 261

Let's proceed to step 2:
30 divided by 261 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Grab the next digit (1) from the dividend, add it to 30, then carry on: 301 / 261

Step 3:
The number 261 fits into 301 1 times, leaving a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 261 from 301, we get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 261

Step 4:
If we divide 406 by 261, we get 1 and a remainder of 145.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 261 from 406 and we're left with 145.
Grab the next digit (6) from the dividend, add it to 145, then carry on: 1456 / 261

Advancing to step 5:
If we divide 1456 by 261, we get 5 and a remainder of 151.
Put 5 as the next digit of the answer. 
Result so far: 115.0
The remainder is 151 after subtracting 1305 from 1456.
Fetch the next digit (9) from the dividend, attach it to 151 and continue: 1519 / 261

Going ahead to step 6:
When dividing 1519 by 261, we get 5 with a remainder of 214.
Write down 5 as next digit of the result. 
Result so far: 1155.0
If we subtract 1305 from 1519, we get 214.
Bring next digit (4) of the dividend behind the 214 and repeat the process: 2144 / 261

Going ahead to step 7:
2144 divided by 261 is 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 11558.0
Deduct 2088 from 2144 and we're left with 56.
Append the next digit (8) from the dividend to 56 and continue with: 568 / 261

On to step 8:
261 can be fit into 568 2 times, resulting in a remainder of 46.
The next digit of our result is 2. 
Result so far: 115582.0
Deduct 522 from 568 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
The number 261 fits into 460 1 times, leaving a remainder of 199.
The number 1 becomes the next digit in our result. 
Result so far: 115582.1
If we take 261 away from 460, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 10:
261 can be fit into 1990 7 times, resulting in a remainder of 163.
The number 7 becomes the next digit in our result. 
Result so far: 115582.17
If we subtract 1827 from 1990, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 11:
1630 divided by 261 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 115582.176
Subtracting 1566 from 1630 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
If we divide 640 by 261, we get 2 and a remainder of 118.
Use 2 as the next digit of our solution. 
Result so far: 115582.1762
Subtract 522 from 640 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 13:
1180 divided by 261 is 4 with a remainder of 136.
The number 4 becomes the next digit in our result. 
Result so far: 115582.17624
Subtracting 1044 from 1180 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 14:
The number 261 fits into 1360 5 times, leaving a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 115582.176245
Subtract 1305 from 1360 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 15:
When dividing 550 by 261, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 115582.1762452
Deduct 522 from 550 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
261 can be fit into 280 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 115582.17624521
Deduct 261 from 280 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 115582.17624521 with a remainder of 1.9e-08.
