Let's divide 17940177 by 261
The aim is to understand the frequency of 261 in 17940177.

Moving on to step 1:
If we divide 1 by 261, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 261

Let's proceed to step 2:
When dividing 17 by 261, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 261

On to step 3:
261 goes into 179 0 times with a remainder of 179.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 179, we get 179.
Fetch the next digit (4) from the dividend, attach it to 179 and continue: 1794 / 261

Step 4:
The number 261 fits into 1794 6 times, leaving a remainder of 228.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 1566 from 1794 and we're left with 228.
Fetch the next digit (0) from the dividend, attach it to 228 and continue: 2280 / 261

Moving on to step 5:
The number 261 fits into 2280 8 times, leaving a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Deduct 2088 from 2280 and we're left with 192.
Grab the next digit (1) from the dividend, add it to 192, then carry on: 1921 / 261

On to step 6:
The number 261 fits into 1921 7 times, leaving a remainder of 94.
The next digit of our result is 7. 
Result so far: 687.0
Deduct 1827 from 1921 and we're left with 94.
Take the next digit (7) from the dividend and append it to 94, then repeat: 947 / 261

On to step 7:
261 goes into 947 3 times with a remainder of 164.
The number 3 becomes the next digit in our result. 
Result so far: 6873.0
Subtract 783 from 947 to get 164.
Bring next digit (7) of the dividend behind the 164 and repeat the process: 1647 / 261

Going ahead to step 8:
261 can be fit into 1647 6 times, resulting in a remainder of 81.
The next digit of our result is 6. 
Result so far: 68736.0
Subtracting 1566 from 1647 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
The number 261 fits into 810 3 times, leaving a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 68736.3
Deduct 783 from 810 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 10:
270 divided by 261 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 68736.31
Subtracting 261 from 270 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
When dividing 90 by 261, we get 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 68736.31
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
The number 261 fits into 900 3 times, leaving a remainder of 117.
Record the quotient 3 as the next digit in the result. 
Result so far: 68736.3103
Subtract 783 from 900 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 13:
261 can be fit into 1170 4 times, resulting in a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 68736.31034
Subtract 1044 from 1170 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 14:
If we divide 1260 by 261, we get 4 and a remainder of 216.
Write down 4 as next digit of the result. 
Result so far: 68736.310344
If we take 1044 away from 1260, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

The final outcome is 68736.310344, with a leftover of 2.16e-05.
