Let's divide 90942985 by 261
The aim is to understand the frequency of 261 in 90942985.

Step 1:
261 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 261

Going ahead to step 2:
261 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 261

Let's proceed to step 3:
If we divide 909 by 261, we get 3 and a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 126 after subtracting 783 from 909.
Append the next digit (4) from the dividend to 126 and continue with: 1264 / 261

Advancing to step 4:
The number 261 fits into 1264 4 times, leaving a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 1044 from 1264, we get 220.
Fetch the next digit (2) from the dividend, attach it to 220 and continue: 2202 / 261

Going ahead to step 5:
When dividing 2202 by 261, we get 8 with a remainder of 114.
Write down 8 as next digit of the result. 
Result so far: 348.0
If we subtract 2088 from 2202, we get 114.
Fetch the next digit (9) from the dividend, attach it to 114 and continue: 1149 / 261

Going ahead to step 6:
261 can be fit into 1149 4 times, resulting in a remainder of 105.
The number 4 becomes the next digit in our result. 
Result so far: 3484.0
Subtracting 1044 from 1149 leaves us with 105.
Append the next digit (8) from the dividend to 105 and continue with: 1058 / 261

Step 7:
If we divide 1058 by 261, we get 4 and a remainder of 14.
The next digit of our result is 4. 
Result so far: 34844.0
If we take 1044 away from 1058, we end up with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 261

Advancing to step 8:
The number 261 fits into 145 0 times, leaving a remainder of 145.
Put 0 as the next digit of the answer. 
Result so far: 348440.0
If we take 0 away from 145, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 9:
261 can be fit into 1450 5 times, resulting in a remainder of 145.
Record the quotient 5 as the next digit in the result. 
Result so far: 348440.5
Subtracting 1305 from 1450 leaves us with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 10:
261 can be fit into 1450 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 348440.55
If we take 1305 away from 1450, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Our division results in 348440.55 with a remaining 0.145.
