We're dividing 11669861 by 281 
The aim is to understand the frequency of 281 in 11669861.

Going ahead to step 1:
The number 281 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 281

Moving on to step 2:
The number 281 fits into 11 0 times, leaving a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 281

Let's proceed to step 3:
When dividing 116 by 281, we get 0 with a remainder of 116.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 116 leaves us with 116.
Grab the next digit (6) from the dividend, add it to 116, then carry on: 1166 / 281

Going ahead to step 4:
The number 281 fits into 1166 4 times, leaving a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 1124 from 1166 leaves us with 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 281

Advancing to step 5:
If we divide 429 by 281, we get 1 and a remainder of 148.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 281 from 429 leaves us with 148.
Grab the next digit (8) from the dividend, add it to 148, then carry on: 1488 / 281

Moving on to step 6:
When dividing 1488 by 281, we get 5 with a remainder of 83.
Use 5 as the next digit of our solution. 
Result so far: 415.0
If we subtract 1405 from 1488, we get 83.
Append the next digit (6) from the dividend to 83 and continue with: 836 / 281

Step 7:
836 divided by 281 is 2 with a remainder of 274.
Put 2 as the next digit of the answer. 
Result so far: 4152.0
The remainder is 274 after subtracting 562 from 836.
Bring next digit (1) of the dividend behind the 274 and repeat the process: 2741 / 281

Moving on to step 8:
281 goes into 2741 9 times with a remainder of 212.
Record the quotient 9 as the next digit in the result. 
Result so far: 41529.0
Subtract 2529 from 2741 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 9:
When dividing 2120 by 281, we get 7 with a remainder of 153.
Use 7 as the next digit of our solution. 
Result so far: 41529.7
Deduct 1967 from 2120 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 10:
When dividing 1530 by 281, we get 5 with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 41529.75
Subtracting 1405 from 1530 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
281 can be fit into 1250 4 times, resulting in a remainder of 126.
Put 4 as the next digit of the answer. 
Result so far: 41529.754
If we subtract 1124 from 1250, we 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.

Step 12:
The number 281 fits into 1260 4 times, leaving a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 41529.7544
The remainder is 136 after subtracting 1124 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 41529.7544, with a leftover of 0.00136.
