We look at the division of 3548041 by 281 
The aim is to understand the frequency of 281 in 3548041.

On to step 1:
If we divide 3 by 281, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 281

Moving on to step 2:
281 goes into 35 0 times with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Include the next digit (4) from the dividend after 35, then repeat: 354 / 281

Moving on to step 3:
281 can be fit into 354 1 times, resulting in a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 281 away from 354, we end up with 73.
Grab the next digit (8) from the dividend, add it to 73, then carry on: 738 / 281

Advancing to step 4:
When dividing 738 by 281, we get 2 with a remainder of 176.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 176 after subtracting 562 from 738.
Fetch the next digit (0) from the dividend, attach it to 176 and continue: 1760 / 281

Moving on to step 5:
281 goes into 1760 6 times with a remainder of 74.
The next digit of our result is 6. 
Result so far: 126.0
Subtracting 1686 from 1760 leaves us with 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 281

On to step 6:
744 divided by 281 is 2 with a remainder of 182.
The next digit of our result is 2. 
Result so far: 1262.0
If we take 562 away from 744, we end up with 182.
Include the next digit (1) from the dividend after 182, then repeat: 1821 / 281

Moving on to step 7:
The number 281 fits into 1821 6 times, leaving a remainder of 135.
Put 6 as the next digit of the answer. 
Result so far: 12626.0
Subtracting 1686 from 1821 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 8:
281 goes into 1350 4 times with a remainder of 226.
Record the quotient 4 as the next digit in the result. 
Result so far: 12626.4
If we take 1124 away from 1350, we end up 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.

Going ahead to step 9:
2260 divided by 281 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 12626.48
The remainder is 12 after subtracting 2248 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
120 divided by 281 is 0 with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 12626.48
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
281 goes into 1200 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 12626.4804
Deduct 1124 from 1200 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 12:
The number 281 fits into 760 2 times, leaving a remainder of 198.
Put 2 as the next digit of the answer. 
Result so far: 12626.48042
Subtracting 562 from 760 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 13:
The number 281 fits into 1980 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 12626.480427
If we subtract 1967 from 1980, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 14:
The number 281 fits into 130 0 times, leaving a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 12626.480427
If we take 0 away from 130, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 15:
1300 divided by 281 is 4 with a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 12626.48042704
The remainder is 176 after subtracting 1124 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The quotient of the division is 12626.48042704, and the remainder is 1.76e-07.
