Let's divide 28194248 by 661
The aim is to understand the frequency of 661 in 28194248.

Advancing to step 1:
The number 661 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 661

Moving on to step 2:
The number 661 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 661

Advancing to step 3:
If we divide 281 by 661, we get 0 and a remainder of 281.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 281, we get 281.
Bring next digit (9) of the dividend behind the 281 and repeat the process: 2819 / 661

Step 4:
If we divide 2819 by 661, we get 4 and a remainder of 175.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 2644 from 2819, we get 175.
Include the next digit (4) from the dividend after 175, then repeat: 1754 / 661

Going ahead to step 5:
The number 661 fits into 1754 2 times, leaving a remainder of 432.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 1322 from 1754 and we're left with 432.
Fetch the next digit (2) from the dividend, attach it to 432 and continue: 4322 / 661

Going ahead to step 6:
When dividing 4322 by 661, we get 6 with a remainder of 356.
Put 6 as the next digit of the answer. 
Result so far: 426.0
The remainder is 356 after subtracting 3966 from 4322.
Include the next digit (4) from the dividend after 356, then repeat: 3564 / 661

Advancing to step 7:
When dividing 3564 by 661, we get 5 with a remainder of 259.
Write down 5 as next digit of the result. 
Result so far: 4265.0
If we take 3305 away from 3564, we end up with 259.
Fetch the next digit (8) from the dividend, attach it to 259 and continue: 2598 / 661

Step 8:
When dividing 2598 by 661, we get 3 with a remainder of 615.
The next digit of our result is 3. 
Result so far: 42653.0
Subtracting 1983 from 2598 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Going ahead to step 9:
661 can be fit into 6150 9 times, resulting in a remainder of 201.
The next digit of our result is 9. 
Result so far: 42653.9
If we subtract 5949 from 6150, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 10:
If we divide 2010 by 661, we get 3 and a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 42653.93
Subtracting 1983 from 2010 leaves us 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 11:
The number 661 fits into 270 0 times, leaving a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 42653.93
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 12:
When dividing 2700 by 661, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 42653.9304
The remainder is 56 after subtracting 2644 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
If we divide 560 by 661, we get 0 and a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 42653.9304
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 14:
When dividing 5600 by 661, we get 8 with a remainder of 312.
The number 8 becomes the next digit in our result. 
Result so far: 42653.930408
Subtract 5288 from 5600 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 15:
When dividing 3120 by 661, we get 4 with a remainder of 476.
Write down 4 as next digit of the result. 
Result so far: 42653.9304084
The remainder is 476 after subtracting 2644 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 16:
The number 661 fits into 4760 7 times, leaving a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 42653.93040847
Subtracting 4627 from 4760 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Our division results in 42653.93040847 with a remaining 1.33e-07.
