We divide 87021675 by 441
The aim is to understand the frequency of 441 in 87021675.

On to step 1:
441 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 441

Step 2:
If we divide 87 by 441, we get 0 and a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 441

Let's proceed to step 3:
441 goes into 870 1 times with a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 441 from 870 leaves us with 429.
Include the next digit (2) from the dividend after 429, then repeat: 4292 / 441

Advancing to step 4:
4292 divided by 441 is 9 with a remainder of 323.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 323 after subtracting 3969 from 4292.
Append the next digit (1) from the dividend to 323 and continue with: 3231 / 441

Advancing to step 5:
3231 divided by 441 is 7 with a remainder of 144.
Use 7 as the next digit of our solution. 
Result so far: 197.0
Deduct 3087 from 3231 and we're left with 144.
Include the next digit (6) from the dividend after 144, then repeat: 1446 / 441

Going ahead to step 6:
1446 divided by 441 is 3 with a remainder of 123.
Record the quotient 3 as the next digit in the result. 
Result so far: 1973.0
Subtract 1323 from 1446 to get 123.
Fetch the next digit (7) from the dividend, attach it to 123 and continue: 1237 / 441

Let's proceed to step 7:
When dividing 1237 by 441, we get 2 with a remainder of 355.
The next digit of our result is 2. 
Result so far: 19732.0
If we take 882 away from 1237, we end up with 355.
Append the next digit (5) from the dividend to 355 and continue with: 3555 / 441

Step 8:
When dividing 3555 by 441, we get 8 with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 197328.0
If we subtract 3528 from 3555, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
The number 441 fits into 270 0 times, leaving a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 197328.0
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
2700 divided by 441 is 6 with a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 197328.06
If we take 2646 away from 2700, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
540 divided by 441 is 1 with a remainder of 99.
Record the quotient 1 as the next digit in the result. 
Result so far: 197328.061
Subtract 441 from 540 to get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 12:
990 divided by 441 is 2 with a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 197328.0612
If we take 882 away from 990, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 13:
1080 divided by 441 is 2 with a remainder of 198.
Record the quotient 2 as the next digit in the result. 
Result so far: 197328.06122
If we take 882 away from 1080, we end up 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.

The quotient of the division is 197328.06122, and the remainder is 0.000198.
