We look at the division of 45515993 by 441 
The aim is to understand the frequency of 441 in 45515993.

Moving on to step 1:
If we divide 4 by 441, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 441

Going ahead to step 2:
If we divide 45 by 441, we get 0 and a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 441

Advancing to step 3:
441 goes into 455 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 441 away from 455, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 441

On to step 4:
When dividing 141 by 441, we get 0 with a remainder of 141.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 141 to get 141.
Fetch the next digit (5) from the dividend, attach it to 141 and continue: 1415 / 441

Let's proceed to step 5:
The number 441 fits into 1415 3 times, leaving a remainder of 92.
The next digit of our result is 3. 
Result so far: 103.0
If we take 1323 away from 1415, we end up with 92.
Take the next digit (9) from the dividend and append it to 92, then repeat: 929 / 441

Advancing to step 6:
If we divide 929 by 441, we get 2 and a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 1032.0
Subtract 882 from 929 to get 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 441

Moving on to step 7:
479 divided by 441 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 10321.0
If we take 441 away from 479, we end up with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 441

On to step 8:
The number 441 fits into 383 0 times, leaving a remainder of 383.
Write down 0 as next digit of the result. 
Result so far: 103210.0
Subtract 0 from 383 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

On to step 9:
The number 441 fits into 3830 8 times, leaving a remainder of 302.
The next digit of our result is 8. 
Result so far: 103210.8
If we subtract 3528 from 3830, we get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 10:
441 can be fit into 3020 6 times, resulting in a remainder of 374.
The number 6 becomes the next digit in our result. 
Result so far: 103210.86
If we subtract 2646 from 3020, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 11:
3740 divided by 441 is 8 with a remainder of 212.
The number 8 becomes the next digit in our result. 
Result so far: 103210.868
The remainder is 212 after subtracting 3528 from 3740.
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 12:
The number 441 fits into 2120 4 times, leaving a remainder of 356.
Put 4 as the next digit of the answer. 
Result so far: 103210.8684
The remainder is 356 after subtracting 1764 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 13:
441 goes into 3560 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 103210.86848
If we subtract 3528 from 3560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
320 divided by 441 is 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 103210.86848
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
The number 441 fits into 3200 7 times, leaving a remainder of 113.
Record the quotient 7 as the next digit in the result. 
Result so far: 103210.8684807
Subtract 3087 from 3200 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 16:
When dividing 1130 by 441, we get 2 with a remainder of 248.
The next digit of our result is 2. 
Result so far: 103210.86848072
The remainder is 248 after subtracting 882 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The quotient of the division is 103210.86848072, and the remainder is 2.48e-07.
