Let's divide 90048391 by 445
The aim is to understand the frequency of 445 in 90048391.

Step 1:
The number 445 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 445

On to step 2:
90 divided by 445 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 445

Let's proceed to step 3:
If we divide 900 by 445, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 890 from 900 to get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 445

Going ahead to step 4:
If we divide 104 by 445, we get 0 and a remainder of 104.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 104 to get 104.
Grab the next digit (8) from the dividend, add it to 104, then carry on: 1048 / 445

Step 5:
1048 divided by 445 is 2 with a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 202.0
Subtract 890 from 1048 to get 158.
Append the next digit (3) from the dividend to 158 and continue with: 1583 / 445

Advancing to step 6:
1583 divided by 445 is 3 with a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 2023.0
Subtracting 1335 from 1583 leaves us with 248.
Fetch the next digit (9) from the dividend, attach it to 248 and continue: 2489 / 445

On to step 7:
The number 445 fits into 2489 5 times, leaving a remainder of 264.
The next digit of our result is 5. 
Result so far: 20235.0
Subtracting 2225 from 2489 leaves us with 264.
Fetch the next digit (1) from the dividend, attach it to 264 and continue: 2641 / 445

Let's proceed to step 8:
If we divide 2641 by 445, we get 5 and a remainder of 416.
The number 5 becomes the next digit in our result. 
Result so far: 202355.0
If we subtract 2225 from 2641, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 9:
4160 divided by 445 is 9 with a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 202355.9
Deduct 4005 from 4160 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 10:
If we divide 1550 by 445, we get 3 and a remainder of 215.
The next digit of our result is 3. 
Result so far: 202355.93
If we take 1335 away from 1550, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 11:
2150 divided by 445 is 4 with a remainder of 370.
Record the quotient 4 as the next digit in the result. 
Result so far: 202355.934
The remainder is 370 after subtracting 1780 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 12:
The number 445 fits into 3700 8 times, leaving a remainder of 140.
The next digit of our result is 8. 
Result so far: 202355.9348
The remainder is 140 after subtracting 3560 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
The number 445 fits into 1400 3 times, leaving a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 202355.93483
Subtracting 1335 from 1400 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 14:
445 goes into 650 1 times with a remainder of 205.
Record the quotient 1 as the next digit in the result. 
Result so far: 202355.934831
Subtracting 445 from 650 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 15:
The number 445 fits into 2050 4 times, leaving a remainder of 270.
Record the quotient 4 as the next digit in the result. 
Result so far: 202355.9348314
If we subtract 1780 from 2050, we 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.

Step 16:
If we divide 2700 by 445, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 202355.93483146
The remainder is 30 after subtracting 2670 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 202355.93483146 and a remainder of 3e-08.
