We divide 89605921 by 481
The aim is to understand the frequency of 481 in 89605921.

Going ahead to step 1:
When dividing 8 by 481, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 481

Moving on to step 2:
If we divide 89 by 481, we get 0 and a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (6) from the dividend after 89, then repeat: 896 / 481

Advancing to step 3:
481 can be fit into 896 1 times, resulting in a remainder of 415.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 481 from 896 leaves us with 415.
Append the next digit (0) from the dividend to 415 and continue with: 4150 / 481

Step 4:
When dividing 4150 by 481, we get 8 with a remainder of 302.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 3848 from 4150 leaves us with 302.
Append the next digit (5) from the dividend to 302 and continue with: 3025 / 481

Let's proceed to step 5:
3025 divided by 481 is 6 with a remainder of 139.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
If we subtract 2886 from 3025, we get 139.
Append the next digit (9) from the dividend to 139 and continue with: 1399 / 481

On to step 6:
1399 divided by 481 is 2 with a remainder of 437.
Record the quotient 2 as the next digit in the result. 
Result so far: 1862.0
Deduct 962 from 1399 and we're left with 437.
Grab the next digit (2) from the dividend, add it to 437, then carry on: 4372 / 481

Advancing to step 7:
When dividing 4372 by 481, we get 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 18629.0
The remainder is 43 after subtracting 4329 from 4372.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 481

Step 8:
431 divided by 481 is 0 with a remainder of 431.
The next digit of our result is 0. 
Result so far: 186290.0
If we take 0 away from 431, we end up with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Let's proceed to step 9:
The number 481 fits into 4310 8 times, leaving a remainder of 462.
Put 8 as the next digit of the answer. 
Result so far: 186290.8
If we take 3848 away from 4310, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Going ahead to step 10:
4620 divided by 481 is 9 with a remainder of 291.
Write down 9 as next digit of the result. 
Result so far: 186290.89
If we take 4329 away from 4620, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 11:
When dividing 2910 by 481, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 186290.896
The remainder is 24 after subtracting 2886 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
When dividing 240 by 481, we get 0 with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 186290.896
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 13:
481 can be fit into 2400 4 times, resulting in a remainder of 476.
The next digit of our result is 4. 
Result so far: 186290.89604
If we subtract 1924 from 2400, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 14:
481 goes into 4760 9 times with a remainder of 431.
Write down 9 as next digit of the result. 
Result so far: 186290.896049
If we subtract 4329 from 4760, we get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Let's proceed to step 15:
481 goes into 4310 8 times with a remainder of 462.
Record the quotient 8 as the next digit in the result. 
Result so far: 186290.8960498
If we subtract 3848 from 4310, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Let's proceed to step 16:
The number 481 fits into 4620 9 times, leaving a remainder of 291.
Write down 9 as next digit of the result. 
Result so far: 186290.89604989
If we take 4329 away from 4620, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

After the division, we end up with 186290.89604989 and a remainder of 2.91e-07.
