89481623 divided by 661 
The aim is to understand the frequency of 661 in 89481623.

Moving on to step 1:
661 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 661

Let's proceed to step 2:
661 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Fetch the next digit (4) from the dividend, attach it to 89 and continue: 894 / 661

Moving on to step 3:
The number 661 fits into 894 1 times, leaving a remainder of 233.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 661 from 894 and we're left with 233.
Fetch the next digit (8) from the dividend, attach it to 233 and continue: 2338 / 661

Step 4:
2338 divided by 661 is 3 with a remainder of 355.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1983 from 2338 leaves us with 355.
Bring next digit (1) of the dividend behind the 355 and repeat the process: 3551 / 661

On to step 5:
The number 661 fits into 3551 5 times, leaving a remainder of 246.
Write down 5 as next digit of the result. 
Result so far: 135.0
Subtract 3305 from 3551 to get 246.
Take the next digit (6) from the dividend and append it to 246, then repeat: 2466 / 661

Going ahead to step 6:
When dividing 2466 by 661, we get 3 with a remainder of 483.
Use 3 as the next digit of our solution. 
Result so far: 1353.0
The remainder is 483 after subtracting 1983 from 2466.
Bring next digit (2) of the dividend behind the 483 and repeat the process: 4832 / 661

Moving on to step 7:
4832 divided by 661 is 7 with a remainder of 205.
The number 7 becomes the next digit in our result. 
Result so far: 13537.0
If we subtract 4627 from 4832, we get 205.
Fetch the next digit (3) from the dividend, attach it to 205 and continue: 2053 / 661

Let's proceed to step 8:
661 can be fit into 2053 3 times, resulting in a remainder of 70.
The next digit of our result is 3. 
Result so far: 135373.0
Deduct 1983 from 2053 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
When dividing 700 by 661, we get 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 135373.1
If we subtract 661 from 700, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
661 can be fit into 390 0 times, resulting in a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 135373.1
If we subtract 0 from 390, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 11:
3900 divided by 661 is 5 with a remainder of 595.
Use 5 as the next digit of our solution. 
Result so far: 135373.105
Subtract 3305 from 3900 to get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

Let's proceed to step 12:
661 can be fit into 5950 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 135373.1059
The remainder is 1 after subtracting 5949 from 5950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
When dividing 10 by 661, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 135373.1059
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
When dividing 100 by 661, we get 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 135373.1059
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 135373.1059 and a remainder of 1e-05.
