18703935 divided by 89 
The aim is to understand the frequency of 89 in 18703935.

Going ahead to step 1:
The number 89 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 89

On to step 2:
89 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 89

On to step 3:
89 can be fit into 187 2 times, resulting in a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 9 after subtracting 178 from 187.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 89

Advancing to step 4:
If we divide 90 by 89, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
Deduct 89 from 90 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 89

Advancing to step 5:
If we divide 13 by 89, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 89

Advancing to step 6:
When dividing 139 by 89, we get 1 with a remainder of 50.
Write down 1 as next digit of the result. 
Result so far: 2101.0
Subtracting 89 from 139 leaves us with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 89

On to step 7:
89 can be fit into 503 5 times, resulting in a remainder of 58.
Use 5 as the next digit of our solution. 
Result so far: 21015.0
The remainder is 58 after subtracting 445 from 503.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 89

On to step 8:
When dividing 585 by 89, we get 6 with a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 210156.0
If we subtract 534 from 585, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
The number 89 fits into 510 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 210156.5
Subtract 445 from 510 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 10:
When dividing 650 by 89, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 210156.57
Subtracting 623 from 650 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
89 can be fit into 270 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 210156.573
The remainder is 3 after subtracting 267 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
The number 89 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 210156.573
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
The number 89 fits into 300 3 times, leaving a remainder of 33.
The next digit of our result is 3. 
Result so far: 210156.57303
If we take 267 away from 300, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 14:
89 goes into 330 3 times with a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 210156.573033
If we subtract 267 from 330, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final result is 210156.573033 with a remainder of 6.3e-06.
