381858 ÷ 89 
The aim is to understand the frequency of 89 in 381858.

Let's proceed to step 1:
89 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 89

Moving on to step 2:
38 divided by 89 is 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 89

Let's proceed to step 3:
89 can be fit into 381 4 times, resulting in a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 356 from 381 to get 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 89

On to step 4:
89 can be fit into 258 2 times, resulting in a remainder of 80.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 178 from 258 to get 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 89

On to step 5:
89 can be fit into 805 9 times, resulting in a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 429.0
Subtract 801 from 805 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 89

Going ahead to step 6:
If we divide 48 by 89, we get 0 and a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 4290.0
If we take 0 away from 48, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
89 goes into 480 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 4290.5
Subtracting 445 from 480 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
The number 89 fits into 350 3 times, leaving a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 4290.53
Subtracting 267 from 350 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 9:
When dividing 830 by 89, we get 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 4290.539
If we subtract 801 from 830, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 10:
89 goes into 290 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 4290.5393
If we take 267 away from 290, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 11:
89 goes into 230 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 4290.53932
If we take 178 away from 230, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
89 goes into 520 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4290.539325
Subtract 445 from 520 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
When dividing 750 by 89, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 4290.5393258
Subtract 712 from 750 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 14:
89 can be fit into 380 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 4290.53932584
If we subtract 356 from 380, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 4290.53932584, with a leftover of 2.4e-08.
