We look at the division of 251920 by 89 
The aim is to understand the frequency of 89 in 251920.

Going ahead to step 1:
2 divided by 89 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 89

Let's proceed to step 2:
If we divide 25 by 89, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 89

Step 3:
251 divided by 89 is 2 with a remainder of 73.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 178 from 251, we get 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 89

Going ahead to step 4:
If we divide 739 by 89, we get 8 and a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 712 from 739 and we're left with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 89

On to step 5:
89 goes into 272 3 times with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 283.0
If we subtract 267 from 272, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 89

Going ahead to step 6:
The number 89 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 2830.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
If we divide 500 by 89, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 2830.5
Subtract 445 from 500 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
550 divided by 89 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 2830.56
Subtracting 534 from 550 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
160 divided by 89 is 1 with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 2830.561
If we subtract 89 from 160, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 10:
710 divided by 89 is 7 with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 2830.5617
Subtracting 623 from 710 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 11:
89 can be fit into 870 9 times, resulting in a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 2830.56179
Subtracting 801 from 870 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 12:
89 can be fit into 690 7 times, resulting in a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 2830.561797
Subtract 623 from 690 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 13:
If we divide 670 by 89, we get 7 and a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 2830.5617977
Deduct 623 from 670 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

In conclusion, the division gives 2830.5617977 with a balance of 4.7e-07.
