We divide 45375671 by 89
The aim is to understand the frequency of 89 in 45375671.

Advancing to step 1:
89 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 89

On to step 2:
If we divide 45 by 89, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 89

Going ahead to step 3:
If we divide 453 by 89, we get 5 and a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 445 from 453 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 89

Let's proceed to step 4:
89 can be fit into 87 0 times, resulting in a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtract 0 from 87 to get 87.
Append the next digit (5) from the dividend to 87 and continue with: 875 / 89

Moving on to step 5:
89 can be fit into 875 9 times, resulting in a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 509.0
The remainder is 74 after subtracting 801 from 875.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 89

Moving on to step 6:
The number 89 fits into 746 8 times, leaving a remainder of 34.
The next digit of our result is 8. 
Result so far: 5098.0
The remainder is 34 after subtracting 712 from 746.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 89

Moving on to step 7:
The number 89 fits into 347 3 times, leaving a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 50983.0
The remainder is 80 after subtracting 267 from 347.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 89

On to step 8:
89 can be fit into 801 9 times, resulting in a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 509839.0
Subtracting 801 from 801 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 89 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 509839.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 89, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 509839.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 509839.0, with a leftover of 0.0.
