Let's divide 91516607 by 89
The aim is to understand the frequency of 89 in 91516607.

Advancing to step 1:
9 divided by 89 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 89

Advancing to step 2:
89 can be fit into 91 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 89 from 91.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 89

Step 3:
The number 89 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 89

On to step 4:
If we divide 251 by 89, we get 2 and a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtracting 178 from 251 leaves us with 73.
Append the next digit (6) from the dividend to 73 and continue with: 736 / 89

Going ahead to step 5:
When dividing 736 by 89, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 1028.0
Subtracting 712 from 736 leaves us with 24.
Bring next digit (6) of the dividend behind the 24 and repeat the process: 246 / 89

Moving on to step 6:
When dividing 246 by 89, we get 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 10282.0
If we subtract 178 from 246, we get 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 89

Let's proceed to step 7:
If we divide 680 by 89, we get 7 and a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 102827.0
The remainder is 57 after subtracting 623 from 680.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 89

Step 8:
When dividing 577 by 89, we get 6 with a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 1028276.0
If we subtract 534 from 577, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
If we divide 430 by 89, we get 4 and a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 1028276.4
If we take 356 away from 430, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
89 can be fit into 740 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1028276.48
Subtract 712 from 740 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
89 goes into 280 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 1028276.483
If we take 267 away from 280, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
If we divide 130 by 89, we get 1 and a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1028276.4831
If we subtract 89 from 130, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 13:
When dividing 410 by 89, we get 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 1028276.48314
If we take 356 away from 410, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
If we divide 540 by 89, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 1028276.483146
The remainder is 6 after subtracting 534 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 15:
89 can be fit into 60 0 times, resulting in a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1028276.483146
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 16:
600 divided by 89 is 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 1028276.48314606
The remainder is 66 after subtracting 534 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 1028276.48314606, with a leftover of 6.6e-08.
