768919 divided by 89 
The aim is to understand the frequency of 89 in 768919.

On to step 1:
89 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 89

Moving on to step 2:
If we divide 76 by 89, we get 0 and a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 89

Step 3:
89 goes into 768 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 712 away from 768, we end up with 56.
Bring next digit (9) of the dividend behind the 56 and repeat the process: 569 / 89

Moving on to step 4:
The number 89 fits into 569 6 times, leaving a remainder of 35.
The next digit of our result is 6. 
Result so far: 86.0
Subtracting 534 from 569 leaves us with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 89

Going ahead to step 5:
When dividing 351 by 89, we get 3 with a remainder of 84.
The number 3 becomes the next digit in our result. 
Result so far: 863.0
If we subtract 267 from 351, we get 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 89

On to step 6:
849 divided by 89 is 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 8639.0
The remainder is 48 after subtracting 801 from 849.
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:
The number 89 fits into 480 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 8639.5
Deduct 445 from 480 and we're left 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.
The number 3 becomes the next digit in our result. 
Result so far: 8639.53
Subtract 267 from 350 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 9:
89 goes into 830 9 times with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 8639.539
Subtracting 801 from 830 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
If we divide 290 by 89, we get 3 and a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 8639.5393
The remainder is 23 after subtracting 267 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
When dividing 230 by 89, we get 2 with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 8639.53932
If we subtract 178 from 230, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
When dividing 520 by 89, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 8639.539325
If we take 445 away from 520, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
750 divided by 89 is 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 8639.5393258
The remainder is 38 after subtracting 712 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
89 goes into 380 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8639.53932584
Deduct 356 from 380 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 8639.53932584 and a remainder of 2.4e-08.
