We're dividing 763080 by 89 
The aim is to understand the frequency of 89 in 763080.

Going ahead to step 1:
When dividing 7 by 89, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 89

On to step 2:
89 can be fit into 76 0 times, resulting in a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 89

Moving on to step 3:
The number 89 fits into 763 8 times, leaving a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 712 from 763 leaves us with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 89

On to step 4:
The number 89 fits into 510 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we take 445 away from 510, we end up with 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 89

Step 5:
If we divide 658 by 89, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 857.0
If we subtract 623 from 658, we get 35.
Append the next digit (0) from the dividend to 35 and continue with: 350 / 89

On to step 6:
The number 89 fits into 350 3 times, leaving a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 8573.0
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.

Going ahead to step 7:
89 goes into 830 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 8573.9
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.

Advancing to step 8:
When dividing 290 by 89, we get 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 8573.93
If we subtract 267 from 290, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
230 divided by 89 is 2 with a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 8573.932
Subtracting 178 from 230 leaves us 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 10:
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: 8573.9325
If we subtract 445 from 520, we 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 11:
The number 89 fits into 750 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 8573.93258
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.

Let's proceed to step 12:
When dividing 380 by 89, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8573.932584
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.

Moving on to step 13:
89 can be fit into 240 2 times, resulting in a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 8573.9325842
Subtract 178 from 240 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
When dividing 620 by 89, we get 6 with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 8573.93258426
If we subtract 534 from 620, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 8573.93258426 with a remainder of 8.6e-08.
