715813 ÷ 89 
The aim is to understand the frequency of 89 in 715813.

On to step 1:
89 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 89

Let's proceed to step 2:
71 divided by 89 is 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 89

Going ahead to step 3:
The number 89 fits into 715 8 times, leaving a remainder of 3.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 712 from 715, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 89

Going ahead to step 4:
89 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 89

Advancing to step 5:
381 divided by 89 is 4 with a remainder of 25.
The next digit of our result is 4. 
Result so far: 804.0
If we take 356 away from 381, we end up with 25.
Take the next digit (3) from the dividend and append it to 25, then repeat: 253 / 89

Let's proceed to step 6:
The number 89 fits into 253 2 times, leaving a remainder of 75.
The next digit of our result is 2. 
Result so far: 8042.0
If we take 178 away from 253, 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.

Moving on to step 7:
89 goes into 750 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 8042.8
If we take 712 away from 750, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 8:
The number 89 fits into 380 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8042.84
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.

On to step 9:
When dividing 240 by 89, we get 2 with a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 8042.842
Deduct 178 from 240 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
If we divide 620 by 89, we get 6 and a remainder of 86.
The next digit of our result is 6. 
Result so far: 8042.8426
The remainder is 86 after subtracting 534 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 11:
When dividing 860 by 89, we get 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 8042.84269
Subtract 801 from 860 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 12:
The number 89 fits into 590 6 times, leaving a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 8042.842696
Subtract 534 from 590 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
When dividing 560 by 89, we get 6 with a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 8042.8426966
If we take 534 away from 560, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 8042.8426966, with a leftover of 2.6e-07.
