We divide 647398 by 89
The aim is to understand the frequency of 89 in 647398.

Advancing to step 1:
If we divide 6 by 89, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 89

Advancing to step 2:
89 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 89

On to step 3:
If we divide 647 by 89, we get 7 and a remainder of 24.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 24 after subtracting 623 from 647.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 89

Let's proceed to step 4:
When dividing 243 by 89, we get 2 with a remainder of 65.
Write down 2 as next digit of the result. 
Result so far: 72.0
Subtract 178 from 243 to get 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 89

Let's proceed to step 5:
89 can be fit into 659 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 727.0
The remainder is 36 after subtracting 623 from 659.
Include the next digit (8) from the dividend after 36, then repeat: 368 / 89

Moving on to step 6:
If we divide 368 by 89, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 7274.0
The remainder is 12 after subtracting 356 from 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
When dividing 120 by 89, we get 1 with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 7274.1
If we take 89 away from 120, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 8:
If we divide 310 by 89, we get 3 and a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 7274.13
Deduct 267 from 310 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
89 can be fit into 430 4 times, resulting in a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 7274.134
Subtract 356 from 430 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
740 divided by 89 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 7274.1348
If we subtract 712 from 740, we 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.

Step 11:
The number 89 fits into 280 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 7274.13483
If we subtract 267 from 280, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
The number 89 fits into 130 1 times, leaving a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 7274.134831
The remainder is 41 after subtracting 89 from 130.
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:
If we divide 410 by 89, we get 4 and a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 7274.1348314
Subtract 356 from 410 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
89 can be fit into 540 6 times, resulting in a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 7274.13483146
If we subtract 534 from 540, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 7274.13483146, with a leftover of 6e-09.
