We look at the division of 697543 by 89 
The aim is to understand the frequency of 89 in 697543.

On to step 1:
6 divided by 89 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 89

Let's proceed to step 2:
If we divide 69 by 89, we get 0 and a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Grab the next digit (7) from the dividend, add it to 69, then carry on: 697 / 89

Step 3:
If we divide 697 by 89, we get 7 and a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 623 away from 697, we end up with 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 89

Let's proceed to step 4:
The number 89 fits into 745 8 times, leaving a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 712 from 745 and we're left with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 89

Step 5:
89 goes into 334 3 times with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 783.0
If we take 267 away from 334, we end up with 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 89

Step 6:
The number 89 fits into 673 7 times, leaving a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 7837.0
Subtract 623 from 673 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
When dividing 500 by 89, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 7837.5
The remainder is 55 after subtracting 445 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 8:
89 goes into 550 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 7837.56
The remainder is 16 after subtracting 534 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 89 is 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 7837.561
Subtract 89 from 160 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
89 can be fit into 710 7 times, resulting in a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 7837.5617
Deduct 623 from 710 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 11:
89 can be fit into 870 9 times, resulting in a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 7837.56179
The remainder is 69 after subtracting 801 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 12:
89 goes into 690 7 times with a remainder of 67.
The next digit of our result is 7. 
Result so far: 7837.561797
Deduct 623 from 690 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 13:
89 can be fit into 670 7 times, resulting in a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 7837.5617977
Deduct 623 from 670 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Our division results in 7837.5617977 with a remaining 4.7e-07.
