We look at the division of 737888 by 89 
The aim is to understand the frequency of 89 in 737888.

Step 1:
When dividing 7 by 89, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 89

Going ahead to step 2:
89 goes into 73 0 times with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Fetch the next digit (7) from the dividend, attach it to 73 and continue: 737 / 89

Moving on to step 3:
When dividing 737 by 89, we get 8 with a remainder of 25.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 712 from 737 leaves us with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 89

Going ahead to step 4:
89 can be fit into 258 2 times, resulting in a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 178 from 258, we get 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 89

Moving on to step 5:
The number 89 fits into 808 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 829.0
If we take 801 away from 808, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 89

Let's proceed to step 6:
89 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 8290.0
Deduct 0 from 78 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 7:
The number 89 fits into 780 8 times, leaving a remainder of 68.
Use 8 as the next digit of our solution. 
Result so far: 8290.8
If we take 712 away from 780, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
680 divided by 89 is 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 8290.87
If we take 623 away from 680, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
The number 89 fits into 570 6 times, leaving a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 8290.876
Deduct 534 from 570 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
When dividing 360 by 89, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 8290.8764
If we subtract 356 from 360, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
89 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8290.8764
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
If we divide 400 by 89, we get 4 and a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 8290.876404
Subtract 356 from 400 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
440 divided by 89 is 4 with a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 8290.8764044
The remainder is 84 after subtracting 356 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

After the division, we end up with 8290.8764044 and a remainder of 8.4e-07.
