We're dividing 88804100 by 690 
The aim is to understand the frequency of 690 in 88804100.

Going ahead to step 1:
When dividing 8 by 690, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 690

Let's proceed to step 2:
690 goes into 88 0 times with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Append the next digit (8) from the dividend to 88 and continue with: 888 / 690

On to step 3:
The number 690 fits into 888 1 times, leaving a remainder of 198.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 690 from 888 to get 198.
Include the next digit (0) from the dividend after 198, then repeat: 1980 / 690

On to step 4:
The number 690 fits into 1980 2 times, leaving a remainder of 600.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 600 after subtracting 1380 from 1980.
Bring next digit (4) of the dividend behind the 600 and repeat the process: 6004 / 690

Moving on to step 5:
The number 690 fits into 6004 8 times, leaving a remainder of 484.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Deduct 5520 from 6004 and we're left with 484.
Fetch the next digit (1) from the dividend, attach it to 484 and continue: 4841 / 690

On to step 6:
690 goes into 4841 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 1287.0
If we take 4830 away from 4841, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 690

Moving on to step 7:
690 can be fit into 110 0 times, resulting in a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 12870.0
Deduct 0 from 110 and we're left with 110.
Grab the next digit (0) from the dividend, add it to 110, then carry on: 1100 / 690

On to step 8:
690 goes into 1100 1 times with a remainder of 410.
The next digit of our result is 1. 
Result so far: 128701.0
Deduct 690 from 1100 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 9:
If we divide 4100 by 690, we get 5 and a remainder of 650.
Record the quotient 5 as the next digit in the result. 
Result so far: 128701.5
Subtract 3450 from 4100 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 10:
690 can be fit into 6500 9 times, resulting in a remainder of 290.
Put 9 as the next digit of the answer. 
Result so far: 128701.59
Subtract 6210 from 6500 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 11:
2900 divided by 690 is 4 with a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 128701.594
If we subtract 2760 from 2900, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 12:
690 goes into 1400 2 times with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 128701.5942
The remainder is 20 after subtracting 1380 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
690 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 128701.5942
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 14:
690 goes into 2000 2 times with a remainder of 620.
Record the quotient 2 as the next digit in the result. 
Result so far: 128701.594202
If we subtract 1380 from 2000, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

On to step 15:
The number 690 fits into 6200 8 times, leaving a remainder of 680.
Record the quotient 8 as the next digit in the result. 
Result so far: 128701.5942028
Subtracting 5520 from 6200 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Let's proceed to step 16:
690 goes into 6800 9 times with a remainder of 590.
The next digit of our result is 9. 
Result so far: 128701.59420289
If we subtract 6210 from 6800, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

The final result is 128701.59420289 with a remainder of 5.9e-07.
