We're dividing 91104249 by 690 
The aim is to understand the frequency of 690 in 91104249.

Advancing to step 1:
When dividing 9 by 690, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 690

Step 2:
91 divided by 690 is 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Bring next digit (1) of the dividend behind the 91 and repeat the process: 911 / 690

Going ahead to step 3:
911 divided by 690 is 1 with a remainder of 221.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 690 away from 911, we end up with 221.
Append the next digit (0) from the dividend to 221 and continue with: 2210 / 690

Step 4:
If we divide 2210 by 690, we get 3 and a remainder of 140.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 140 after subtracting 2070 from 2210.
Append the next digit (4) from the dividend to 140 and continue with: 1404 / 690

Step 5:
When dividing 1404 by 690, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Deduct 1380 from 1404 and we're left with 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 690

Advancing to step 6:
690 can be fit into 242 0 times, resulting in a remainder of 242.
Record the quotient 0 as the next digit in the result. 
Result so far: 1320.0
Subtract 0 from 242 to get 242.
Grab the next digit (4) from the dividend, add it to 242, then carry on: 2424 / 690

On to step 7:
690 can be fit into 2424 3 times, resulting in a remainder of 354.
Use 3 as the next digit of our solution. 
Result so far: 13203.0
If we subtract 2070 from 2424, we get 354.
Take the next digit (9) from the dividend and append it to 354, then repeat: 3549 / 690

Let's proceed to step 8:
690 goes into 3549 5 times with a remainder of 99.
Put 5 as the next digit of the answer. 
Result so far: 132035.0
The remainder is 99 after subtracting 3450 from 3549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Moving on to step 9:
990 divided by 690 is 1 with a remainder of 300.
Record the quotient 1 as the next digit in the result. 
Result so far: 132035.1
Subtracting 690 from 990 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
3000 divided by 690 is 4 with a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 132035.14
Subtracting 2760 from 3000 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
If we divide 2400 by 690, we get 3 and a remainder of 330.
Record the quotient 3 as the next digit in the result. 
Result so far: 132035.143
Deduct 2070 from 2400 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 12:
The number 690 fits into 3300 4 times, leaving a remainder of 540.
Record the quotient 4 as the next digit in the result. 
Result so far: 132035.1434
The remainder is 540 after subtracting 2760 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Let's proceed to step 13:
5400 divided by 690 is 7 with a remainder of 570.
The next digit of our result is 7. 
Result so far: 132035.14347
If we subtract 4830 from 5400, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Let's proceed to step 14:
When dividing 5700 by 690, we get 8 with a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 132035.143478
The remainder is 180 after subtracting 5520 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 15:
The number 690 fits into 1800 2 times, leaving a remainder of 420.
Put 2 as the next digit of the answer. 
Result so far: 132035.1434782
Subtracting 1380 from 1800 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 16:
690 goes into 4200 6 times with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 132035.14347826
Subtracting 4140 from 4200 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 132035.14347826 with a balance of 6e-08.
