We're dividing 36921507 by 690 
The aim is to understand the frequency of 690 in 36921507.

Let's proceed to step 1:
When dividing 3 by 690, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 690

Going ahead to step 2:
690 goes into 36 0 times with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 690

Going ahead to step 3:
If we divide 369 by 690, we get 0 and a remainder of 369.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 369 after subtracting 0 from 369.
Include the next digit (2) from the dividend after 369, then repeat: 3692 / 690

Going ahead to step 4:
690 can be fit into 3692 5 times, resulting in a remainder of 242.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 3450 away from 3692, we end up with 242.
Append the next digit (1) from the dividend to 242 and continue with: 2421 / 690

On to step 5:
690 goes into 2421 3 times with a remainder of 351.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Subtracting 2070 from 2421 leaves us with 351.
Fetch the next digit (5) from the dividend, attach it to 351 and continue: 3515 / 690

Going ahead to step 6:
When dividing 3515 by 690, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 535.0
If we subtract 3450 from 3515, we get 65.
Take the next digit (0) from the dividend and append it to 65, then repeat: 650 / 690

Let's proceed to step 7:
If we divide 650 by 690, we get 0 and a remainder of 650.
Record the quotient 0 as the next digit in the result. 
Result so far: 5350.0
If we subtract 0 from 650, we get 650.
Grab the next digit (7) from the dividend, add it to 650, then carry on: 6507 / 690

Going ahead to step 8:
If we divide 6507 by 690, we get 9 and a remainder of 297.
The number 9 becomes the next digit in our result. 
Result so far: 53509.0
Subtract 6210 from 6507 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 9:
2970 divided by 690 is 4 with a remainder of 210.
Use 4 as the next digit of our solution. 
Result so far: 53509.4
If we take 2760 away from 2970, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
690 goes into 2100 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 53509.43
The remainder is 30 after subtracting 2070 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
If we divide 300 by 690, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 53509.43
If we take 0 away from 300, we end up 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.

On to step 12:
690 goes into 3000 4 times with a remainder of 240.
The next digit of our result is 4. 
Result so far: 53509.4304
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.

Let's proceed to step 13:
690 goes into 2400 3 times with a remainder of 330.
Put 3 as the next digit of the answer. 
Result so far: 53509.43043
Subtract 2070 from 2400 to get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 14:
If we divide 3300 by 690, we get 4 and a remainder of 540.
Use 4 as the next digit of our solution. 
Result so far: 53509.430434
Subtracting 2760 from 3300 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 15:
When dividing 5400 by 690, we get 7 with a remainder of 570.
Use 7 as the next digit of our solution. 
Result so far: 53509.4304347
If we take 4830 away from 5400, we end up with 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 16:
690 goes into 5700 8 times with a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 53509.43043478
Subtracting 5520 from 5700 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

In conclusion, the division gives 53509.43043478 with a balance of 1.8e-07.
