Let's divide 35361609 by 690
The aim is to understand the frequency of 690 in 35361609.

Step 1:
690 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 690

Moving on to step 2:
690 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 690

Going ahead to step 3:
If we divide 353 by 690, we get 0 and a remainder of 353.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 353, we get 353.
Include the next digit (6) from the dividend after 353, then repeat: 3536 / 690

Moving on to step 4:
When dividing 3536 by 690, we get 5 with a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 3450 away from 3536, we end up with 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 690

Advancing to step 5:
When dividing 861 by 690, we get 1 with a remainder of 171.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 690 from 861, we get 171.
Fetch the next digit (6) from the dividend, attach it to 171 and continue: 1716 / 690

Step 6:
The number 690 fits into 1716 2 times, leaving a remainder of 336.
Record the quotient 2 as the next digit in the result. 
Result so far: 512.0
The remainder is 336 after subtracting 1380 from 1716.
Fetch the next digit (0) from the dividend, attach it to 336 and continue: 3360 / 690

Let's proceed to step 7:
690 goes into 3360 4 times with a remainder of 600.
Record the quotient 4 as the next digit in the result. 
Result so far: 5124.0
Deduct 2760 from 3360 and we're left with 600.
Bring next digit (9) of the dividend behind the 600 and repeat the process: 6009 / 690

Let's proceed to step 8:
If we divide 6009 by 690, we get 8 and a remainder of 489.
Use 8 as the next digit of our solution. 
Result so far: 51248.0
Subtract 5520 from 6009 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Moving on to step 9:
If we divide 4890 by 690, we get 7 and a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 51248.7
Subtract 4830 from 4890 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
600 divided by 690 is 0 with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 51248.7
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 11:
690 goes into 6000 8 times with a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 51248.708
Subtracting 5520 from 6000 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 12:
690 goes into 4800 6 times with a remainder of 660.
Record the quotient 6 as the next digit in the result. 
Result so far: 51248.7086
Subtract 4140 from 4800 to get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 13:
690 goes into 6600 9 times with a remainder of 390.
Write down 9 as next digit of the result. 
Result so far: 51248.70869
If we take 6210 away from 6600, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 14:
690 goes into 3900 5 times with a remainder of 450.
Record the quotient 5 as the next digit in the result. 
Result so far: 51248.708695
Subtracting 3450 from 3900 leaves us with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 15:
690 goes into 4500 6 times with a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 51248.7086956
Deduct 4140 from 4500 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 16:
If we divide 3600 by 690, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 51248.70869565
Subtract 3450 from 3600 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

The final result is 51248.70869565 with a remainder of 1.5e-07.
