We're dividing 2190149 by 690 
The aim is to understand the frequency of 690 in 2190149.

Step 1:
690 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 690

Step 2:
690 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 690

Going ahead to step 3:
When dividing 219 by 690, we get 0 with a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Include the next digit (0) from the dividend after 219, then repeat: 2190 / 690

Let's proceed to step 4:
690 goes into 2190 3 times with a remainder of 120.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2070 from 2190, we get 120.
Grab the next digit (1) from the dividend, add it to 120, then carry on: 1201 / 690

Advancing to step 5:
If we divide 1201 by 690, we get 1 and a remainder of 511.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 690 away from 1201, we end up with 511.
Bring next digit (4) of the dividend behind the 511 and repeat the process: 5114 / 690

Let's proceed to step 6:
The number 690 fits into 5114 7 times, leaving a remainder of 284.
Put 7 as the next digit of the answer. 
Result so far: 317.0
Subtracting 4830 from 5114 leaves us with 284.
Bring next digit (9) of the dividend behind the 284 and repeat the process: 2849 / 690

Step 7:
690 goes into 2849 4 times with a remainder of 89.
The number 4 becomes the next digit in our result. 
Result so far: 3174.0
Subtracting 2760 from 2849 leaves us with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 8:
890 divided by 690 is 1 with a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 3174.1
The remainder is 200 after subtracting 690 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 9:
If we divide 2000 by 690, we get 2 and a remainder of 620.
The number 2 becomes the next digit in our result. 
Result so far: 3174.12
Deduct 1380 from 2000 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 10:
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: 3174.128
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.

Advancing to step 11:
When dividing 6800 by 690, we get 9 with a remainder of 590.
The number 9 becomes the next digit in our result. 
Result so far: 3174.1289
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.

On to step 12:
690 can be fit into 5900 8 times, resulting in a remainder of 380.
Write down 8 as next digit of the result. 
Result so far: 3174.12898
If we subtract 5520 from 5900, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 13:
690 goes into 3800 5 times with a remainder of 350.
The next digit of our result is 5. 
Result so far: 3174.128985
The remainder is 350 after subtracting 3450 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 14:
If we divide 3500 by 690, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3174.1289855
Deduct 3450 from 3500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 3174.1289855 with a balance of 5e-07.
