1579494 ÷ 690 
The aim is to understand the frequency of 690 in 1579494.

Advancing to step 1:
690 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 690

Going ahead to step 2:
If we divide 15 by 690, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 690

Step 3:
690 can be fit into 157 0 times, resulting in a remainder of 157.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 157 and we're left with 157.
Include the next digit (9) from the dividend after 157, then repeat: 1579 / 690

Step 4:
When dividing 1579 by 690, we get 2 with a remainder of 199.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 199 after subtracting 1380 from 1579.
Bring next digit (4) of the dividend behind the 199 and repeat the process: 1994 / 690

Let's proceed to step 5:
690 goes into 1994 2 times with a remainder of 614.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 1380 from 1994, we get 614.
Take the next digit (9) from the dividend and append it to 614, then repeat: 6149 / 690

Step 6:
690 goes into 6149 8 times with a remainder of 629.
Write down 8 as next digit of the result. 
Result so far: 228.0
Subtract 5520 from 6149 to get 629.
Grab the next digit (4) from the dividend, add it to 629, then carry on: 6294 / 690

Advancing to step 7:
The number 690 fits into 6294 9 times, leaving a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 2289.0
Subtract 6210 from 6294 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 8:
690 goes into 840 1 times with a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 2289.1
Subtract 690 from 840 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.

Step 9:
The number 690 fits into 1500 2 times, leaving a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 2289.12
The remainder is 120 after subtracting 1380 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 10:
If we divide 1200 by 690, we get 1 and a remainder of 510.
Put 1 as the next digit of the answer. 
Result so far: 2289.121
Deduct 690 from 1200 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 11:
The number 690 fits into 5100 7 times, leaving a remainder of 270.
Put 7 as the next digit of the answer. 
Result so far: 2289.1217
Subtracting 4830 from 5100 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 12:
If we divide 2700 by 690, we get 3 and a remainder of 630.
Put 3 as the next digit of the answer. 
Result so far: 2289.12173
If we subtract 2070 from 2700, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 13:
690 goes into 6300 9 times with a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 2289.121739
The remainder is 90 after subtracting 6210 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 14:
If we divide 900 by 690, we get 1 and a remainder of 210.
Put 1 as the next digit of the answer. 
Result so far: 2289.1217391
Subtracting 690 from 900 leaves us 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.

Going ahead to step 15:
690 goes into 2100 3 times with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 2289.12173913
Subtracting 2070 from 2100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 2289.12173913 and a remainder of 3e-08.
