5079403 ÷ 690 
The aim is to understand the frequency of 690 in 5079403.

Advancing to step 1:
If we divide 5 by 690, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 690

Let's proceed to step 2:
If we divide 50 by 690, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 690

Going ahead to step 3:
507 divided by 690 is 0 with a remainder of 507.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 507 leaves us with 507.
Fetch the next digit (9) from the dividend, attach it to 507 and continue: 5079 / 690

Advancing to step 4:
If we divide 5079 by 690, we get 7 and a remainder of 249.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 4830 from 5079 and we're left with 249.
Append the next digit (4) from the dividend to 249 and continue with: 2494 / 690

Going ahead to step 5:
690 can be fit into 2494 3 times, resulting in a remainder of 424.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtract 2070 from 2494 to get 424.
Grab the next digit (0) from the dividend, add it to 424, then carry on: 4240 / 690

Advancing to step 6:
4240 divided by 690 is 6 with a remainder of 100.
Put 6 as the next digit of the answer. 
Result so far: 736.0
If we take 4140 away from 4240, we end up with 100.
Grab the next digit (3) from the dividend, add it to 100, then carry on: 1003 / 690

Let's proceed to step 7:
690 goes into 1003 1 times with a remainder of 313.
Put 1 as the next digit of the answer. 
Result so far: 7361.0
The remainder is 313 after subtracting 690 from 1003.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

On to step 8:
When dividing 3130 by 690, we get 4 with a remainder of 370.
Write down 4 as next digit of the result. 
Result so far: 7361.4
Subtract 2760 from 3130 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 9:
3700 divided by 690 is 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 7361.45
Subtracting 3450 from 3700 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
690 can be fit into 2500 3 times, resulting in a remainder of 430.
The number 3 becomes the next digit in our result. 
Result so far: 7361.453
Subtract 2070 from 2500 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 11:
4300 divided by 690 is 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 7361.4536
If we subtract 4140 from 4300, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 12:
690 can be fit into 1600 2 times, resulting in a remainder of 220.
The next digit of our result is 2. 
Result so far: 7361.45362
If we subtract 1380 from 1600, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 13:
When dividing 2200 by 690, we get 3 with a remainder of 130.
The number 3 becomes the next digit in our result. 
Result so far: 7361.453623
Subtracting 2070 from 2200 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 14:
690 goes into 1300 1 times with a remainder of 610.
Put 1 as the next digit of the answer. 
Result so far: 7361.4536231
Subtract 690 from 1300 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 15:
690 can be fit into 6100 8 times, resulting in a remainder of 580.
Record the quotient 8 as the next digit in the result. 
Result so far: 7361.45362318
If we subtract 5520 from 6100, we get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The final outcome is 7361.45362318, with a leftover of 5.8e-07.
