74431314 divided by 690 
The aim is to understand the frequency of 690 in 74431314.

On to step 1:
7 divided by 690 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 690

Advancing to step 2:
690 goes into 74 0 times with a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 690

On to step 3:
If we divide 744 by 690, we get 1 and a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 54 after subtracting 690 from 744.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 690

Let's proceed to step 4:
543 divided by 690 is 0 with a remainder of 543.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 543 and we're left with 543.
Include the next digit (1) from the dividend after 543, then repeat: 5431 / 690

Let's proceed to step 5:
If we divide 5431 by 690, we get 7 and a remainder of 601.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
The remainder is 601 after subtracting 4830 from 5431.
Fetch the next digit (3) from the dividend, attach it to 601 and continue: 6013 / 690

Let's proceed to step 6:
If we divide 6013 by 690, we get 8 and a remainder of 493.
Record the quotient 8 as the next digit in the result. 
Result so far: 1078.0
If we subtract 5520 from 6013, we get 493.
Append the next digit (1) from the dividend to 493 and continue with: 4931 / 690

Let's proceed to step 7:
4931 divided by 690 is 7 with a remainder of 101.
Use 7 as the next digit of our solution. 
Result so far: 10787.0
If we take 4830 away from 4931, we end up with 101.
Fetch the next digit (4) from the dividend, attach it to 101 and continue: 1014 / 690

Advancing to step 8:
When dividing 1014 by 690, we get 1 with a remainder of 324.
Write down 1 as next digit of the result. 
Result so far: 107871.0
Subtracting 690 from 1014 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Step 9:
The number 690 fits into 3240 4 times, leaving a remainder of 480.
Write down 4 as next digit of the result. 
Result so far: 107871.4
The remainder is 480 after subtracting 2760 from 3240.
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 10:
4800 divided by 690 is 6 with a remainder of 660.
The number 6 becomes the next digit in our result. 
Result so far: 107871.46
Deduct 4140 from 4800 and we're left with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Moving on to step 11:
690 goes into 6600 9 times with a remainder of 390.
Record the quotient 9 as the next digit in the result. 
Result so far: 107871.469
Subtract 6210 from 6600 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 12:
When dividing 3900 by 690, we get 5 with a remainder of 450.
The next digit of our result is 5. 
Result so far: 107871.4695
The remainder is 450 after subtracting 3450 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 13:
The number 690 fits into 4500 6 times, leaving a remainder of 360.
Record the quotient 6 as the next digit in the result. 
Result so far: 107871.46956
If we take 4140 away from 4500, we end up 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.

Step 14:
690 can be fit into 3600 5 times, resulting in a remainder of 150.
Put 5 as the next digit of the answer. 
Result so far: 107871.469565
The remainder is 150 after subtracting 3450 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 15:
690 can be fit into 1500 2 times, resulting in a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 107871.4695652
If we take 1380 away from 1500, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
The number 690 fits into 1200 1 times, leaving a remainder of 510.
Record the quotient 1 as the next digit in the result. 
Result so far: 107871.46956521
Subtracting 690 from 1200 leaves us 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.

The final outcome is 107871.46956521, with a leftover of 5.1e-07.
