13962352 ÷ 690 
The aim is to understand the frequency of 690 in 13962352.

Step 1:
690 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 690

Let's proceed to step 2:
690 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 690

Step 3:
The number 690 fits into 139 0 times, leaving a remainder of 139.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 139, we end up with 139.
Take the next digit (6) from the dividend and append it to 139, then repeat: 1396 / 690

On to step 4:
690 can be fit into 1396 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 16 after subtracting 1380 from 1396.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 690

Step 5:
690 can be fit into 162 0 times, resulting in a remainder of 162.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 162, we end up with 162.
Bring next digit (3) of the dividend behind the 162 and repeat the process: 1623 / 690

Going ahead to step 6:
If we divide 1623 by 690, we get 2 and a remainder of 243.
The next digit of our result is 2. 
Result so far: 202.0
The remainder is 243 after subtracting 1380 from 1623.
Take the next digit (5) from the dividend and append it to 243, then repeat: 2435 / 690

Let's proceed to step 7:
690 goes into 2435 3 times with a remainder of 365.
The number 3 becomes the next digit in our result. 
Result so far: 2023.0
Subtract 2070 from 2435 to get 365.
Bring next digit (2) of the dividend behind the 365 and repeat the process: 3652 / 690

On to step 8:
690 goes into 3652 5 times with a remainder of 202.
Write down 5 as next digit of the result. 
Result so far: 20235.0
If we take 3450 away from 3652, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 9:
2020 divided by 690 is 2 with a remainder of 640.
The next digit of our result is 2. 
Result so far: 20235.2
The remainder is 640 after subtracting 1380 from 2020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 10:
If we divide 6400 by 690, we get 9 and a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 20235.29
If we take 6210 away from 6400, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 11:
1900 divided by 690 is 2 with a remainder of 520.
The number 2 becomes the next digit in our result. 
Result so far: 20235.292
Subtracting 1380 from 1900 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 12:
If we divide 5200 by 690, we get 7 and a remainder of 370.
The number 7 becomes the next digit in our result. 
Result so far: 20235.2927
The remainder is 370 after subtracting 4830 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 13:
690 goes into 3700 5 times with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 20235.29275
If we take 3450 away from 3700, we end up 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.

Let's proceed to step 14:
2500 divided by 690 is 3 with a remainder of 430.
The number 3 becomes the next digit in our result. 
Result so far: 20235.292753
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.

Advancing to step 15:
When dividing 4300 by 690, we get 6 with a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 20235.2927536
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.

Let's proceed to step 16:
When dividing 1600 by 690, we get 2 with a remainder of 220.
Use 2 as the next digit of our solution. 
Result so far: 20235.29275362
Deduct 1380 from 1600 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 20235.29275362 and a remainder of 2.2e-07.
