31609375 divided by 69 
The aim is to understand the frequency of 69 in 31609375.

Let's proceed to step 1:
The number 69 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 69

Advancing to step 2:
69 can be fit into 31 0 times, resulting in a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 69

Step 3:
The number 69 fits into 316 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 276 from 316 to get 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 69

Let's proceed to step 4:
The number 69 fits into 400 5 times, leaving a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 345 from 400 leaves us with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 69

Let's proceed to step 5:
If we divide 559 by 69, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 458.0
Deduct 552 from 559 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 69

On to step 6:
When dividing 73 by 69, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 4581.0
Subtract 69 from 73 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 69

Let's proceed to step 7:
If we divide 47 by 69, we get 0 and a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 45810.0
Subtracting 0 from 47 leaves us with 47.
Append the next digit (5) from the dividend to 47 and continue with: 475 / 69

Going ahead to step 8:
When dividing 475 by 69, we get 6 with a remainder of 61.
The next digit of our result is 6. 
Result so far: 458106.0
Subtracting 414 from 475 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 9:
The number 69 fits into 610 8 times, leaving a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 458106.8
If we take 552 away from 610, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
69 goes into 580 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 458106.88
If we take 552 away from 580, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 458106.88 with a balance of 0.028.
