We divide 253813 by 69
The aim is to understand the frequency of 69 in 253813.

Advancing to step 1:
When dividing 2 by 69, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 69

Going ahead to step 2:
If we divide 25 by 69, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 69

On to step 3:
253 divided by 69 is 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 207 from 253 leaves us with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 69

Let's proceed to step 4:
69 can be fit into 468 6 times, resulting in a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 414 away from 468, we end up with 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 69

Advancing to step 5:
When dividing 541 by 69, we get 7 with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 367.0
Subtract 483 from 541 to get 58.
Include the next digit (3) from the dividend after 58, then repeat: 583 / 69

Moving on to step 6:
583 divided by 69 is 8 with a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 3678.0
The remainder is 31 after subtracting 552 from 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
310 divided by 69 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 3678.4
Deduct 276 from 310 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
69 can be fit into 340 4 times, resulting in a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 3678.44
Deduct 276 from 340 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 3678.44, and the remainder is 0.064.
