We're dividing 53368286 by 69 
The aim is to understand the frequency of 69 in 53368286.

Let's proceed to step 1:
69 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 69

Going ahead to step 2:
When dividing 53 by 69, we get 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (3) from the dividend, attach it to 53 and continue: 533 / 69

Step 3:
69 can be fit into 533 7 times, resulting in a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 483 from 533 and we're left with 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 69

On to step 4:
69 goes into 506 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Deduct 483 from 506 and we're left with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 69

Moving on to step 5:
When dividing 238 by 69, we get 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 773.0
The remainder is 31 after subtracting 207 from 238.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 69

Let's proceed to step 6:
If we divide 312 by 69, we get 4 and a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 7734.0
If we subtract 276 from 312, we get 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 69

Step 7:
The number 69 fits into 368 5 times, leaving a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 77345.0
Deduct 345 from 368 and we're left with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 69

On to step 8:
If we divide 236 by 69, we get 3 and a remainder of 29.
The next digit of our result is 3. 
Result so far: 773453.0
If we subtract 207 from 236, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
If we divide 290 by 69, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 773453.4
If we take 276 away from 290, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
69 can be fit into 140 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 773453.42
If we subtract 138 from 140, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
69 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 773453.42
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
69 can be fit into 200 2 times, resulting in a remainder of 62.
Put 2 as the next digit of the answer. 
Result so far: 773453.4202
If we subtract 138 from 200, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
The number 69 fits into 620 8 times, leaving a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 773453.42028
Deduct 552 from 620 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 14:
680 divided by 69 is 9 with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 773453.420289
Subtract 621 from 680 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 15:
69 goes into 590 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 773453.4202898
If we subtract 552 from 590, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 16:
380 divided by 69 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 773453.42028985
Deduct 345 from 380 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 773453.42028985 and a remainder of 3.5e-08.
