51232790 ÷ 169 
The aim is to understand the frequency of 169 in 51232790.

Going ahead to step 1:
169 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 169

Moving on to step 2:
169 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 169

Let's proceed to step 3:
When dividing 512 by 169, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 5 after subtracting 507 from 512.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 169

Moving on to step 4:
If we divide 53 by 169, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 53 to get 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 169

Moving on to step 5:
169 goes into 532 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
If we subtract 507 from 532, we get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 169

Going ahead to step 6:
When dividing 257 by 169, we get 1 with a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 3031.0
Subtract 169 from 257 to get 88.
Bring next digit (9) of the dividend behind the 88 and repeat the process: 889 / 169

Moving on to step 7:
If we divide 889 by 169, we get 5 and a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 30315.0
Subtract 845 from 889 to get 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 169

Step 8:
The number 169 fits into 440 2 times, leaving a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 303152.0
If we subtract 338 from 440, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
When dividing 1020 by 169, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 303152.6
Subtracting 1014 from 1020 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
When dividing 60 by 169, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 303152.6
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
When dividing 600 by 169, we get 3 with a remainder of 93.
The next digit of our result is 3. 
Result so far: 303152.603
The remainder is 93 after subtracting 507 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 12:
169 can be fit into 930 5 times, resulting in a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 303152.6035
Subtract 845 from 930 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 13:
169 goes into 850 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 303152.60355
If we subtract 845 from 850, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 303152.60355 and a remainder of 5e-06.
