We're dividing 80615284 by 169 
The aim is to understand the frequency of 169 in 80615284.

Moving on to step 1:
169 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 169

Moving on to step 2:
If we divide 80 by 169, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 169

On to step 3:
When dividing 806 by 169, we get 4 with a remainder of 130.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 130 after subtracting 676 from 806.
Fetch the next digit (1) from the dividend, attach it to 130 and continue: 1301 / 169

Going ahead to step 4:
The number 169 fits into 1301 7 times, leaving a remainder of 118.
Put 7 as the next digit of the answer. 
Result so far: 47.0
Subtracting 1183 from 1301 leaves us with 118.
Append the next digit (5) from the dividend to 118 and continue with: 1185 / 169

Moving on to step 5:
1185 divided by 169 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 477.0
The remainder is 2 after subtracting 1183 from 1185.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 169

Going ahead to step 6:
The number 169 fits into 22 0 times, leaving a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 4770.0
If we take 0 away from 22, we end up with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 169

On to step 7:
228 divided by 169 is 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 47701.0
If we subtract 169 from 228, we get 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 169

Let's proceed to step 8:
594 divided by 169 is 3 with a remainder of 87.
The next digit of our result is 3. 
Result so far: 477013.0
The remainder is 87 after subtracting 507 from 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 9:
870 divided by 169 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 477013.5
If we take 845 away from 870, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
250 divided by 169 is 1 with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 477013.51
Subtract 169 from 250 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 11:
If we divide 810 by 169, we get 4 and a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 477013.514
Deduct 676 from 810 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 12:
The number 169 fits into 1340 7 times, leaving a remainder of 157.
The next digit of our result is 7. 
Result so far: 477013.5147
The remainder is 157 after subtracting 1183 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 13:
169 goes into 1570 9 times with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 477013.51479
The remainder is 49 after subtracting 1521 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 14:
169 goes into 490 2 times with a remainder of 152.
The next digit of our result is 2. 
Result so far: 477013.514792
The remainder is 152 after subtracting 338 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 15:
If we divide 1520 by 169, we get 8 and a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 477013.5147928
The remainder is 168 after subtracting 1352 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 16:
The number 169 fits into 1680 9 times, leaving a remainder of 159.
Write down 9 as next digit of the result. 
Result so far: 477013.51479289
If we take 1521 away from 1680, we end up with 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The quotient of the division is 477013.51479289, and the remainder is 1.59e-07.
