45494221 ÷ 169 
The aim is to understand the frequency of 169 in 45494221.

Step 1:
If we divide 4 by 169, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 169

Going ahead to step 2:
169 goes into 45 0 times with a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 169

Let's proceed to step 3:
454 divided by 169 is 2 with a remainder of 116.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 338 from 454 and we're left with 116.
Fetch the next digit (9) from the dividend, attach it to 116 and continue: 1169 / 169

Advancing to step 4:
If we divide 1169 by 169, we get 6 and a remainder of 155.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 1014 away from 1169, we end up with 155.
Fetch the next digit (4) from the dividend, attach it to 155 and continue: 1554 / 169

Moving on to step 5:
169 goes into 1554 9 times with a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 269.0
Deduct 1521 from 1554 and we're left with 33.
Append the next digit (2) from the dividend to 33 and continue with: 332 / 169

Step 6:
169 goes into 332 1 times with a remainder of 163.
Record the quotient 1 as the next digit in the result. 
Result so far: 2691.0
Subtracting 169 from 332 leaves us with 163.
Include the next digit (2) from the dividend after 163, then repeat: 1632 / 169

On to step 7:
1632 divided by 169 is 9 with a remainder of 111.
The number 9 becomes the next digit in our result. 
Result so far: 26919.0
Deduct 1521 from 1632 and we're left with 111.
Take the next digit (1) from the dividend and append it to 111, then repeat: 1111 / 169

On to step 8:
1111 divided by 169 is 6 with a remainder of 97.
Put 6 as the next digit of the answer. 
Result so far: 269196.0
The remainder is 97 after subtracting 1014 from 1111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 9:
169 goes into 970 5 times with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 269196.5
Subtracting 845 from 970 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 10:
When dividing 1250 by 169, we get 7 with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 269196.57
Deduct 1183 from 1250 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
169 goes into 670 3 times with a remainder of 163.
Use 3 as the next digit of our solution. 
Result so far: 269196.573
Subtract 507 from 670 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 12:
When dividing 1630 by 169, we get 9 with a remainder of 109.
Write down 9 as next digit of the result. 
Result so far: 269196.5739
If we subtract 1521 from 1630, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 13:
169 goes into 1090 6 times with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 269196.57396
The remainder is 76 after subtracting 1014 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 14:
The number 169 fits into 760 4 times, leaving a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 269196.573964
Deduct 676 from 760 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
169 can be fit into 840 4 times, resulting in a remainder of 164.
Use 4 as the next digit of our solution. 
Result so far: 269196.5739644
Subtract 676 from 840 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

After the division, we end up with 269196.5739644 and a remainder of 1.64e-06.
