Let's divide 73521617 by 149
The aim is to understand the frequency of 149 in 73521617.

Advancing to step 1:
If we divide 7 by 149, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 149

Let's proceed to step 2:
When dividing 73 by 149, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 149

Step 3:
If we divide 735 by 149, we get 4 and a remainder of 139.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 596 from 735 and we're left with 139.
Include the next digit (2) from the dividend after 139, then repeat: 1392 / 149

On to step 4:
The number 149 fits into 1392 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 49.0
Deduct 1341 from 1392 and we're left with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 149

Moving on to step 5:
If we divide 511 by 149, we get 3 and a remainder of 64.
The next digit of our result is 3. 
Result so far: 493.0
Subtracting 447 from 511 leaves us with 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 149

Going ahead to step 6:
The number 149 fits into 646 4 times, leaving a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 4934.0
Subtracting 596 from 646 leaves us with 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 149

Step 7:
When dividing 501 by 149, we get 3 with a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 49343.0
Deduct 447 from 501 and we're left with 54.
Grab the next digit (7) from the dividend, add it to 54, then carry on: 547 / 149

Step 8:
The number 149 fits into 547 3 times, leaving a remainder of 100.
Record the quotient 3 as the next digit in the result. 
Result so far: 493433.0
If we subtract 447 from 547, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
1000 divided by 149 is 6 with a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 493433.6
Deduct 894 from 1000 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 10:
149 can be fit into 1060 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 493433.67
The remainder is 17 after subtracting 1043 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
149 can be fit into 170 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 493433.671
The remainder is 21 after subtracting 149 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
210 divided by 149 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 493433.6711
If we take 149 away from 210, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Our division results in 493433.6711 with a remaining 0.00061.
