Let's divide 66560280 by 149
The aim is to understand the frequency of 149 in 66560280.

Going ahead to step 1:
When dividing 6 by 149, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 149

Advancing to step 2:
149 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (5) of the dividend behind the 66 and repeat the process: 665 / 149

Moving on to step 3:
149 goes into 665 4 times with a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 596 from 665 and we're left with 69.
Fetch the next digit (6) from the dividend, attach it to 69 and continue: 696 / 149

Step 4:
149 goes into 696 4 times with a remainder of 100.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 100 after subtracting 596 from 696.
Append the next digit (0) from the dividend to 100 and continue with: 1000 / 149

Moving on to step 5:
When dividing 1000 by 149, we get 6 with a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 446.0
Deduct 894 from 1000 and we're left with 106.
Append the next digit (2) from the dividend to 106 and continue with: 1062 / 149

On to step 6:
149 goes into 1062 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 4467.0
Deduct 1043 from 1062 and we're left with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 149

Step 7:
The number 149 fits into 198 1 times, leaving a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 44671.0
Subtracting 149 from 198 leaves us with 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 149

Let's proceed to step 8:
If we divide 490 by 149, we get 3 and a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 446713.0
Subtracting 447 from 490 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
If we divide 430 by 149, we get 2 and a remainder of 132.
The next digit of our result is 2. 
Result so far: 446713.2
Subtracting 298 from 430 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 10:
When dividing 1320 by 149, we get 8 with a remainder of 128.
Use 8 as the next digit of our solution. 
Result so far: 446713.28
Subtracting 1192 from 1320 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 11:
149 goes into 1280 8 times with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 446713.288
Subtract 1192 from 1280 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final outcome is 446713.288, with a leftover of 0.0088.
