66785847 ÷ 148 
The aim is to understand the frequency of 148 in 66785847.

Moving on to step 1:
148 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 148

Let's proceed to step 2:
The number 148 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 148

Going ahead to step 3:
If we divide 667 by 148, we get 4 and a remainder of 75.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 75 after subtracting 592 from 667.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 148

Going ahead to step 4:
758 divided by 148 is 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 740 from 758 leaves us with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 148

Step 5:
185 divided by 148 is 1 with a remainder of 37.
The next digit of our result is 1. 
Result so far: 451.0
Deduct 148 from 185 and we're left with 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 148

Going ahead to step 6:
If we divide 378 by 148, we get 2 and a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 4512.0
Subtract 296 from 378 to get 82.
Fetch the next digit (4) from the dividend, attach it to 82 and continue: 824 / 148

Let's proceed to step 7:
824 divided by 148 is 5 with a remainder of 84.
Put 5 as the next digit of the answer. 
Result so far: 45125.0
If we take 740 away from 824, we end up with 84.
Include the next digit (7) from the dividend after 84, then repeat: 847 / 148

Going ahead to step 8:
847 divided by 148 is 5 with a remainder of 107.
The next digit of our result is 5. 
Result so far: 451255.0
Deduct 740 from 847 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 9:
If we divide 1070 by 148, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 451255.7
If we take 1036 away from 1070, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
340 divided by 148 is 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 451255.72
If we take 296 away from 340, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
If we divide 440 by 148, we get 2 and a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 451255.722
If we subtract 296 from 440, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final result is 451255.722 with a remainder of 0.0144.
