48402963 ÷ 166 
The aim is to understand the frequency of 166 in 48402963.

On to step 1:
166 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 166

On to step 2:
166 can be fit into 48 0 times, resulting in a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Bring next digit (4) of the dividend behind the 48 and repeat the process: 484 / 166

Going ahead to step 3:
484 divided by 166 is 2 with a remainder of 152.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 152 after subtracting 332 from 484.
Include the next digit (0) from the dividend after 152, then repeat: 1520 / 166

Step 4:
When dividing 1520 by 166, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we take 1494 away from 1520, we end up with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 166

Step 5:
If we divide 262 by 166, we get 1 and a remainder of 96.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
Deduct 166 from 262 and we're left with 96.
Include the next digit (9) from the dividend after 96, then repeat: 969 / 166

Let's proceed to step 6:
When dividing 969 by 166, we get 5 with a remainder of 139.
Write down 5 as next digit of the result. 
Result so far: 2915.0
If we subtract 830 from 969, we get 139.
Bring next digit (6) of the dividend behind the 139 and repeat the process: 1396 / 166

Step 7:
166 goes into 1396 8 times with a remainder of 68.
The next digit of our result is 8. 
Result so far: 29158.0
The remainder is 68 after subtracting 1328 from 1396.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 166

Advancing to step 8:
If we divide 683 by 166, we get 4 and a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 291584.0
Subtract 664 from 683 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
166 can be fit into 190 1 times, resulting in a remainder of 24.
The next digit of our result is 1. 
Result so far: 291584.1
If we subtract 166 from 190, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
240 divided by 166 is 1 with a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 291584.11
The remainder is 74 after subtracting 166 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 291584.11 and a remainder of 0.074.
