Let's divide 76394906 by 166
The aim is to understand the frequency of 166 in 76394906.

Let's proceed to step 1:
If we divide 7 by 166, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 166

Advancing to step 2:
166 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 166

Step 3:
When dividing 763 by 166, we get 4 with a remainder of 99.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 664 away from 763, we end up with 99.
Fetch the next digit (9) from the dividend, attach it to 99 and continue: 999 / 166

Moving on to step 4:
166 goes into 999 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 46.0
The remainder is 3 after subtracting 996 from 999.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 166

Step 5:
If we divide 34 by 166, we get 0 and a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 460.0
Subtract 0 from 34 to get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 166

Advancing to step 6:
166 can be fit into 349 2 times, resulting in a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 4602.0
If we take 332 away from 349, we end up with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 166

On to step 7:
When dividing 170 by 166, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 46021.0
If we subtract 166 from 170, we get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 166

Moving on to step 8:
166 can be fit into 46 0 times, resulting in a remainder of 46.
Use 0 as the next digit of our solution. 
Result so far: 460210.0
If we subtract 0 from 46, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
When dividing 460 by 166, we get 2 with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 460210.2
Deduct 332 from 460 and we're left 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 10:
166 goes into 1280 7 times with a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 460210.27
If we subtract 1162 from 1280, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 11:
166 can be fit into 1180 7 times, resulting in a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 460210.277
Deduct 1162 from 1180 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 460210.277 and a remainder of 0.0018.
