We divide 76539891 by 166
The aim is to understand the frequency of 166 in 76539891.

On to step 1:
166 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 166

Advancing to step 2:
166 can be fit into 76 0 times, resulting in a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 166

On to step 3:
166 goes into 765 4 times with a remainder of 101.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 664 from 765, we get 101.
Take the next digit (3) from the dividend and append it to 101, then repeat: 1013 / 166

On to step 4:
When dividing 1013 by 166, we get 6 with a remainder of 17.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 996 from 1013 to get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 166

Advancing to step 5:
166 can be fit into 179 1 times, resulting in a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 461.0
If we take 166 away from 179, we end up with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 166

Moving on to step 6:
138 divided by 166 is 0 with a remainder of 138.
Use 0 as the next digit of our solution. 
Result so far: 4610.0
If we take 0 away from 138, we end up with 138.
Include the next digit (9) from the dividend after 138, then repeat: 1389 / 166

Going ahead to step 7:
1389 divided by 166 is 8 with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 46108.0
Subtracting 1328 from 1389 leaves us with 61.
Fetch the next digit (1) from the dividend, attach it to 61 and continue: 611 / 166

Advancing to step 8:
166 can be fit into 611 3 times, resulting in a remainder of 113.
The next digit of our result is 3. 
Result so far: 461083.0
If we take 498 away from 611, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 9:
166 can be fit into 1130 6 times, resulting in a remainder of 134.
The next digit of our result is 6. 
Result so far: 461083.6
The remainder is 134 after subtracting 996 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
166 can be fit into 1340 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 461083.68
The remainder is 12 after subtracting 1328 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
166 can be fit into 120 0 times, resulting in a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 461083.68
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 12:
The number 166 fits into 1200 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 461083.6807
Subtracting 1162 from 1200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
380 divided by 166 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 461083.68072
The remainder is 48 after subtracting 332 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
166 can be fit into 480 2 times, resulting in a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 461083.680722
Subtract 332 from 480 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

In conclusion, the division gives 461083.680722 with a balance of 1.48e-05.
