89262149 divided by 166 
The aim is to understand the frequency of 166 in 89262149.

Advancing to step 1:
8 divided by 166 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 166

Step 2:
When dividing 89 by 166, we get 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Include the next digit (2) from the dividend after 89, then repeat: 892 / 166

Moving on to step 3:
892 divided by 166 is 5 with a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 830 from 892 and we're left with 62.
Fetch the next digit (6) from the dividend, attach it to 62 and continue: 626 / 166

Step 4:
If we divide 626 by 166, we get 3 and a remainder of 128.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Deduct 498 from 626 and we're left with 128.
Include the next digit (2) from the dividend after 128, then repeat: 1282 / 166

Going ahead to step 5:
1282 divided by 166 is 7 with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 537.0
Deduct 1162 from 1282 and we're left with 120.
Append the next digit (1) from the dividend to 120 and continue with: 1201 / 166

Advancing to step 6:
When dividing 1201 by 166, we get 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 5377.0
Deduct 1162 from 1201 and we're left with 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 166

Going ahead to step 7:
When dividing 394 by 166, we get 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 53772.0
If we subtract 332 from 394, we get 62.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 166

Going ahead to step 8:
The number 166 fits into 629 3 times, leaving a remainder of 131.
Write down 3 as next digit of the result. 
Result so far: 537723.0
If we subtract 498 from 629, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 9:
If we divide 1310 by 166, we get 7 and a remainder of 148.
The next digit of our result is 7. 
Result so far: 537723.7
The remainder is 148 after subtracting 1162 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 10:
The number 166 fits into 1480 8 times, leaving a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 537723.78
Subtract 1328 from 1480 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 11:
166 goes into 1520 9 times with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 537723.789
If we take 1494 away from 1520, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
When dividing 260 by 166, we get 1 with a remainder of 94.
Record the quotient 1 as the next digit in the result. 
Result so far: 537723.7891
Deduct 166 from 260 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 13:
940 divided by 166 is 5 with a remainder of 110.
Put 5 as the next digit of the answer. 
Result so far: 537723.78915
If we subtract 830 from 940, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 14:
If we divide 1100 by 166, we get 6 and a remainder of 104.
The next digit of our result is 6. 
Result so far: 537723.789156
Subtract 996 from 1100 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 15:
166 can be fit into 1040 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 537723.7891566
Subtracting 996 from 1040 leaves us 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.

The final result is 537723.7891566 with a remainder of 4.4e-07.
