31944441 ÷ 166 
The aim is to understand the frequency of 166 in 31944441.

Going ahead to step 1:
When dividing 3 by 166, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 166

Step 2:
When dividing 31 by 166, we get 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 166

On to step 3:
319 divided by 166 is 1 with a remainder of 153.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 153 after subtracting 166 from 319.
Fetch the next digit (4) from the dividend, attach it to 153 and continue: 1534 / 166

Step 4:
When dividing 1534 by 166, we get 9 with a remainder of 40.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 1494 from 1534 leaves us with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 166

On to step 5:
404 divided by 166 is 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Subtract 332 from 404 to get 72.
Fetch the next digit (4) from the dividend, attach it to 72 and continue: 724 / 166

Step 6:
The number 166 fits into 724 4 times, leaving a remainder of 60.
The next digit of our result is 4. 
Result so far: 1924.0
Subtracting 664 from 724 leaves us with 60.
Take the next digit (4) from the dividend and append it to 60, then repeat: 604 / 166

On to step 7:
When dividing 604 by 166, we get 3 with a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 19243.0
Subtracting 498 from 604 leaves us with 106.
Bring next digit (1) of the dividend behind the 106 and repeat the process: 1061 / 166

Step 8:
166 goes into 1061 6 times with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 192436.0
Deduct 996 from 1061 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
When dividing 650 by 166, we get 3 with a remainder of 152.
Record the quotient 3 as the next digit in the result. 
Result so far: 192436.3
Subtract 498 from 650 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.

On to step 10:
166 can be fit into 1520 9 times, resulting in a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 192436.39
The remainder is 26 after subtracting 1494 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
The number 166 fits into 260 1 times, leaving a remainder of 94.
Use 1 as the next digit of our solution. 
Result so far: 192436.391
Subtract 166 from 260 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 12:
The number 166 fits into 940 5 times, leaving a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 192436.3915
Subtract 830 from 940 to 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 13:
When dividing 1100 by 166, we get 6 with a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 192436.39156
Subtracting 996 from 1100 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 14:
If we divide 1040 by 166, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 192436.391566
The remainder is 44 after subtracting 996 from 1040.
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 192436.391566 with a remainder of 4.4e-06.
