49585770 divided by 166 
The aim is to understand the frequency of 166 in 49585770.

Going ahead to step 1:
4 divided by 166 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 166

Advancing to step 2:
When dividing 49 by 166, we get 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 166

Going ahead to step 3:
495 divided by 166 is 2 with a remainder of 163.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 332 away from 495, we end up with 163.
Include the next digit (8) from the dividend after 163, then repeat: 1638 / 166

On to step 4:
1638 divided by 166 is 9 with a remainder of 144.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 144 after subtracting 1494 from 1638.
Fetch the next digit (5) from the dividend, attach it to 144 and continue: 1445 / 166

Let's proceed to step 5:
When dividing 1445 by 166, we get 8 with a remainder of 117.
Put 8 as the next digit of the answer. 
Result so far: 298.0
Subtract 1328 from 1445 to get 117.
Append the next digit (7) from the dividend to 117 and continue with: 1177 / 166

Step 6:
1177 divided by 166 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 2987.0
Subtract 1162 from 1177 to get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 166

Moving on to step 7:
When dividing 157 by 166, we get 0 with a remainder of 157.
Put 0 as the next digit of the answer. 
Result so far: 29870.0
The remainder is 157 after subtracting 0 from 157.
Take the next digit (0) from the dividend and append it to 157, then repeat: 1570 / 166

Let's proceed to step 8:
If we divide 1570 by 166, we get 9 and a remainder of 76.
Put 9 as the next digit of the answer. 
Result so far: 298709.0
Deduct 1494 from 1570 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
The number 166 fits into 760 4 times, leaving a remainder of 96.
Record the quotient 4 as the next digit in the result. 
Result so far: 298709.4
Subtracting 664 from 760 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 10:
If we divide 960 by 166, we get 5 and a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 298709.45
If we take 830 away from 960, we end up with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 11:
The number 166 fits into 1300 7 times, leaving a remainder of 138.
Write down 7 as next digit of the result. 
Result so far: 298709.457
The remainder is 138 after subtracting 1162 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 12:
166 can be fit into 1380 8 times, resulting in a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 298709.4578
The remainder is 52 after subtracting 1328 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
If we divide 520 by 166, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 298709.45783
Deduct 498 from 520 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
If we divide 220 by 166, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 298709.457831
Subtracting 166 from 220 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 15:
166 goes into 540 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 298709.4578313
Subtract 498 from 540 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 16:
166 goes into 420 2 times with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 298709.45783132
Subtracting 332 from 420 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 298709.45783132 with a balance of 8.8e-08.
