49387791 divided by 186 
The aim is to understand the frequency of 186 in 49387791.

Moving on to step 1:
If we divide 4 by 186, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 186

Step 2:
The number 186 fits into 49 0 times, leaving a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Grab the next digit (3) from the dividend, add it to 49, then carry on: 493 / 186

Going ahead to step 3:
493 divided by 186 is 2 with a remainder of 121.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 121 after subtracting 372 from 493.
Bring next digit (8) of the dividend behind the 121 and repeat the process: 1218 / 186

Let's proceed to step 4:
If we divide 1218 by 186, we get 6 and a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 102 after subtracting 1116 from 1218.
Fetch the next digit (7) from the dividend, attach it to 102 and continue: 1027 / 186

Let's proceed to step 5:
The number 186 fits into 1027 5 times, leaving a remainder of 97.
Write down 5 as next digit of the result. 
Result so far: 265.0
Deduct 930 from 1027 and we're left with 97.
Take the next digit (7) from the dividend and append it to 97, then repeat: 977 / 186

Step 6:
186 goes into 977 5 times with a remainder of 47.
Put 5 as the next digit of the answer. 
Result so far: 2655.0
If we take 930 away from 977, we end up with 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 186

Going ahead to step 7:
186 can be fit into 479 2 times, resulting in a remainder of 107.
Record the quotient 2 as the next digit in the result. 
Result so far: 26552.0
The remainder is 107 after subtracting 372 from 479.
Append the next digit (1) from the dividend to 107 and continue with: 1071 / 186

On to step 8:
186 goes into 1071 5 times with a remainder of 141.
Put 5 as the next digit of the answer. 
Result so far: 265525.0
The remainder is 141 after subtracting 930 from 1071.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 9:
The number 186 fits into 1410 7 times, leaving a remainder of 108.
The number 7 becomes the next digit in our result. 
Result so far: 265525.7
Subtracting 1302 from 1410 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 10:
1080 divided by 186 is 5 with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 265525.75
The remainder is 150 after subtracting 930 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
186 can be fit into 1500 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 265525.758
If we subtract 1488 from 1500, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
When dividing 120 by 186, we get 0 with a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 265525.758
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
1200 divided by 186 is 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 265525.75806
If we take 1116 away from 1200, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 14:
If we divide 840 by 186, we get 4 and a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 265525.758064
If we take 744 away from 840, we end up 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 15:
When dividing 960 by 186, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 265525.7580645
If we subtract 930 from 960, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 16:
If we divide 300 by 186, we get 1 and a remainder of 114.
The next digit of our result is 1. 
Result so far: 265525.75806451
Subtracting 186 from 300 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final outcome is 265525.75806451, with a leftover of 1.14e-07.
