We look at the division of 51348542 by 186 
The aim is to understand the frequency of 186 in 51348542.

Advancing to step 1:
186 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 186

Advancing to step 2:
51 divided by 186 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 186

Going ahead to step 3:
513 divided by 186 is 2 with a remainder of 141.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 372 from 513 to get 141.
Bring next digit (4) of the dividend behind the 141 and repeat the process: 1414 / 186

Step 4:
If we divide 1414 by 186, we get 7 and a remainder of 112.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 112 after subtracting 1302 from 1414.
Take the next digit (8) from the dividend and append it to 112, then repeat: 1128 / 186

Advancing to step 5:
1128 divided by 186 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 276.0
If we subtract 1116 from 1128, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 186

Going ahead to step 6:
When dividing 125 by 186, we get 0 with a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 2760.0
If we subtract 0 from 125, we get 125.
Fetch the next digit (4) from the dividend, attach it to 125 and continue: 1254 / 186

On to step 7:
The number 186 fits into 1254 6 times, leaving a remainder of 138.
The next digit of our result is 6. 
Result so far: 27606.0
Deduct 1116 from 1254 and we're left with 138.
Bring next digit (2) of the dividend behind the 138 and repeat the process: 1382 / 186

On to step 8:
The number 186 fits into 1382 7 times, leaving a remainder of 80.
The number 7 becomes the next digit in our result. 
Result so far: 276067.0
Subtract 1302 from 1382 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
When dividing 800 by 186, we get 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 276067.4
Subtracting 744 from 800 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
If we divide 560 by 186, we get 3 and a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 276067.43
Deduct 558 from 560 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
If we divide 20 by 186, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 276067.43
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
200 divided by 186 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 276067.4301
If we subtract 186 from 200, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
If we divide 140 by 186, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 276067.4301
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 14:
If we divide 1400 by 186, we get 7 and a remainder of 98.
The number 7 becomes the next digit in our result. 
Result so far: 276067.430107
If we take 1302 away from 1400, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 15:
The number 186 fits into 980 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 276067.4301075
Subtract 930 from 980 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 16:
186 can be fit into 500 2 times, resulting in a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 276067.43010752
If we take 372 away from 500, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

After the division, we end up with 276067.43010752 and a remainder of 1.28e-07.
