We divide 90752355 by 186
The aim is to understand the frequency of 186 in 90752355.

Going ahead to step 1:
9 divided by 186 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 186

Step 2:
When dividing 90 by 186, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Append the next digit (7) from the dividend to 90 and continue with: 907 / 186

On to step 3:
The number 186 fits into 907 4 times, leaving a remainder of 163.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 744 from 907 and we're left with 163.
Fetch the next digit (5) from the dividend, attach it to 163 and continue: 1635 / 186

Going ahead to step 4:
If we divide 1635 by 186, we get 8 and a remainder of 147.
Use 8 as the next digit of our solution. 
Result so far: 48.0
The remainder is 147 after subtracting 1488 from 1635.
Fetch the next digit (2) from the dividend, attach it to 147 and continue: 1472 / 186

On to step 5:
186 goes into 1472 7 times with a remainder of 170.
Use 7 as the next digit of our solution. 
Result so far: 487.0
Deduct 1302 from 1472 and we're left with 170.
Take the next digit (3) from the dividend and append it to 170, then repeat: 1703 / 186

Step 6:
When dividing 1703 by 186, we get 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 4879.0
If we take 1674 away from 1703, we end up with 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 186

On to step 7:
186 goes into 295 1 times with a remainder of 109.
The next digit of our result is 1. 
Result so far: 48791.0
Subtracting 186 from 295 leaves us with 109.
Fetch the next digit (5) from the dividend, attach it to 109 and continue: 1095 / 186

Advancing to step 8:
When dividing 1095 by 186, we get 5 with a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 487915.0
If we take 930 away from 1095, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 9:
If we divide 1650 by 186, we get 8 and a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 487915.8
If we take 1488 away from 1650, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 10:
186 can be fit into 1620 8 times, resulting in a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 487915.88
Deduct 1488 from 1620 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final outcome is 487915.88, with a leftover of 0.132.
