We look at the division of 91321878 by 185 
The aim is to understand the frequency of 185 in 91321878.

Moving on to step 1:
185 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 185

Advancing to step 2:
185 goes into 91 0 times with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Include the next digit (3) from the dividend after 91, then repeat: 913 / 185

Going ahead to step 3:
185 can be fit into 913 4 times, resulting in a remainder of 173.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 173 after subtracting 740 from 913.
Bring next digit (2) of the dividend behind the 173 and repeat the process: 1732 / 185

Advancing to step 4:
If we divide 1732 by 185, we get 9 and a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 67 after subtracting 1665 from 1732.
Bring next digit (1) of the dividend behind the 67 and repeat the process: 671 / 185

Let's proceed to step 5:
185 goes into 671 3 times with a remainder of 116.
Record the quotient 3 as the next digit in the result. 
Result so far: 493.0
The remainder is 116 after subtracting 555 from 671.
Append the next digit (8) from the dividend to 116 and continue with: 1168 / 185

On to step 6:
185 goes into 1168 6 times with a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 4936.0
If we take 1110 away from 1168, we end up with 58.
Include the next digit (7) from the dividend after 58, then repeat: 587 / 185

Let's proceed to step 7:
When dividing 587 by 185, we get 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 49363.0
If we subtract 555 from 587, we get 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 185

Let's proceed to step 8:
If we divide 328 by 185, we get 1 and a remainder of 143.
Record the quotient 1 as the next digit in the result. 
Result so far: 493631.0
If we subtract 185 from 328, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 9:
185 can be fit into 1430 7 times, resulting in a remainder of 135.
Put 7 as the next digit of the answer. 
Result so far: 493631.7
If we subtract 1295 from 1430, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

On to step 10:
When dividing 1350 by 185, we get 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 493631.77
Subtract 1295 from 1350 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 493631.77, with a leftover of 0.055.
