18057271 ÷ 918 
The aim is to understand the frequency of 918 in 18057271.

Step 1:
1 divided by 918 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 918

Step 2:
918 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 918

Moving on to step 3:
918 can be fit into 180 0 times, resulting in a remainder of 180.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 180 leaves us with 180.
Bring next digit (5) of the dividend behind the 180 and repeat the process: 1805 / 918

Step 4:
If we divide 1805 by 918, we get 1 and a remainder of 887.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 918 from 1805 leaves us with 887.
Grab the next digit (7) from the dividend, add it to 887, then carry on: 8877 / 918

On to step 5:
918 goes into 8877 9 times with a remainder of 615.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 615 after subtracting 8262 from 8877.
Grab the next digit (2) from the dividend, add it to 615, then carry on: 6152 / 918

Let's proceed to step 6:
6152 divided by 918 is 6 with a remainder of 644.
Write down 6 as next digit of the result. 
Result so far: 196.0
Subtract 5508 from 6152 to get 644.
Fetch the next digit (7) from the dividend, attach it to 644 and continue: 6447 / 918

On to step 7:
The number 918 fits into 6447 7 times, leaving a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 1967.0
The remainder is 21 after subtracting 6426 from 6447.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 918

On to step 8:
211 divided by 918 is 0 with a remainder of 211.
Write down 0 as next digit of the result. 
Result so far: 19670.0
If we take 0 away from 211, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 9:
918 goes into 2110 2 times with a remainder of 274.
Put 2 as the next digit of the answer. 
Result so far: 19670.2
Subtract 1836 from 2110 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 10:
918 can be fit into 2740 2 times, resulting in a remainder of 904.
The number 2 becomes the next digit in our result. 
Result so far: 19670.22
If we take 1836 away from 2740, we end up with 904.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9040, and continue the process.

Our division results in 19670.22 with a remaining 0.904.
