27900886 ÷ 53 
The aim is to understand the frequency of 53 in 27900886.

On to step 1:
If we divide 2 by 53, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 53

Step 2:
27 divided by 53 is 0 with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 53

Step 3:
53 can be fit into 279 5 times, resulting in a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 265 from 279 leaves us with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 53

Let's proceed to step 4:
53 can be fit into 140 2 times, resulting in a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtract 106 from 140 to get 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 53

Advancing to step 5:
53 can be fit into 340 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 526.0
Deduct 318 from 340 and we're left with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 53

Going ahead to step 6:
53 goes into 228 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 5264.0
If we subtract 212 from 228, we get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 53

Advancing to step 7:
168 divided by 53 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 52643.0
Subtracting 159 from 168 leaves us with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 53

Let's proceed to step 8:
The number 53 fits into 96 1 times, leaving a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 526431.0
Deduct 53 from 96 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 9:
The number 53 fits into 430 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 526431.8
Subtracting 424 from 430 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
60 divided by 53 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 526431.81
Subtracting 53 from 60 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
70 divided by 53 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 526431.811
Subtract 53 from 70 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 526431.811 with a remaining 0.0017.
