We divide 51912271 by 201
The aim is to understand the frequency of 201 in 51912271.

Moving on to step 1:
5 divided by 201 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 201

Step 2:
201 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 201

On to step 3:
519 divided by 201 is 2 with a remainder of 117.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 402 from 519 and we're left with 117.
Append the next digit (1) from the dividend to 117 and continue with: 1171 / 201

Step 4:
201 can be fit into 1171 5 times, resulting in a remainder of 166.
The next digit of our result is 5. 
Result so far: 25.0
Subtracting 1005 from 1171 leaves us with 166.
Fetch the next digit (2) from the dividend, attach it to 166 and continue: 1662 / 201

Going ahead to step 5:
The number 201 fits into 1662 8 times, leaving a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 258.0
Subtracting 1608 from 1662 leaves us with 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 201

Going ahead to step 6:
201 can be fit into 542 2 times, resulting in a remainder of 140.
Put 2 as the next digit of the answer. 
Result so far: 2582.0
Subtracting 402 from 542 leaves us with 140.
Grab the next digit (7) from the dividend, add it to 140, then carry on: 1407 / 201

Advancing to step 7:
1407 divided by 201 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 25827.0
The remainder is 0 after subtracting 1407 from 1407.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 201

Advancing to step 8:
201 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 258270.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
If we divide 10 by 201, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 258270.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
The number 201 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 258270.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 258270.0 with a remaining 0.1.
