71398010 ÷ 52 
The aim is to understand the frequency of 52 in 71398010.

On to step 1:
52 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 52

Let's proceed to step 2:
71 divided by 52 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 52 from 71, we get 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 52

Step 3:
If we divide 193 by 52, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 156 away from 193, we end up with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 52

On to step 4:
If we divide 379 by 52, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 364 from 379 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 52

On to step 5:
When dividing 158 by 52, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1373.0
Subtract 156 from 158 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 52

Step 6:
If we divide 20 by 52, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 13730.0
Subtract 0 from 20 to get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 52

On to step 7:
When dividing 201 by 52, we get 3 with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 137303.0
If we take 156 away from 201, we end up with 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 52

Step 8:
If we divide 450 by 52, we get 8 and a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 1373038.0
Subtracting 416 from 450 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
52 can be fit into 340 6 times, resulting in a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 1373038.6
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
When dividing 280 by 52, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 1373038.65
If we subtract 260 from 280, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
52 can be fit into 200 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 1373038.653
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
If we divide 440 by 52, we get 8 and a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 1373038.6538
Subtract 416 from 440 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
240 divided by 52 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 1373038.65384
The remainder is 32 after subtracting 208 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
The number 52 fits into 320 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1373038.653846
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 15:
If we divide 80 by 52, we get 1 and a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1373038.6538461
Deduct 52 from 80 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 16:
52 can be fit into 280 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 1373038.65384615
If we take 260 away from 280, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 1373038.65384615 with a remainder of 2e-08.
