631605 divided by 52 
The aim is to understand the frequency of 52 in 631605.

Step 1:
If we divide 6 by 52, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 52

Going ahead to step 2:
The number 52 fits into 63 1 times, leaving a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 52 from 63, we get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 52

On to step 3:
If we divide 111 by 52, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 104 from 111 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 52

On to step 4:
52 can be fit into 76 1 times, resulting in a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we subtract 52 from 76, we get 24.
Include the next digit (0) from the dividend after 24, then repeat: 240 / 52

Let's proceed to step 5:
If we divide 240 by 52, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 1214.0
If we subtract 208 from 240, we get 32.
Bring next digit (5) of the dividend behind the 32 and repeat the process: 325 / 52

Let's proceed to step 6:
The number 52 fits into 325 6 times, leaving a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 12146.0
Subtracting 312 from 325 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 52, we get 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 12146.2
The remainder is 26 after subtracting 104 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
52 goes into 260 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12146.25
The remainder is 0 after subtracting 260 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 52, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12146.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 52 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12146.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 12146.25, and the remainder is 0.0.
