Let's divide 15941636 by 50
The aim is to understand the frequency of 50 in 15941636.

On to step 1:
50 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 50

Advancing to step 2:
50 can be fit into 15 0 times, resulting in a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 50

Moving on to step 3:
50 can be fit into 159 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 150 from 159, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 50

Let's proceed to step 4:
If we divide 94 by 50, we get 1 and a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 50 from 94, we get 44.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 50

On to step 5:
The number 50 fits into 441 8 times, leaving a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 318.0
If we take 400 away from 441, we end up with 41.
Grab the next digit (6) from the dividend, add it to 41, then carry on: 416 / 50

Going ahead to step 6:
When dividing 416 by 50, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3188.0
If we take 400 away from 416, we end up with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 50

Going ahead to step 7:
50 goes into 163 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 31883.0
If we subtract 150 from 163, we get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 50

Advancing to step 8:
If we divide 136 by 50, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 318832.0
The remainder is 36 after subtracting 100 from 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
When dividing 360 by 50, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 318832.7
Subtracting 350 from 360 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
The number 50 fits into 100 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 318832.72
Deduct 100 from 100 and we're left 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.

Moving on to step 11:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 318832.72
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 12:
When dividing 0 by 50, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 318832.72
The remainder is 0 after subtracting 0 from 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 final outcome is 318832.72, with a leftover of 0.0.
