201586 ÷ 50 
The aim is to understand the frequency of 50 in 201586.

Going ahead to step 1:
50 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 50

Going ahead to step 2:
50 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 50

Going ahead to step 3:
If we divide 201 by 50, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 200 from 201 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 50

Step 4:
15 divided by 50 is 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 50

Moving on to step 5:
If we divide 158 by 50, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 403.0
Subtract 150 from 158 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 50

Going ahead to step 6:
50 can be fit into 86 1 times, resulting in a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 4031.0
Deduct 50 from 86 and we're left with 36.
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 7:
When dividing 360 by 50, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 4031.7
Deduct 350 from 360 and we're left 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.

Moving on to step 8:
When dividing 100 by 50, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4031.72
The remainder is 0 after subtracting 100 from 100.
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 9:
0 divided by 50 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4031.72
Deduct 0 from 0 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.

Advancing to step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4031.72
If we subtract 0 from 0, we 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.

The final outcome is 4031.72, with a leftover of 0.0.
