818370 divided by 50 
The aim is to understand the frequency of 50 in 818370.

Moving on to step 1:
The number 50 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 50

Moving on to step 2:
50 goes into 81 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 31 after subtracting 50 from 81.
Fetch the next digit (8) from the dividend, attach it to 31 and continue: 318 / 50

Advancing to step 3:
If we divide 318 by 50, we get 6 and a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 300 from 318 and we're left with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 50

Moving on to step 4:
When dividing 183 by 50, we get 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 163.0
The remainder is 33 after subtracting 150 from 183.
Append the next digit (7) from the dividend to 33 and continue with: 337 / 50

Advancing to step 5:
The number 50 fits into 337 6 times, leaving a remainder of 37.
Put 6 as the next digit of the answer. 
Result so far: 1636.0
If we subtract 300 from 337, we get 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 50

Advancing to step 6:
50 goes into 370 7 times with a remainder of 20.
The next digit of our result is 7. 
Result so far: 16367.0
If we take 350 away from 370, 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.

Moving on to step 7:
50 goes into 200 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 16367.4
If we subtract 200 from 200, 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.

On to step 8:
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: 16367.4
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.

Advancing to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16367.4
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.

The quotient of the division is 16367.4, and the remainder is 0.0.
