We're dividing 890145 by 50 
The aim is to understand the frequency of 50 in 890145.

Going ahead to step 1:
When dividing 8 by 50, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 50

On to step 2:
50 goes into 89 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 50 from 89 to get 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 50

Step 3:
390 divided by 50 is 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 350 from 390 and we're left with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 50

Going ahead to step 4:
50 goes into 401 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
Subtracting 400 from 401 leaves us with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 50

Step 5:
When dividing 14 by 50, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 1780.0
Subtracting 0 from 14 leaves us with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 50

Let's proceed to step 6:
When dividing 145 by 50, we get 2 with a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 17802.0
If we subtract 100 from 145, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 50 fits into 450 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 17802.9
Subtracting 450 from 450 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.

Step 8:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 17802.9
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.

Step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17802.9
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.

The quotient of the division is 17802.9, and the remainder is 0.0.
