212489 ÷ 50 
The aim is to understand the frequency of 50 in 212489.

Moving on to step 1:
50 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 50

Let's proceed to step 2:
The number 50 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 50

Moving on to step 3:
The number 50 fits into 212 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 200 from 212, we get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 50

Step 4:
If we divide 124 by 50, we get 2 and a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 100 from 124 and we're left with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 50

Let's proceed to step 5:
When dividing 248 by 50, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 424.0
The remainder is 48 after subtracting 200 from 248.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 50

Advancing to step 6:
The number 50 fits into 489 9 times, leaving a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 4249.0
Subtract 450 from 489 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
50 goes into 390 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 4249.7
Subtracting 350 from 390 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
The number 50 fits into 400 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 4249.78
If we take 400 away from 400, 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.

Step 9:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4249.78
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:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4249.78
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 quotient of the division is 4249.78, and the remainder is 0.0.
