642089 divided by 50 
The aim is to understand the frequency of 50 in 642089.

Let's proceed to step 1:
50 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 50

On to step 2:
64 divided by 50 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 50 from 64, we get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 50

On to step 3:
When dividing 142 by 50, we get 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 100 from 142 and we're left with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 50

Advancing to step 4:
The number 50 fits into 420 8 times, leaving a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtract 400 from 420 to get 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 50

Moving on to step 5:
When dividing 208 by 50, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1284.0
If we subtract 200 from 208, we get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 50

Going ahead to step 6:
If we divide 89 by 50, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 12841.0
If we subtract 50 from 89, we 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.

Moving on to step 7:
The number 50 fits into 390 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 12841.7
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.

Step 8:
When dividing 400 by 50, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 12841.78
If we subtract 400 from 400, 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.

Let's proceed 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: 12841.78
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.

Let's proceed to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12841.78
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.

The final outcome is 12841.78, with a leftover of 0.0.
