90487340 ÷ 50 
The aim is to understand the frequency of 50 in 90487340.

Let's proceed to step 1:
50 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 50

Let's proceed to step 2:
90 divided by 50 is 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 50 from 90 to get 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 50

Going ahead to step 3:
404 divided by 50 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 4 after subtracting 400 from 404.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 50

On to step 4:
50 can be fit into 48 0 times, resulting in a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
The remainder is 48 after subtracting 0 from 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 50

Moving on to step 5:
487 divided by 50 is 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 1809.0
Subtracting 450 from 487 leaves us with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 50

Moving on to step 6:
50 goes into 373 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 18097.0
If we take 350 away from 373, we end up with 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 50

Advancing to step 7:
If we divide 234 by 50, we get 4 and a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 180974.0
The remainder is 34 after subtracting 200 from 234.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 50

Let's proceed to step 8:
50 goes into 340 6 times with a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 1809746.0
If we take 300 away from 340, we end up 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.

Going ahead to step 9:
When dividing 400 by 50, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 1809746.8
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.

Going ahead 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: 1809746.8
Subtract 0 from 0 to 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.

Advancing to step 11:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1809746.8
Subtract 0 from 0 to 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 1809746.8, and the remainder is 0.0.
