We divide 39489370 by 50
The aim is to understand the frequency of 50 in 39489370.

On to step 1:
When dividing 3 by 50, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 50

Step 2:
When dividing 39 by 50, we get 0 with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 50

Let's proceed to step 3:
The number 50 fits into 394 7 times, leaving a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 350 from 394 to get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 50

On to step 4:
When dividing 448 by 50, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 400 from 448, we get 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 50

Advancing to step 5:
The number 50 fits into 489 9 times, leaving a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 789.0
If we take 450 away from 489, we end up with 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 50

Let's proceed to step 6:
When dividing 393 by 50, we get 7 with a remainder of 43.
The next digit of our result is 7. 
Result so far: 7897.0
Deduct 350 from 393 and we're left with 43.
Take the next digit (7) from the dividend and append it to 43, then repeat: 437 / 50

Advancing to step 7:
If we divide 437 by 50, we get 8 and a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 78978.0
The remainder is 37 after subtracting 400 from 437.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 50

Step 8:
The number 50 fits into 370 7 times, leaving a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 789787.0
Subtracting 350 from 370 leaves us 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.

Step 9:
50 goes into 200 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 789787.4
Subtract 200 from 200 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.

Step 10:
50 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 789787.4
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.

Moving on to step 11:
50 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 789787.4
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 result is 789787.4 with a remainder of 0.0.
