We're dividing 73911212 by 50 
The aim is to understand the frequency of 50 in 73911212.

On to step 1:
50 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 50

Step 2:
73 divided by 50 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 50 from 73 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 50

Going ahead to step 3:
50 can be fit into 239 4 times, resulting in a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 200 from 239, we get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 50

Let's proceed to step 4:
The number 50 fits into 391 7 times, leaving a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 147.0
If we subtract 350 from 391, we get 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 50

Step 5:
411 divided by 50 is 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 1478.0
If we take 400 away from 411, we end up with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 50

Moving on to step 6:
112 divided by 50 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 14782.0
Subtract 100 from 112 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 50

Let's proceed to step 7:
If we divide 121 by 50, we get 2 and a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 147822.0
Deduct 100 from 121 and we're left with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 50

Let's proceed to step 8:
50 goes into 212 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 1478224.0
If we subtract 200 from 212, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 50, we get 2 and a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 1478224.2
Subtract 100 from 120 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
If we divide 200 by 50, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1478224.24
Subtracting 200 from 200 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.

Let's proceed to step 11:
50 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1478224.24
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.

Let's proceed to step 12:
0 divided by 50 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1478224.24
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.

Our division results in 1478224.24 with a remaining 0.0.
