We're dividing 715639 by 50 
The aim is to understand the frequency of 50 in 715639.

Advancing to step 1:
50 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 50

On to step 2:
50 goes into 71 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 50 from 71 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 50

Step 3:
50 goes into 215 4 times with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 200 from 215 leaves us with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 50

On to step 4:
If we divide 156 by 50, we get 3 and a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtracting 150 from 156 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 50

Moving on to step 5:
63 divided by 50 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1431.0
Subtract 50 from 63 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 50

Step 6:
If we divide 139 by 50, we get 2 and a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 14312.0
If we take 100 away from 139, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
390 divided by 50 is 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 14312.7
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:
50 can be fit into 400 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 14312.78
Subtracting 400 from 400 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.

On to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14312.78
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 10:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14312.78
The remainder is 0 after subtracting 0 from 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 14312.78 with a remainder of 0.0.
