Let's divide 353700 by 50
The aim is to understand the frequency of 50 in 353700.

Advancing to step 1:
The number 50 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 50

Step 2:
50 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 50

Let's proceed to step 3:
50 can be fit into 353 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 3 after subtracting 350 from 353.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 50

On to step 4:
If we divide 37 by 50, we get 0 and a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtract 0 from 37 to get 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 50

Advancing to step 5:
When dividing 370 by 50, we get 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 707.0
If we take 350 away from 370, we end up with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 50

Step 6:
50 can be fit into 200 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 7074.0
The remainder is 0 after subtracting 200 from 200.
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 7:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7074.0
If we take 0 away from 0, we end up 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 8:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7074.0
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 7074.0, with a leftover of 0.0.
