We divide 70561943 by 50
The aim is to understand the frequency of 50 in 70561943.

Let's proceed to step 1:
50 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 50

Going ahead to step 2:
The number 50 fits into 70 1 times, leaving a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 50 from 70, we get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 50

Let's proceed to step 3:
50 goes into 205 4 times with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 200 from 205, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 50

Going ahead to step 4:
50 goes into 56 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 141.0
Subtract 50 from 56 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 50

Let's proceed to step 5:
50 goes into 61 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1411.0
Subtract 50 from 61 to get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 50

Step 6:
50 can be fit into 119 2 times, resulting in a remainder of 19.
The next digit of our result is 2. 
Result so far: 14112.0
If we take 100 away from 119, we end up with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 50

Moving on to step 7:
When dividing 194 by 50, we get 3 with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 141123.0
The remainder is 44 after subtracting 150 from 194.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 50

Advancing to step 8:
50 can be fit into 443 8 times, resulting in a remainder of 43.
The number 8 becomes the next digit in our result. 
Result so far: 1411238.0
Subtracting 400 from 443 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
430 divided by 50 is 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 1411238.8
Deduct 400 from 430 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
When dividing 300 by 50, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 1411238.86
If we take 300 away from 300, 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.

Going ahead to step 11:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1411238.86
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.

Advancing to step 12:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 1411238.86
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.

After the division, we end up with 1411238.86 and a remainder of 0.0.
