50555215 ÷ 851 
The aim is to understand the frequency of 851 in 50555215.

Step 1:
5 divided by 851 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 851

On to step 2:
50 divided by 851 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 851

Let's proceed to step 3:
When dividing 505 by 851, we get 0 with a remainder of 505.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 505, we end up with 505.
Fetch the next digit (5) from the dividend, attach it to 505 and continue: 5055 / 851

On to step 4:
851 can be fit into 5055 5 times, resulting in a remainder of 800.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 4255 away from 5055, we end up with 800.
Append the next digit (5) from the dividend to 800 and continue with: 8005 / 851

Moving on to step 5:
When dividing 8005 by 851, we get 9 with a remainder of 346.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
If we subtract 7659 from 8005, we get 346.
Bring next digit (2) of the dividend behind the 346 and repeat the process: 3462 / 851

Moving on to step 6:
851 can be fit into 3462 4 times, resulting in a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 594.0
The remainder is 58 after subtracting 3404 from 3462.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 851

Going ahead to step 7:
The number 851 fits into 581 0 times, leaving a remainder of 581.
The next digit of our result is 0. 
Result so far: 5940.0
The remainder is 581 after subtracting 0 from 581.
Take the next digit (5) from the dividend and append it to 581, then repeat: 5815 / 851

Advancing to step 8:
5815 divided by 851 is 6 with a remainder of 709.
The number 6 becomes the next digit in our result. 
Result so far: 59406.0
If we take 5106 away from 5815, we end up with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Advancing to step 9:
851 goes into 7090 8 times with a remainder of 282.
The number 8 becomes the next digit in our result. 
Result so far: 59406.8
If we take 6808 away from 7090, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 10:
When dividing 2820 by 851, we get 3 with a remainder of 267.
Write down 3 as next digit of the result. 
Result so far: 59406.83
Subtract 2553 from 2820 to get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Advancing to step 11:
851 goes into 2670 3 times with a remainder of 117.
Put 3 as the next digit of the answer. 
Result so far: 59406.833
If we take 2553 away from 2670, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

In conclusion, the division gives 59406.833 with a balance of 0.0117.
