Let's divide 49980280 by 856
The aim is to understand the frequency of 856 in 49980280.

Advancing to step 1:
If we divide 4 by 856, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 856

On to step 2:
856 can be fit into 49 0 times, resulting in a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 856

Let's proceed to step 3:
499 divided by 856 is 0 with a remainder of 499.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 499 to get 499.
Fetch the next digit (8) from the dividend, attach it to 499 and continue: 4998 / 856

Let's proceed to step 4:
856 goes into 4998 5 times with a remainder of 718.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 4280 from 4998 to get 718.
Fetch the next digit (0) from the dividend, attach it to 718 and continue: 7180 / 856

Let's proceed to step 5:
856 goes into 7180 8 times with a remainder of 332.
The next digit of our result is 8. 
Result so far: 58.0
Subtracting 6848 from 7180 leaves us with 332.
Bring next digit (2) of the dividend behind the 332 and repeat the process: 3322 / 856

On to step 6:
If we divide 3322 by 856, we get 3 and a remainder of 754.
Put 3 as the next digit of the answer. 
Result so far: 583.0
If we subtract 2568 from 3322, we get 754.
Include the next digit (8) from the dividend after 754, then repeat: 7548 / 856

Going ahead to step 7:
If we divide 7548 by 856, we get 8 and a remainder of 700.
Write down 8 as next digit of the result. 
Result so far: 5838.0
The remainder is 700 after subtracting 6848 from 7548.
Take the next digit (0) from the dividend and append it to 700, then repeat: 7000 / 856

Let's proceed to step 8:
When dividing 7000 by 856, we get 8 with a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 58388.0
Subtract 6848 from 7000 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 9:
1520 divided by 856 is 1 with a remainder of 664.
Write down 1 as next digit of the result. 
Result so far: 58388.1
The remainder is 664 after subtracting 856 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Moving on to step 10:
The number 856 fits into 6640 7 times, leaving a remainder of 648.
The next digit of our result is 7. 
Result so far: 58388.17
Subtract 5992 from 6640 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

On to step 11:
The number 856 fits into 6480 7 times, leaving a remainder of 488.
The next digit of our result is 7. 
Result so far: 58388.177
If we subtract 5992 from 6480, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

The final result is 58388.177 with a remainder of 0.0488.
