54935987 divided by 857 
The aim is to understand the frequency of 857 in 54935987.

Moving on to step 1:
857 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 857

Moving on to step 2:
The number 857 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 857

Let's proceed to step 3:
If we divide 549 by 857, we get 0 and a remainder of 549.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 549 leaves us with 549.
Include the next digit (3) from the dividend after 549, then repeat: 5493 / 857

Moving on to step 4:
The number 857 fits into 5493 6 times, leaving a remainder of 351.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5142 away from 5493, we end up with 351.
Fetch the next digit (5) from the dividend, attach it to 351 and continue: 3515 / 857

Moving on to step 5:
When dividing 3515 by 857, we get 4 with a remainder of 87.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
If we subtract 3428 from 3515, we get 87.
Bring next digit (9) of the dividend behind the 87 and repeat the process: 879 / 857

Going ahead to step 6:
When dividing 879 by 857, we get 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 641.0
Subtracting 857 from 879 leaves us with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 857

On to step 7:
The number 857 fits into 228 0 times, leaving a remainder of 228.
The next digit of our result is 0. 
Result so far: 6410.0
Deduct 0 from 228 and we're left with 228.
Bring next digit (7) of the dividend behind the 228 and repeat the process: 2287 / 857

Advancing to step 8:
When dividing 2287 by 857, we get 2 with a remainder of 573.
The next digit of our result is 2. 
Result so far: 64102.0
The remainder is 573 after subtracting 1714 from 2287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Let's proceed to step 9:
If we divide 5730 by 857, we get 6 and a remainder of 588.
Use 6 as the next digit of our solution. 
Result so far: 64102.6
If we take 5142 away from 5730, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Advancing to step 10:
The number 857 fits into 5880 6 times, leaving a remainder of 738.
The number 6 becomes the next digit in our result. 
Result so far: 64102.66
Deduct 5142 from 5880 and we're left with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

The quotient of the division is 64102.66, and the remainder is 0.738.
