We look at the division of 15563056 by 857 
The aim is to understand the frequency of 857 in 15563056.

Step 1:
857 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 857

Let's proceed to step 2:
15 divided by 857 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 857

Moving on to step 3:
857 goes into 155 0 times with a remainder of 155.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 155 to get 155.
Fetch the next digit (6) from the dividend, attach it to 155 and continue: 1556 / 857

Let's proceed to step 4:
When dividing 1556 by 857, we get 1 with a remainder of 699.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 857 from 1556 leaves us with 699.
Bring next digit (3) of the dividend behind the 699 and repeat the process: 6993 / 857

Moving on to step 5:
The number 857 fits into 6993 8 times, leaving a remainder of 137.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 137 after subtracting 6856 from 6993.
Grab the next digit (0) from the dividend, add it to 137, then carry on: 1370 / 857

On to step 6:
857 can be fit into 1370 1 times, resulting in a remainder of 513.
Use 1 as the next digit of our solution. 
Result so far: 181.0
The remainder is 513 after subtracting 857 from 1370.
Append the next digit (5) from the dividend to 513 and continue with: 5135 / 857

On to step 7:
5135 divided by 857 is 5 with a remainder of 850.
Put 5 as the next digit of the answer. 
Result so far: 1815.0
If we take 4285 away from 5135, we end up with 850.
Fetch the next digit (6) from the dividend, attach it to 850 and continue: 8506 / 857

Moving on to step 8:
If we divide 8506 by 857, we get 9 and a remainder of 793.
Use 9 as the next digit of our solution. 
Result so far: 18159.0
Deduct 7713 from 8506 and we're left with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Going ahead to step 9:
857 can be fit into 7930 9 times, resulting in a remainder of 217.
The next digit of our result is 9. 
Result so far: 18159.9
Subtracting 7713 from 7930 leaves us with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Going ahead to step 10:
857 can be fit into 2170 2 times, resulting in a remainder of 456.
Write down 2 as next digit of the result. 
Result so far: 18159.92
Deduct 1714 from 2170 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 11:
857 can be fit into 4560 5 times, resulting in a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 18159.925
If we subtract 4285 from 4560, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 12:
857 goes into 2750 3 times with a remainder of 179.
The next digit of our result is 3. 
Result so far: 18159.9253
If we subtract 2571 from 2750, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 13:
1790 divided by 857 is 2 with a remainder of 76.
The next digit of our result is 2. 
Result so far: 18159.92532
If we subtract 1714 from 1790, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
The number 857 fits into 760 0 times, leaving a remainder of 760.
Put 0 as the next digit of the answer. 
Result so far: 18159.92532
If we subtract 0 from 760, we get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 15:
When dividing 7600 by 857, we get 8 with a remainder of 744.
Record the quotient 8 as the next digit in the result. 
Result so far: 18159.9253208
If we subtract 6856 from 7600, we get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 16:
857 can be fit into 7440 8 times, resulting in a remainder of 584.
Put 8 as the next digit of the answer. 
Result so far: 18159.92532088
Subtracting 6856 from 7440 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

The quotient of the division is 18159.92532088, and the remainder is 5.84e-07.
