81357150 ÷ 886 
The aim is to understand the frequency of 886 in 81357150.

Advancing to step 1:
When dividing 8 by 886, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 886

Going ahead to step 2:
When dividing 81 by 886, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 886

Let's proceed to step 3:
If we divide 813 by 886, we get 0 and a remainder of 813.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 813 and we're left with 813.
Bring next digit (5) of the dividend behind the 813 and repeat the process: 8135 / 886

Going ahead to step 4:
If we divide 8135 by 886, we get 9 and a remainder of 161.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 7974 from 8135 leaves us with 161.
Take the next digit (7) from the dividend and append it to 161, then repeat: 1617 / 886

Going ahead to step 5:
886 goes into 1617 1 times with a remainder of 731.
The next digit of our result is 1. 
Result so far: 91.0
Deduct 886 from 1617 and we're left with 731.
Take the next digit (1) from the dividend and append it to 731, then repeat: 7311 / 886

Going ahead to step 6:
The number 886 fits into 7311 8 times, leaving a remainder of 223.
Use 8 as the next digit of our solution. 
Result so far: 918.0
Subtracting 7088 from 7311 leaves us with 223.
Bring next digit (5) of the dividend behind the 223 and repeat the process: 2235 / 886

Going ahead to step 7:
When dividing 2235 by 886, we get 2 with a remainder of 463.
Write down 2 as next digit of the result. 
Result so far: 9182.0
Deduct 1772 from 2235 and we're left with 463.
Append the next digit (0) from the dividend to 463 and continue with: 4630 / 886

On to step 8:
If we divide 4630 by 886, we get 5 and a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 91825.0
Deduct 4430 from 4630 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 9:
If we divide 2000 by 886, we get 2 and a remainder of 228.
The number 2 becomes the next digit in our result. 
Result so far: 91825.2
The remainder is 228 after subtracting 1772 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 10:
If we divide 2280 by 886, we get 2 and a remainder of 508.
Use 2 as the next digit of our solution. 
Result so far: 91825.22
Subtract 1772 from 2280 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

The quotient of the division is 91825.22, and the remainder is 0.508.
