66402055 ÷ 887 
The aim is to understand the frequency of 887 in 66402055.

Moving on to step 1:
6 divided by 887 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 887

On to step 2:
When dividing 66 by 887, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 887

Advancing to step 3:
When dividing 664 by 887, we get 0 with a remainder of 664.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 664, we get 664.
Append the next digit (0) from the dividend to 664 and continue with: 6640 / 887

Let's proceed to step 4:
887 goes into 6640 7 times with a remainder of 431.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 6209 from 6640 leaves us with 431.
Bring next digit (2) of the dividend behind the 431 and repeat the process: 4312 / 887

Going ahead to step 5:
4312 divided by 887 is 4 with a remainder of 764.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we subtract 3548 from 4312, we get 764.
Take the next digit (0) from the dividend and append it to 764, then repeat: 7640 / 887

Going ahead to step 6:
If we divide 7640 by 887, we get 8 and a remainder of 544.
Use 8 as the next digit of our solution. 
Result so far: 748.0
Subtracting 7096 from 7640 leaves us with 544.
Take the next digit (5) from the dividend and append it to 544, then repeat: 5445 / 887

Step 7:
887 goes into 5445 6 times with a remainder of 123.
Use 6 as the next digit of our solution. 
Result so far: 7486.0
If we take 5322 away from 5445, we end up with 123.
Append the next digit (5) from the dividend to 123 and continue with: 1235 / 887

Step 8:
When dividing 1235 by 887, we get 1 with a remainder of 348.
The next digit of our result is 1. 
Result so far: 74861.0
Subtract 887 from 1235 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 9:
If we divide 3480 by 887, we get 3 and a remainder of 819.
Put 3 as the next digit of the answer. 
Result so far: 74861.3
Deduct 2661 from 3480 and we're left with 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

Going ahead to step 10:
When dividing 8190 by 887, we get 9 with a remainder of 207.
The next digit of our result is 9. 
Result so far: 74861.39
If we subtract 7983 from 8190, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 11:
If we divide 2070 by 887, we get 2 and a remainder of 296.
Put 2 as the next digit of the answer. 
Result so far: 74861.392
The remainder is 296 after subtracting 1774 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 12:
When dividing 2960 by 887, we get 3 with a remainder of 299.
The next digit of our result is 3. 
Result so far: 74861.3923
Subtracting 2661 from 2960 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Let's proceed to step 13:
887 goes into 2990 3 times with a remainder of 329.
Record the quotient 3 as the next digit in the result. 
Result so far: 74861.39233
Subtracting 2661 from 2990 leaves us with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Our division results in 74861.39233 with a remaining 0.000329.
