Let's divide 80645601 by 887
The aim is to understand the frequency of 887 in 80645601.

Moving on to step 1:
The number 887 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 887

Going ahead to step 2:
80 divided by 887 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 887

Let's proceed to step 3:
The number 887 fits into 806 0 times, leaving a remainder of 806.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 806 to get 806.
Append the next digit (4) from the dividend to 806 and continue with: 8064 / 887

Step 4:
887 goes into 8064 9 times with a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 81 after subtracting 7983 from 8064.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 887

On to step 5:
815 divided by 887 is 0 with a remainder of 815.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 815 leaves us with 815.
Take the next digit (6) from the dividend and append it to 815, then repeat: 8156 / 887

Advancing to step 6:
When dividing 8156 by 887, we get 9 with a remainder of 173.
The number 9 becomes the next digit in our result. 
Result so far: 909.0
Subtracting 7983 from 8156 leaves us with 173.
Fetch the next digit (0) from the dividend, attach it to 173 and continue: 1730 / 887

On to step 7:
When dividing 1730 by 887, we get 1 with a remainder of 843.
The number 1 becomes the next digit in our result. 
Result so far: 9091.0
If we subtract 887 from 1730, we get 843.
Include the next digit (1) from the dividend after 843, then repeat: 8431 / 887

Going ahead to step 8:
If we divide 8431 by 887, we get 9 and a remainder of 448.
Put 9 as the next digit of the answer. 
Result so far: 90919.0
The remainder is 448 after subtracting 7983 from 8431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 9:
When dividing 4480 by 887, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 90919.5
The remainder is 45 after subtracting 4435 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 10:
If we divide 450 by 887, we get 0 and a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 90919.5
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Step 11:
When dividing 4500 by 887, we get 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 90919.505
If we take 4435 away from 4500, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 12:
887 goes into 650 0 times with a remainder of 650.
Record the quotient 0 as the next digit in the result. 
Result so far: 90919.505
Subtract 0 from 650 to get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 13:
When dividing 6500 by 887, we get 7 with a remainder of 291.
Use 7 as the next digit of our solution. 
Result so far: 90919.50507
Subtract 6209 from 6500 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 14:
The number 887 fits into 2910 3 times, leaving a remainder of 249.
Use 3 as the next digit of our solution. 
Result so far: 90919.505073
The remainder is 249 after subtracting 2661 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 15:
887 goes into 2490 2 times with a remainder of 716.
Write down 2 as next digit of the result. 
Result so far: 90919.5050732
Subtract 1774 from 2490 to get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Moving on to step 16:
The number 887 fits into 7160 8 times, leaving a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 90919.50507328
If we subtract 7096 from 7160, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 90919.50507328, with a leftover of 6.4e-08.
