6559217 ÷ 887 
The aim is to understand the frequency of 887 in 6559217.

Step 1:
887 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 887

Advancing to step 2:
If we divide 65 by 887, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 887

Advancing to step 3:
887 goes into 655 0 times with a remainder of 655.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 655 after subtracting 0 from 655.
Append the next digit (9) from the dividend to 655 and continue with: 6559 / 887

Going ahead to step 4:
6559 divided by 887 is 7 with a remainder of 350.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 6209 from 6559 leaves us with 350.
Fetch the next digit (2) from the dividend, attach it to 350 and continue: 3502 / 887

Step 5:
The number 887 fits into 3502 3 times, leaving a remainder of 841.
Use 3 as the next digit of our solution. 
Result so far: 73.0
Subtracting 2661 from 3502 leaves us with 841.
Fetch the next digit (1) from the dividend, attach it to 841 and continue: 8411 / 887

Advancing to step 6:
When dividing 8411 by 887, we get 9 with a remainder of 428.
The next digit of our result is 9. 
Result so far: 739.0
Subtract 7983 from 8411 to get 428.
Take the next digit (7) from the dividend and append it to 428, then repeat: 4287 / 887

Step 7:
The number 887 fits into 4287 4 times, leaving a remainder of 739.
Record the quotient 4 as the next digit in the result. 
Result so far: 7394.0
Subtract 3548 from 4287 to get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Moving on to step 8:
If we divide 7390 by 887, we get 8 and a remainder of 294.
Use 8 as the next digit of our solution. 
Result so far: 7394.8
Subtracting 7096 from 7390 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 9:
887 can be fit into 2940 3 times, resulting in a remainder of 279.
Use 3 as the next digit of our solution. 
Result so far: 7394.83
Subtract 2661 from 2940 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 10:
If we divide 2790 by 887, we get 3 and a remainder of 129.
The number 3 becomes the next digit in our result. 
Result so far: 7394.833
The remainder is 129 after subtracting 2661 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final outcome is 7394.833, with a leftover of 0.0129.
