47177001 ÷ 866 
The aim is to understand the frequency of 866 in 47177001.

Step 1:
When dividing 4 by 866, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 866

Step 2:
The number 866 fits into 47 0 times, leaving a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 866

Step 3:
866 goes into 471 0 times with a remainder of 471.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 471 leaves us with 471.
Append the next digit (7) from the dividend to 471 and continue with: 4717 / 866

Moving on to step 4:
866 can be fit into 4717 5 times, resulting in a remainder of 387.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 4330 from 4717 and we're left with 387.
Append the next digit (7) from the dividend to 387 and continue with: 3877 / 866

On to step 5:
If we divide 3877 by 866, we get 4 and a remainder of 413.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Subtracting 3464 from 3877 leaves us with 413.
Include the next digit (0) from the dividend after 413, then repeat: 4130 / 866

Moving on to step 6:
866 goes into 4130 4 times with a remainder of 666.
The next digit of our result is 4. 
Result so far: 544.0
Subtract 3464 from 4130 to get 666.
Fetch the next digit (0) from the dividend, attach it to 666 and continue: 6660 / 866

Let's proceed to step 7:
866 goes into 6660 7 times with a remainder of 598.
Write down 7 as next digit of the result. 
Result so far: 5447.0
The remainder is 598 after subtracting 6062 from 6660.
Fetch the next digit (1) from the dividend, attach it to 598 and continue: 5981 / 866

Advancing to step 8:
When dividing 5981 by 866, we get 6 with a remainder of 785.
Record the quotient 6 as the next digit in the result. 
Result so far: 54476.0
Subtracting 5196 from 5981 leaves us with 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Going ahead to step 9:
The number 866 fits into 7850 9 times, leaving a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 54476.9
Deduct 7794 from 7850 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
866 goes into 560 0 times with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 54476.9
Subtracting 0 from 560 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 11:
866 can be fit into 5600 6 times, resulting in a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 54476.906
Deduct 5196 from 5600 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 12:
866 can be fit into 4040 4 times, resulting in a remainder of 576.
Put 4 as the next digit of the answer. 
Result so far: 54476.9064
Subtracting 3464 from 4040 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Advancing to step 13:
866 goes into 5760 6 times with a remainder of 564.
Use 6 as the next digit of our solution. 
Result so far: 54476.90646
The remainder is 564 after subtracting 5196 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 14:
866 can be fit into 5640 6 times, resulting in a remainder of 444.
The number 6 becomes the next digit in our result. 
Result so far: 54476.906466
If we take 5196 away from 5640, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

The final result is 54476.906466 with a remainder of 4.44e-05.
