6658366 ÷ 868 
The aim is to understand the frequency of 868 in 6658366.

On to step 1:
868 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 868

On to step 2:
When dividing 66 by 868, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 868

Going ahead to step 3:
868 can be fit into 665 0 times, resulting in a remainder of 665.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 665 and we're left with 665.
Append the next digit (8) from the dividend to 665 and continue with: 6658 / 868

Let's proceed to step 4:
When dividing 6658 by 868, we get 7 with a remainder of 582.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 6076 from 6658 leaves us with 582.
Append the next digit (3) from the dividend to 582 and continue with: 5823 / 868

Step 5:
If we divide 5823 by 868, we get 6 and a remainder of 615.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Subtract 5208 from 5823 to get 615.
Include the next digit (6) from the dividend after 615, then repeat: 6156 / 868

Advancing to step 6:
When dividing 6156 by 868, we get 7 with a remainder of 80.
Record the quotient 7 as the next digit in the result. 
Result so far: 767.0
If we subtract 6076 from 6156, we get 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 868

Moving on to step 7:
If we divide 806 by 868, we get 0 and a remainder of 806.
Use 0 as the next digit of our solution. 
Result so far: 7670.0
If we subtract 0 from 806, we get 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Step 8:
If we divide 8060 by 868, we get 9 and a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 7670.9
The remainder is 248 after subtracting 7812 from 8060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 9:
When dividing 2480 by 868, we get 2 with a remainder of 744.
Write down 2 as next digit of the result. 
Result so far: 7670.92
If we subtract 1736 from 2480, we get 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 10:
868 can be fit into 7440 8 times, resulting in a remainder of 496.
The next digit of our result is 8. 
Result so far: 7670.928
If we take 6944 away from 7440, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 11:
868 goes into 4960 5 times with a remainder of 620.
Use 5 as the next digit of our solution. 
Result so far: 7670.9285
Subtract 4340 from 4960 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 12:
If we divide 6200 by 868, we get 7 and a remainder of 124.
Put 7 as the next digit of the answer. 
Result so far: 7670.92857
If we subtract 6076 from 6200, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 13:
The number 868 fits into 1240 1 times, leaving a remainder of 372.
The next digit of our result is 1. 
Result so far: 7670.928571
The remainder is 372 after subtracting 868 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Advancing to step 14:
When dividing 3720 by 868, we get 4 with a remainder of 248.
Write down 4 as next digit of the result. 
Result so far: 7670.9285714
Subtracting 3472 from 3720 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 15:
The number 868 fits into 2480 2 times, leaving a remainder of 744.
Put 2 as the next digit of the answer. 
Result so far: 7670.92857142
Subtracting 1736 from 2480 leaves us with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

The final outcome is 7670.92857142, with a leftover of 7.44e-07.
