74666631 ÷ 756 
The aim is to understand the frequency of 756 in 74666631.

On to step 1:
756 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 756

Let's proceed to step 2:
If we divide 74 by 756, we get 0 and a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 756

Advancing to step 3:
756 can be fit into 746 0 times, resulting in a remainder of 746.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 746 after subtracting 0 from 746.
Include the next digit (6) from the dividend after 746, then repeat: 7466 / 756

Moving on to step 4:
756 goes into 7466 9 times with a remainder of 662.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 6804 from 7466, we get 662.
Grab the next digit (6) from the dividend, add it to 662, then carry on: 6626 / 756

Moving on to step 5:
756 goes into 6626 8 times with a remainder of 578.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtracting 6048 from 6626 leaves us with 578.
Include the next digit (6) from the dividend after 578, then repeat: 5786 / 756

Going ahead to step 6:
If we divide 5786 by 756, we get 7 and a remainder of 494.
Put 7 as the next digit of the answer. 
Result so far: 987.0
Subtract 5292 from 5786 to get 494.
Bring next digit (3) of the dividend behind the 494 and repeat the process: 4943 / 756

Step 7:
4943 divided by 756 is 6 with a remainder of 407.
Write down 6 as next digit of the result. 
Result so far: 9876.0
The remainder is 407 after subtracting 4536 from 4943.
Take the next digit (1) from the dividend and append it to 407, then repeat: 4071 / 756

Let's proceed to step 8:
When dividing 4071 by 756, we get 5 with a remainder of 291.
The next digit of our result is 5. 
Result so far: 98765.0
If we take 3780 away from 4071, we end up with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 9:
The number 756 fits into 2910 3 times, leaving a remainder of 642.
The number 3 becomes the next digit in our result. 
Result so far: 98765.3
Subtracting 2268 from 2910 leaves us with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Going ahead to step 10:
756 can be fit into 6420 8 times, resulting in a remainder of 372.
Use 8 as the next digit of our solution. 
Result so far: 98765.38
The remainder is 372 after subtracting 6048 from 6420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 11:
756 goes into 3720 4 times with a remainder of 696.
The next digit of our result is 4. 
Result so far: 98765.384
Subtracting 3024 from 3720 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 12:
When dividing 6960 by 756, we get 9 with a remainder of 156.
Write down 9 as next digit of the result. 
Result so far: 98765.3849
The remainder is 156 after subtracting 6804 from 6960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 13:
If we divide 1560 by 756, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 98765.38492
Subtracting 1512 from 1560 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
If we divide 480 by 756, we get 0 and a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 98765.38492
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 15:
When dividing 4800 by 756, we get 6 with a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 98765.3849206
The remainder is 264 after subtracting 4536 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 16:
The number 756 fits into 2640 3 times, leaving a remainder of 372.
The number 3 becomes the next digit in our result. 
Result so far: 98765.38492063
Deduct 2268 from 2640 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

After the division, we end up with 98765.38492063 and a remainder of 3.72e-07.
