We're dividing 80102565 by 749 
The aim is to understand the frequency of 749 in 80102565.

On to step 1:
749 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 749

Moving on to step 2:
80 divided by 749 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 749

On to step 3:
When dividing 801 by 749, we get 1 with a remainder of 52.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 749 from 801, we get 52.
Take the next digit (0) from the dividend and append it to 52, then repeat: 520 / 749

On to step 4:
The number 749 fits into 520 0 times, leaving a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 520 to get 520.
Append the next digit (2) from the dividend to 520 and continue with: 5202 / 749

Advancing to step 5:
5202 divided by 749 is 6 with a remainder of 708.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Subtracting 4494 from 5202 leaves us with 708.
Append the next digit (5) from the dividend to 708 and continue with: 7085 / 749

Step 6:
7085 divided by 749 is 9 with a remainder of 344.
Record the quotient 9 as the next digit in the result. 
Result so far: 1069.0
If we take 6741 away from 7085, we end up with 344.
Grab the next digit (6) from the dividend, add it to 344, then carry on: 3446 / 749

Moving on to step 7:
When dividing 3446 by 749, we get 4 with a remainder of 450.
Record the quotient 4 as the next digit in the result. 
Result so far: 10694.0
Deduct 2996 from 3446 and we're left with 450.
Include the next digit (5) from the dividend after 450, then repeat: 4505 / 749

Step 8:
4505 divided by 749 is 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 106946.0
Subtract 4494 from 4505 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
If we divide 110 by 749, we get 0 and a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 106946.0
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
1100 divided by 749 is 1 with a remainder of 351.
Record the quotient 1 as the next digit in the result. 
Result so far: 106946.01
Deduct 749 from 1100 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 11:
When dividing 3510 by 749, we get 4 with a remainder of 514.
Write down 4 as next digit of the result. 
Result so far: 106946.014
Subtracting 2996 from 3510 leaves us with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Let's proceed to step 12:
When dividing 5140 by 749, we get 6 with a remainder of 646.
Put 6 as the next digit of the answer. 
Result so far: 106946.0146
The remainder is 646 after subtracting 4494 from 5140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Advancing to step 13:
If we divide 6460 by 749, we get 8 and a remainder of 468.
Record the quotient 8 as the next digit in the result. 
Result so far: 106946.01468
Subtract 5992 from 6460 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 14:
If we divide 4680 by 749, we get 6 and a remainder of 186.
The number 6 becomes the next digit in our result. 
Result so far: 106946.014686
If we take 4494 away from 4680, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 15:
1860 divided by 749 is 2 with a remainder of 362.
The number 2 becomes the next digit in our result. 
Result so far: 106946.0146862
Deduct 1498 from 1860 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Moving on to step 16:
3620 divided by 749 is 4 with a remainder of 624.
Record the quotient 4 as the next digit in the result. 
Result so far: 106946.01468624
The remainder is 624 after subtracting 2996 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

The final outcome is 106946.01468624, with a leftover of 6.24e-07.
