15128220 divided by 747 
The aim is to understand the frequency of 747 in 15128220.

Going ahead to step 1:
747 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 747

Let's proceed to step 2:
747 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 747

Advancing to step 3:
The number 747 fits into 151 0 times, leaving a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Include the next digit (2) from the dividend after 151, then repeat: 1512 / 747

Step 4:
If we divide 1512 by 747, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1494 from 1512 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 747

Moving on to step 5:
188 divided by 747 is 0 with a remainder of 188.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 188, we get 188.
Fetch the next digit (2) from the dividend, attach it to 188 and continue: 1882 / 747

Moving on to step 6:
747 goes into 1882 2 times with a remainder of 388.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
If we take 1494 away from 1882, we end up with 388.
Take the next digit (2) from the dividend and append it to 388, then repeat: 3882 / 747

On to step 7:
747 can be fit into 3882 5 times, resulting in a remainder of 147.
Write down 5 as next digit of the result. 
Result so far: 2025.0
Deduct 3735 from 3882 and we're left with 147.
Bring next digit (0) of the dividend behind the 147 and repeat the process: 1470 / 747

Going ahead to step 8:
When dividing 1470 by 747, we get 1 with a remainder of 723.
The number 1 becomes the next digit in our result. 
Result so far: 20251.0
Subtract 747 from 1470 to get 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Moving on to step 9:
When dividing 7230 by 747, we get 9 with a remainder of 507.
Put 9 as the next digit of the answer. 
Result so far: 20251.9
Subtracting 6723 from 7230 leaves us with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Step 10:
747 goes into 5070 6 times with a remainder of 588.
The next digit of our result is 6. 
Result so far: 20251.96
The remainder is 588 after subtracting 4482 from 5070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Step 11:
If we divide 5880 by 747, we get 7 and a remainder of 651.
Use 7 as the next digit of our solution. 
Result so far: 20251.967
Deduct 5229 from 5880 and we're left with 651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6510, and continue the process.

Moving on to step 12:
If we divide 6510 by 747, we get 8 and a remainder of 534.
The number 8 becomes the next digit in our result. 
Result so far: 20251.9678
If we subtract 5976 from 6510, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Moving on to step 13:
747 can be fit into 5340 7 times, resulting in a remainder of 111.
The next digit of our result is 7. 
Result so far: 20251.96787
Subtract 5229 from 5340 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 14:
When dividing 1110 by 747, we get 1 with a remainder of 363.
Record the quotient 1 as the next digit in the result. 
Result so far: 20251.967871
Subtracting 747 from 1110 leaves us with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Advancing to step 15:
3630 divided by 747 is 4 with a remainder of 642.
The number 4 becomes the next digit in our result. 
Result so far: 20251.9678714
Subtracting 2988 from 3630 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.

Step 16:
747 can be fit into 6420 8 times, resulting in a remainder of 444.
Record the quotient 8 as the next digit in the result. 
Result so far: 20251.96787148
Subtract 5976 from 6420 to get 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 20251.96787148 with a remainder of 4.44e-07.
