10500749 divided by 747 
The aim is to understand the frequency of 747 in 10500749.

Advancing to step 1:
If we divide 1 by 747, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 747

Going ahead to step 2:
747 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 747

Going ahead to step 3:
747 goes into 105 0 times with a remainder of 105.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 105, we end up with 105.
Fetch the next digit (0) from the dividend, attach it to 105 and continue: 1050 / 747

Step 4:
The number 747 fits into 1050 1 times, leaving a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 747 from 1050, we get 303.
Grab the next digit (0) from the dividend, add it to 303, then carry on: 3030 / 747

Advancing to step 5:
747 goes into 3030 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 2988 from 3030 and we're left with 42.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 747

Going ahead to step 6:
427 divided by 747 is 0 with a remainder of 427.
Write down 0 as next digit of the result. 
Result so far: 140.0
The remainder is 427 after subtracting 0 from 427.
Include the next digit (4) from the dividend after 427, then repeat: 4274 / 747

Let's proceed to step 7:
The number 747 fits into 4274 5 times, leaving a remainder of 539.
The number 5 becomes the next digit in our result. 
Result so far: 1405.0
Subtract 3735 from 4274 to get 539.
Take the next digit (9) from the dividend and append it to 539, then repeat: 5399 / 747

On to step 8:
The number 747 fits into 5399 7 times, leaving a remainder of 170.
Write down 7 as next digit of the result. 
Result so far: 14057.0
If we take 5229 away from 5399, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 9:
If we divide 1700 by 747, we get 2 and a remainder of 206.
The number 2 becomes the next digit in our result. 
Result so far: 14057.2
The remainder is 206 after subtracting 1494 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 10:
When dividing 2060 by 747, we get 2 with a remainder of 566.
The number 2 becomes the next digit in our result. 
Result so far: 14057.22
If we take 1494 away from 2060, we end up with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

The final result is 14057.22 with a remainder of 0.566.
