We're dividing 18436613 by 748 
The aim is to understand the frequency of 748 in 18436613.

Moving on to step 1:
When dividing 1 by 748, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 748

Going ahead to step 2:
748 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 748

Let's proceed to step 3:
748 goes into 184 0 times with a remainder of 184.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 184 and we're left with 184.
Grab the next digit (3) from the dividend, add it to 184, then carry on: 1843 / 748

Let's proceed to step 4:
748 can be fit into 1843 2 times, resulting in a remainder of 347.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1496 from 1843 to get 347.
Append the next digit (6) from the dividend to 347 and continue with: 3476 / 748

On to step 5:
When dividing 3476 by 748, we get 4 with a remainder of 484.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 2992 from 3476 to get 484.
Take the next digit (6) from the dividend and append it to 484, then repeat: 4846 / 748

On to step 6:
748 can be fit into 4846 6 times, resulting in a remainder of 358.
The next digit of our result is 6. 
Result so far: 246.0
The remainder is 358 after subtracting 4488 from 4846.
Take the next digit (1) from the dividend and append it to 358, then repeat: 3581 / 748

Going ahead to step 7:
748 goes into 3581 4 times with a remainder of 589.
Write down 4 as next digit of the result. 
Result so far: 2464.0
The remainder is 589 after subtracting 2992 from 3581.
Grab the next digit (3) from the dividend, add it to 589, then carry on: 5893 / 748

Moving on to step 8:
If we divide 5893 by 748, we get 7 and a remainder of 657.
Put 7 as the next digit of the answer. 
Result so far: 24647.0
If we take 5236 away from 5893, we end up with 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Going ahead to step 9:
748 can be fit into 6570 8 times, resulting in a remainder of 586.
Use 8 as the next digit of our solution. 
Result so far: 24647.8
If we subtract 5984 from 6570, we get 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

On to step 10:
If we divide 5860 by 748, we get 7 and a remainder of 624.
Use 7 as the next digit of our solution. 
Result so far: 24647.87
Subtracting 5236 from 5860 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 11:
When dividing 6240 by 748, we get 8 with a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 24647.878
Deduct 5984 from 6240 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 12:
The number 748 fits into 2560 3 times, leaving a remainder of 316.
Record the quotient 3 as the next digit in the result. 
Result so far: 24647.8783
If we take 2244 away from 2560, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 13:
3160 divided by 748 is 4 with a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 24647.87834
If we take 2992 away from 3160, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 14:
748 can be fit into 1680 2 times, resulting in a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 24647.878342
Deduct 1496 from 1680 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 15:
When dividing 1840 by 748, we get 2 with a remainder of 344.
The number 2 becomes the next digit in our result. 
Result so far: 24647.8783422
If we subtract 1496 from 1840, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

After the division, we end up with 24647.8783422 and a remainder of 3.44e-06.
