We look at the division of 22257640 by 748 
The aim is to understand the frequency of 748 in 22257640.

Let's proceed to step 1:
748 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 748

Step 2:
The number 748 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 748

Going ahead to step 3:
If we divide 222 by 748, we get 0 and a remainder of 222.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 222 after subtracting 0 from 222.
Append the next digit (5) from the dividend to 222 and continue with: 2225 / 748

Going ahead to step 4:
2225 divided by 748 is 2 with a remainder of 729.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1496 from 2225, we get 729.
Include the next digit (7) from the dividend after 729, then repeat: 7297 / 748

Let's proceed to step 5:
If we divide 7297 by 748, we get 9 and a remainder of 565.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 565 after subtracting 6732 from 7297.
Include the next digit (6) from the dividend after 565, then repeat: 5656 / 748

Going ahead to step 6:
The number 748 fits into 5656 7 times, leaving a remainder of 420.
Use 7 as the next digit of our solution. 
Result so far: 297.0
If we take 5236 away from 5656, we end up with 420.
Take the next digit (4) from the dividend and append it to 420, then repeat: 4204 / 748

Let's proceed to step 7:
748 goes into 4204 5 times with a remainder of 464.
Use 5 as the next digit of our solution. 
Result so far: 2975.0
If we take 3740 away from 4204, we end up with 464.
Append the next digit (0) from the dividend to 464 and continue with: 4640 / 748

On to step 8:
If we divide 4640 by 748, we get 6 and a remainder of 152.
Record the quotient 6 as the next digit in the result. 
Result so far: 29756.0
Deduct 4488 from 4640 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 9:
1520 divided by 748 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 29756.2
If we subtract 1496 from 1520, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
748 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 29756.2
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 11:
748 goes into 2400 3 times with a remainder of 156.
Use 3 as the next digit of our solution. 
Result so far: 29756.203
The remainder is 156 after subtracting 2244 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 12:
When dividing 1560 by 748, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 29756.2032
Deduct 1496 from 1560 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
If we divide 640 by 748, we get 0 and a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 29756.2032
If we take 0 away from 640, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 14:
748 goes into 6400 8 times with a remainder of 416.
Write down 8 as next digit of the result. 
Result so far: 29756.203208
If we subtract 5984 from 6400, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 15:
748 goes into 4160 5 times with a remainder of 420.
Record the quotient 5 as the next digit in the result. 
Result so far: 29756.2032085
If we subtract 3740 from 4160, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 16:
748 can be fit into 4200 5 times, resulting in a remainder of 460.
The next digit of our result is 5. 
Result so far: 29756.20320855
If we subtract 3740 from 4200, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

The quotient of the division is 29756.20320855, and the remainder is 4.6e-07.
