We look at the division of 20875192 by 748 
The aim is to understand the frequency of 748 in 20875192.

Advancing to step 1:
2 divided by 748 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 748

Advancing to step 2:
748 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 748

Let's proceed to step 3:
If we divide 208 by 748, we get 0 and a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 208, we get 208.
Include the next digit (7) from the dividend after 208, then repeat: 2087 / 748

Advancing to step 4:
If we divide 2087 by 748, we get 2 and a remainder of 591.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1496 away from 2087, we end up with 591.
Include the next digit (5) from the dividend after 591, then repeat: 5915 / 748

Going ahead to step 5:
5915 divided by 748 is 7 with a remainder of 679.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 679 after subtracting 5236 from 5915.
Bring next digit (1) of the dividend behind the 679 and repeat the process: 6791 / 748

Let's proceed to step 6:
When dividing 6791 by 748, we get 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 279.0
Deduct 6732 from 6791 and we're left with 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 748

Let's proceed to step 7:
When dividing 599 by 748, we get 0 with a remainder of 599.
Write down 0 as next digit of the result. 
Result so far: 2790.0
If we take 0 away from 599, we end up with 599.
Append the next digit (2) from the dividend to 599 and continue with: 5992 / 748

On to step 8:
If we divide 5992 by 748, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 27908.0
Deduct 5984 from 5992 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
The number 748 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 27908.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
748 can be fit into 800 1 times, resulting in a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 27908.01
Subtracting 748 from 800 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
520 divided by 748 is 0 with a remainder of 520.
The next digit of our result is 0. 
Result so far: 27908.01
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Going ahead to step 12:
748 can be fit into 5200 6 times, resulting in a remainder of 712.
Put 6 as the next digit of the answer. 
Result so far: 27908.0106
If we take 4488 away from 5200, we end up with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Step 13:
748 can be fit into 7120 9 times, resulting in a remainder of 388.
Record the quotient 9 as the next digit in the result. 
Result so far: 27908.01069
Subtract 6732 from 7120 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 14:
748 goes into 3880 5 times with a remainder of 140.
The next digit of our result is 5. 
Result so far: 27908.010695
If we take 3740 away from 3880, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
748 can be fit into 1400 1 times, resulting in a remainder of 652.
The next digit of our result is 1. 
Result so far: 27908.0106951
Deduct 748 from 1400 and we're left with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Advancing to step 16:
The number 748 fits into 6520 8 times, leaving a remainder of 536.
Put 8 as the next digit of the answer. 
Result so far: 27908.01069518
Deduct 5984 from 6520 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

In conclusion, the division gives 27908.01069518 with a balance of 5.36e-07.
