27928021 divided by 526 
The aim is to understand the frequency of 526 in 27928021.

On to step 1:
If we divide 2 by 526, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 526

Moving on to step 2:
526 can be fit into 27 0 times, resulting in a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 526

Let's proceed to step 3:
The number 526 fits into 279 0 times, leaving a remainder of 279.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 279, we get 279.
Take the next digit (2) from the dividend and append it to 279, then repeat: 2792 / 526

Advancing to step 4:
2792 divided by 526 is 5 with a remainder of 162.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 2630 from 2792 and we're left with 162.
Fetch the next digit (8) from the dividend, attach it to 162 and continue: 1628 / 526

On to step 5:
When dividing 1628 by 526, we get 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we subtract 1578 from 1628, we get 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 526

On to step 6:
526 can be fit into 500 0 times, resulting in a remainder of 500.
Use 0 as the next digit of our solution. 
Result so far: 530.0
Deduct 0 from 500 and we're left with 500.
Include the next digit (2) from the dividend after 500, then repeat: 5002 / 526

On to step 7:
The number 526 fits into 5002 9 times, leaving a remainder of 268.
Record the quotient 9 as the next digit in the result. 
Result so far: 5309.0
Deduct 4734 from 5002 and we're left with 268.
Include the next digit (1) from the dividend after 268, then repeat: 2681 / 526

On to step 8:
526 can be fit into 2681 5 times, resulting in a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 53095.0
If we subtract 2630 from 2681, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 9:
When dividing 510 by 526, we get 0 with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 53095.0
Deduct 0 from 510 and we're left with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 10:
526 goes into 5100 9 times with a remainder of 366.
Record the quotient 9 as the next digit in the result. 
Result so far: 53095.09
Deduct 4734 from 5100 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 11:
526 can be fit into 3660 6 times, resulting in a remainder of 504.
Put 6 as the next digit of the answer. 
Result so far: 53095.096
If we take 3156 away from 3660, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Step 12:
The number 526 fits into 5040 9 times, leaving a remainder of 306.
Record the quotient 9 as the next digit in the result. 
Result so far: 53095.0969
Subtract 4734 from 5040 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 13:
If we divide 3060 by 526, we get 5 and a remainder of 430.
Record the quotient 5 as the next digit in the result. 
Result so far: 53095.09695
If we take 2630 away from 3060, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 14:
The number 526 fits into 4300 8 times, leaving a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 53095.096958
Deduct 4208 from 4300 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 15:
920 divided by 526 is 1 with a remainder of 394.
The number 1 becomes the next digit in our result. 
Result so far: 53095.0969581
If we take 526 away from 920, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 16:
526 can be fit into 3940 7 times, resulting in a remainder of 258.
Use 7 as the next digit of our solution. 
Result so far: 53095.09695817
Deduct 3682 from 3940 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The quotient of the division is 53095.09695817, and the remainder is 2.58e-07.
