We're dividing 55210749 by 528 
The aim is to understand the frequency of 528 in 55210749.

Let's proceed to step 1:
5 divided by 528 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 528

Going ahead to step 2:
55 divided by 528 is 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 528

Advancing to step 3:
If we divide 552 by 528, we get 1 and a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 24 after subtracting 528 from 552.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 528

Advancing to step 4:
241 divided by 528 is 0 with a remainder of 241.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 241, we get 241.
Fetch the next digit (0) from the dividend, attach it to 241 and continue: 2410 / 528

Advancing to step 5:
2410 divided by 528 is 4 with a remainder of 298.
Use 4 as the next digit of our solution. 
Result so far: 104.0
The remainder is 298 after subtracting 2112 from 2410.
Bring next digit (7) of the dividend behind the 298 and repeat the process: 2987 / 528

On to step 6:
If we divide 2987 by 528, we get 5 and a remainder of 347.
Put 5 as the next digit of the answer. 
Result so far: 1045.0
Deduct 2640 from 2987 and we're left with 347.
Take the next digit (4) from the dividend and append it to 347, then repeat: 3474 / 528

On to step 7:
The number 528 fits into 3474 6 times, leaving a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 10456.0
If we subtract 3168 from 3474, we get 306.
Take the next digit (9) from the dividend and append it to 306, then repeat: 3069 / 528

On to step 8:
3069 divided by 528 is 5 with a remainder of 429.
The number 5 becomes the next digit in our result. 
Result so far: 104565.0
If we take 2640 away from 3069, we end up with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 9:
If we divide 4290 by 528, we get 8 and a remainder of 66.
The next digit of our result is 8. 
Result so far: 104565.8
Subtracting 4224 from 4290 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 10:
If we divide 660 by 528, we get 1 and a remainder of 132.
Record the quotient 1 as the next digit in the result. 
Result so far: 104565.81
The remainder is 132 after subtracting 528 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 11:
528 can be fit into 1320 2 times, resulting in a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 104565.812
If we subtract 1056 from 1320, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 12:
When dividing 2640 by 528, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 104565.8125
If we take 2640 away from 2640, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
528 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 104565.8125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
0 divided by 528 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 104565.8125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 104565.8125 and a remainder of 0.0.
