Let's divide 81862981 by 528
The aim is to understand the frequency of 528 in 81862981.

Moving on to step 1:
528 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 528

Let's proceed to step 2:
81 divided by 528 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 528

Moving on to step 3:
The number 528 fits into 818 1 times, leaving a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 528 from 818 to get 290.
Grab the next digit (6) from the dividend, add it to 290, then carry on: 2906 / 528

Moving on to step 4:
528 goes into 2906 5 times with a remainder of 266.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 266 after subtracting 2640 from 2906.
Grab the next digit (2) from the dividend, add it to 266, then carry on: 2662 / 528

Let's proceed to step 5:
528 can be fit into 2662 5 times, resulting in a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 155.0
If we take 2640 away from 2662, we end up with 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 528

Advancing to step 6:
229 divided by 528 is 0 with a remainder of 229.
Put 0 as the next digit of the answer. 
Result so far: 1550.0
Subtract 0 from 229 to get 229.
Take the next digit (8) from the dividend and append it to 229, then repeat: 2298 / 528

Moving on to step 7:
2298 divided by 528 is 4 with a remainder of 186.
The number 4 becomes the next digit in our result. 
Result so far: 15504.0
Deduct 2112 from 2298 and we're left with 186.
Take the next digit (1) from the dividend and append it to 186, then repeat: 1861 / 528

Step 8:
528 goes into 1861 3 times with a remainder of 277.
The number 3 becomes the next digit in our result. 
Result so far: 155043.0
The remainder is 277 after subtracting 1584 from 1861.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Advancing to step 9:
If we divide 2770 by 528, we get 5 and a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 155043.5
Deduct 2640 from 2770 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 10:
If we divide 1300 by 528, we get 2 and a remainder of 244.
Put 2 as the next digit of the answer. 
Result so far: 155043.52
Subtracting 1056 from 1300 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 11:
The number 528 fits into 2440 4 times, leaving a remainder of 328.
Put 4 as the next digit of the answer. 
Result so far: 155043.524
Deduct 2112 from 2440 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 12:
When dividing 3280 by 528, we get 6 with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 155043.5246
Deduct 3168 from 3280 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 13:
528 can be fit into 1120 2 times, resulting in a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 155043.52462
If we take 1056 away from 1120, we end up 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.

Let's proceed to step 14:
528 can be fit into 640 1 times, resulting in a remainder of 112.
The number 1 becomes the next digit in our result. 
Result so far: 155043.524621
Deduct 528 from 640 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
The number 528 fits into 1120 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 155043.5246212
The remainder is 64 after subtracting 1056 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
If we divide 640 by 528, we get 1 and a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 155043.52462121
If we subtract 528 from 640, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

In conclusion, the division gives 155043.52462121 with a balance of 1.12e-07.
