Let's divide 87852874 by 526
The aim is to understand the frequency of 526 in 87852874.

Step 1:
The number 526 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 526

Moving on to step 2:
When dividing 87 by 526, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Bring next digit (8) of the dividend behind the 87 and repeat the process: 878 / 526

On to step 3:
526 goes into 878 1 times with a remainder of 352.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 526 from 878 to get 352.
Grab the next digit (5) from the dividend, add it to 352, then carry on: 3525 / 526

On to step 4:
The number 526 fits into 3525 6 times, leaving a remainder of 369.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 369 after subtracting 3156 from 3525.
Fetch the next digit (2) from the dividend, attach it to 369 and continue: 3692 / 526

Advancing to step 5:
If we divide 3692 by 526, we get 7 and a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 167.0
If we take 3682 away from 3692, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 526

Moving on to step 6:
108 divided by 526 is 0 with a remainder of 108.
Use 0 as the next digit of our solution. 
Result so far: 1670.0
Deduct 0 from 108 and we're left with 108.
Bring next digit (7) of the dividend behind the 108 and repeat the process: 1087 / 526

Let's proceed to step 7:
When dividing 1087 by 526, we get 2 with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 16702.0
Subtracting 1052 from 1087 leaves us with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 526

Going ahead to step 8:
When dividing 354 by 526, we get 0 with a remainder of 354.
Record the quotient 0 as the next digit in the result. 
Result so far: 167020.0
Deduct 0 from 354 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 9:
526 goes into 3540 6 times with a remainder of 384.
Record the quotient 6 as the next digit in the result. 
Result so far: 167020.6
If we subtract 3156 from 3540, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 10:
526 can be fit into 3840 7 times, resulting in a remainder of 158.
Use 7 as the next digit of our solution. 
Result so far: 167020.67
If we take 3682 away from 3840, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 11:
526 can be fit into 1580 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 167020.673
Deduct 1578 from 1580 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
20 divided by 526 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 167020.673
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
The number 526 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 167020.673
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 167020.673 with a remainder of 0.0002.
