We're dividing 85507873 by 524 
The aim is to understand the frequency of 524 in 85507873.

Going ahead to step 1:
524 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 524

On to step 2:
85 divided by 524 is 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 524

Advancing to step 3:
855 divided by 524 is 1 with a remainder of 331.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 524 from 855 leaves us with 331.
Grab the next digit (0) from the dividend, add it to 331, then carry on: 3310 / 524

Advancing to step 4:
524 goes into 3310 6 times with a remainder of 166.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 3144 from 3310 leaves us with 166.
Include the next digit (7) from the dividend after 166, then repeat: 1667 / 524

Step 5:
1667 divided by 524 is 3 with a remainder of 95.
Record the quotient 3 as the next digit in the result. 
Result so far: 163.0
Deduct 1572 from 1667 and we're left with 95.
Include the next digit (8) from the dividend after 95, then repeat: 958 / 524

Advancing to step 6:
524 can be fit into 958 1 times, resulting in a remainder of 434.
Use 1 as the next digit of our solution. 
Result so far: 1631.0
Subtracting 524 from 958 leaves us with 434.
Take the next digit (7) from the dividend and append it to 434, then repeat: 4347 / 524

Let's proceed to step 7:
4347 divided by 524 is 8 with a remainder of 155.
The next digit of our result is 8. 
Result so far: 16318.0
The remainder is 155 after subtracting 4192 from 4347.
Include the next digit (3) from the dividend after 155, then repeat: 1553 / 524

Advancing to step 8:
524 goes into 1553 2 times with a remainder of 505.
Write down 2 as next digit of the result. 
Result so far: 163182.0
Deduct 1048 from 1553 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 9:
524 goes into 5050 9 times with a remainder of 334.
The number 9 becomes the next digit in our result. 
Result so far: 163182.9
If we subtract 4716 from 5050, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 10:
The number 524 fits into 3340 6 times, leaving a remainder of 196.
Record the quotient 6 as the next digit in the result. 
Result so far: 163182.96
The remainder is 196 after subtracting 3144 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 11:
If we divide 1960 by 524, we get 3 and a remainder of 388.
The number 3 becomes the next digit in our result. 
Result so far: 163182.963
Subtract 1572 from 1960 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.

Step 12:
524 can be fit into 3880 7 times, resulting in a remainder of 212.
The number 7 becomes the next digit in our result. 
Result so far: 163182.9637
If we subtract 3668 from 3880, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 13:
524 can be fit into 2120 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 163182.96374
If we take 2096 away from 2120, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
524 goes into 240 0 times with a remainder of 240.
The next digit of our result is 0. 
Result so far: 163182.96374
Subtract 0 from 240 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 15:
2400 divided by 524 is 4 with a remainder of 304.
The next digit of our result is 4. 
Result so far: 163182.9637404
Subtract 2096 from 2400 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 16:
The number 524 fits into 3040 5 times, leaving a remainder of 420.
The next digit of our result is 5. 
Result so far: 163182.96374045
Subtracting 2620 from 3040 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 163182.96374045 with a balance of 4.2e-07.
