We're dividing 43445020 by 524 
The aim is to understand the frequency of 524 in 43445020.

Let's proceed to step 1:
The number 524 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 524

Let's proceed to step 2:
524 goes into 43 0 times with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 524

Advancing to step 3:
The number 524 fits into 434 0 times, leaving a remainder of 434.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 434, we end up with 434.
Grab the next digit (4) from the dividend, add it to 434, then carry on: 4344 / 524

Moving on to step 4:
524 goes into 4344 8 times with a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 4192 from 4344 to get 152.
Append the next digit (5) from the dividend to 152 and continue with: 1525 / 524

Advancing to step 5:
524 can be fit into 1525 2 times, resulting in a remainder of 477.
The next digit of our result is 2. 
Result so far: 82.0
If we subtract 1048 from 1525, we get 477.
Take the next digit (0) from the dividend and append it to 477, then repeat: 4770 / 524

Going ahead to step 6:
524 can be fit into 4770 9 times, resulting in a remainder of 54.
Put 9 as the next digit of the answer. 
Result so far: 829.0
The remainder is 54 after subtracting 4716 from 4770.
Include the next digit (2) from the dividend after 54, then repeat: 542 / 524

Going ahead to step 7:
The number 524 fits into 542 1 times, leaving a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 8291.0
If we take 524 away from 542, we end up with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 524

Going ahead to step 8:
180 divided by 524 is 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 82910.0
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
1800 divided by 524 is 3 with a remainder of 228.
Write down 3 as next digit of the result. 
Result so far: 82910.3
Subtracting 1572 from 1800 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 10:
The number 524 fits into 2280 4 times, leaving a remainder of 184.
Use 4 as the next digit of our solution. 
Result so far: 82910.34
Subtract 2096 from 2280 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 11:
524 can be fit into 1840 3 times, resulting in a remainder of 268.
Use 3 as the next digit of our solution. 
Result so far: 82910.343
Deduct 1572 from 1840 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 12:
If we divide 2680 by 524, we get 5 and a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 82910.3435
If we subtract 2620 from 2680, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
600 divided by 524 is 1 with a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 82910.34351
Subtracting 524 from 600 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
The number 524 fits into 760 1 times, leaving a remainder of 236.
The number 1 becomes the next digit in our result. 
Result so far: 82910.343511
Deduct 524 from 760 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 82910.343511 with a remaining 2.36e-05.
