Let's divide 69818851 by 523
The aim is to understand the frequency of 523 in 69818851.

Let's proceed to step 1:
The number 523 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 523

On to step 2:
If we divide 69 by 523, we get 0 and a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 523

Moving on to step 3:
When dividing 698 by 523, we get 1 with a remainder of 175.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 523 from 698 leaves us with 175.
Take the next digit (1) from the dividend and append it to 175, then repeat: 1751 / 523

Advancing to step 4:
The number 523 fits into 1751 3 times, leaving a remainder of 182.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1569 from 1751 to get 182.
Append the next digit (8) from the dividend to 182 and continue with: 1828 / 523

Step 5:
When dividing 1828 by 523, we get 3 with a remainder of 259.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
If we subtract 1569 from 1828, we get 259.
Append the next digit (8) from the dividend to 259 and continue with: 2598 / 523

Advancing to step 6:
The number 523 fits into 2598 4 times, leaving a remainder of 506.
Record the quotient 4 as the next digit in the result. 
Result so far: 1334.0
If we take 2092 away from 2598, we end up with 506.
Take the next digit (5) from the dividend and append it to 506, then repeat: 5065 / 523

Going ahead to step 7:
5065 divided by 523 is 9 with a remainder of 358.
The number 9 becomes the next digit in our result. 
Result so far: 13349.0
Deduct 4707 from 5065 and we're left with 358.
Include the next digit (1) from the dividend after 358, then repeat: 3581 / 523

Going ahead to step 8:
523 can be fit into 3581 6 times, resulting in a remainder of 443.
The number 6 becomes the next digit in our result. 
Result so far: 133496.0
The remainder is 443 after subtracting 3138 from 3581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Let's proceed to step 9:
If we divide 4430 by 523, we get 8 and a remainder of 246.
Use 8 as the next digit of our solution. 
Result so far: 133496.8
The remainder is 246 after subtracting 4184 from 4430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 10:
2460 divided by 523 is 4 with a remainder of 368.
Put 4 as the next digit of the answer. 
Result so far: 133496.84
If we take 2092 away from 2460, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 11:
523 can be fit into 3680 7 times, resulting in a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 133496.847
If we subtract 3661 from 3680, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 12:
If we divide 190 by 523, we get 0 and a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 133496.847
Subtract 0 from 190 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 13:
When dividing 1900 by 523, we get 3 with a remainder of 331.
The number 3 becomes the next digit in our result. 
Result so far: 133496.84703
Deduct 1569 from 1900 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 14:
523 goes into 3310 6 times with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 133496.847036
If we take 3138 away from 3310, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 15:
523 goes into 1720 3 times with a remainder of 151.
The next digit of our result is 3. 
Result so far: 133496.8470363
Subtract 1569 from 1720 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 16:
1510 divided by 523 is 2 with a remainder of 464.
The number 2 becomes the next digit in our result. 
Result so far: 133496.84703632
Subtract 1046 from 1510 to get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Our division results in 133496.84703632 with a remaining 4.64e-07.
