We're dividing 64902157 by 523 
The aim is to understand the frequency of 523 in 64902157.

Going ahead to step 1:
If we divide 6 by 523, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 523

Going ahead to step 2:
When dividing 64 by 523, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 523

Advancing to step 3:
When dividing 649 by 523, we get 1 with a remainder of 126.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 523 away from 649, we end up with 126.
Include the next digit (0) from the dividend after 126, then repeat: 1260 / 523

Let's proceed to step 4:
If we divide 1260 by 523, we get 2 and a remainder of 214.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 214 after subtracting 1046 from 1260.
Bring next digit (2) of the dividend behind the 214 and repeat the process: 2142 / 523

Step 5:
The number 523 fits into 2142 4 times, leaving a remainder of 50.
The next digit of our result is 4. 
Result so far: 124.0
Subtracting 2092 from 2142 leaves us with 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 523

Step 6:
When dividing 501 by 523, we get 0 with a remainder of 501.
Put 0 as the next digit of the answer. 
Result so far: 1240.0
The remainder is 501 after subtracting 0 from 501.
Grab the next digit (5) from the dividend, add it to 501, then carry on: 5015 / 523

Let's proceed to step 7:
523 goes into 5015 9 times with a remainder of 308.
The next digit of our result is 9. 
Result so far: 12409.0
If we subtract 4707 from 5015, we get 308.
Fetch the next digit (7) from the dividend, attach it to 308 and continue: 3087 / 523

Let's proceed to step 8:
When dividing 3087 by 523, we get 5 with a remainder of 472.
Use 5 as the next digit of our solution. 
Result so far: 124095.0
Subtracting 2615 from 3087 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 9:
The number 523 fits into 4720 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 124095.9
If we take 4707 away from 4720, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
When dividing 130 by 523, we get 0 with a remainder of 130.
The next digit of our result is 0. 
Result so far: 124095.9
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 11:
If we divide 1300 by 523, we get 2 and a remainder of 254.
Record the quotient 2 as the next digit in the result. 
Result so far: 124095.902
The remainder is 254 after subtracting 1046 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 12:
523 goes into 2540 4 times with a remainder of 448.
The number 4 becomes the next digit in our result. 
Result so far: 124095.9024
Deduct 2092 from 2540 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 13:
The number 523 fits into 4480 8 times, leaving a remainder of 296.
Write down 8 as next digit of the result. 
Result so far: 124095.90248
Subtracting 4184 from 4480 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 14:
When dividing 2960 by 523, we get 5 with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 124095.902485
Deduct 2615 from 2960 and we're left with 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Advancing to step 15:
When dividing 3450 by 523, we get 6 with a remainder of 312.
Record the quotient 6 as the next digit in the result. 
Result so far: 124095.9024856
If we take 3138 away from 3450, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 16:
If we divide 3120 by 523, we get 5 and a remainder of 505.
The number 5 becomes the next digit in our result. 
Result so far: 124095.90248565
Subtract 2615 from 3120 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Our division results in 124095.90248565 with a remaining 5.05e-07.
