We divide 39663249 by 529
The aim is to understand the frequency of 529 in 39663249.

Advancing to step 1:
When dividing 3 by 529, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 529

Let's proceed to step 2:
When dividing 39 by 529, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 529

Going ahead to step 3:
If we divide 396 by 529, we get 0 and a remainder of 396.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 396, we end up with 396.
Fetch the next digit (6) from the dividend, attach it to 396 and continue: 3966 / 529

Moving on to step 4:
3966 divided by 529 is 7 with a remainder of 263.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 3703 from 3966, we get 263.
Take the next digit (3) from the dividend and append it to 263, then repeat: 2633 / 529

Going ahead to step 5:
When dividing 2633 by 529, we get 4 with a remainder of 517.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we take 2116 away from 2633, we end up with 517.
Bring next digit (2) of the dividend behind the 517 and repeat the process: 5172 / 529

Step 6:
529 goes into 5172 9 times with a remainder of 411.
Use 9 as the next digit of our solution. 
Result so far: 749.0
Subtract 4761 from 5172 to get 411.
Take the next digit (4) from the dividend and append it to 411, then repeat: 4114 / 529

Going ahead to step 7:
4114 divided by 529 is 7 with a remainder of 411.
Use 7 as the next digit of our solution. 
Result so far: 7497.0
If we subtract 3703 from 4114, we get 411.
Bring next digit (9) of the dividend behind the 411 and repeat the process: 4119 / 529

Going ahead to step 8:
4119 divided by 529 is 7 with a remainder of 416.
Write down 7 as next digit of the result. 
Result so far: 74977.0
If we subtract 3703 from 4119, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Let's proceed to step 9:
If we divide 4160 by 529, we get 7 and a remainder of 457.
Write down 7 as next digit of the result. 
Result so far: 74977.7
Subtract 3703 from 4160 to get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

On to step 10:
529 goes into 4570 8 times with a remainder of 338.
Record the quotient 8 as the next digit in the result. 
Result so far: 74977.78
Deduct 4232 from 4570 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 11:
3380 divided by 529 is 6 with a remainder of 206.
The next digit of our result is 6. 
Result so far: 74977.786
Subtracting 3174 from 3380 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 12:
2060 divided by 529 is 3 with a remainder of 473.
Use 3 as the next digit of our solution. 
Result so far: 74977.7863
If we subtract 1587 from 2060, we get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Advancing to step 13:
4730 divided by 529 is 8 with a remainder of 498.
The number 8 becomes the next digit in our result. 
Result so far: 74977.78638
Subtract 4232 from 4730 to get 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Step 14:
When dividing 4980 by 529, we get 9 with a remainder of 219.
Use 9 as the next digit of our solution. 
Result so far: 74977.786389
Subtract 4761 from 4980 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 15:
529 goes into 2190 4 times with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 74977.7863894
If we take 2116 away from 2190, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 16:
If we divide 740 by 529, we get 1 and a remainder of 211.
The next digit of our result is 1. 
Result so far: 74977.78638941
If we take 529 away from 740, we end up with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

The final result is 74977.78638941 with a remainder of 2.11e-07.
