61683933 divided by 529 
The aim is to understand the frequency of 529 in 61683933.

On to step 1:
6 divided by 529 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 529

Moving on to step 2:
If we divide 61 by 529, we get 0 and a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 529

Advancing to step 3:
If we divide 616 by 529, we get 1 and a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 87 after subtracting 529 from 616.
Grab the next digit (8) from the dividend, add it to 87, then carry on: 878 / 529

Advancing to step 4:
If we divide 878 by 529, we get 1 and a remainder of 349.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 349 after subtracting 529 from 878.
Append the next digit (3) from the dividend to 349 and continue with: 3493 / 529

Going ahead to step 5:
3493 divided by 529 is 6 with a remainder of 319.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we take 3174 away from 3493, we end up with 319.
Include the next digit (9) from the dividend after 319, then repeat: 3199 / 529

On to step 6:
3199 divided by 529 is 6 with a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 1166.0
If we subtract 3174 from 3199, we get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 529

Advancing to step 7:
The number 529 fits into 253 0 times, leaving a remainder of 253.
The number 0 becomes the next digit in our result. 
Result so far: 11660.0
Subtracting 0 from 253 leaves us with 253.
Bring next digit (3) of the dividend behind the 253 and repeat the process: 2533 / 529

Going ahead to step 8:
529 can be fit into 2533 4 times, resulting in a remainder of 417.
Write down 4 as next digit of the result. 
Result so far: 116604.0
Deduct 2116 from 2533 and we're left with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Going ahead to step 9:
529 goes into 4170 7 times with a remainder of 467.
Write down 7 as next digit of the result. 
Result so far: 116604.7
If we subtract 3703 from 4170, we get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Let's proceed to step 10:
The number 529 fits into 4670 8 times, leaving a remainder of 438.
Use 8 as the next digit of our solution. 
Result so far: 116604.78
If we subtract 4232 from 4670, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 11:
If we divide 4380 by 529, we get 8 and a remainder of 148.
Write down 8 as next digit of the result. 
Result so far: 116604.788
Subtract 4232 from 4380 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final outcome is 116604.788, with a leftover of 0.0148.
