We're dividing 75361229 by 829 
The aim is to understand the frequency of 829 in 75361229.

Going ahead to step 1:
The number 829 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 829

On to step 2:
When dividing 75 by 829, we get 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 829

Moving on to step 3:
829 goes into 753 0 times with a remainder of 753.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 753, we get 753.
Fetch the next digit (6) from the dividend, attach it to 753 and continue: 7536 / 829

Advancing to step 4:
When dividing 7536 by 829, we get 9 with a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7461 from 7536 leaves us with 75.
Include the next digit (1) from the dividend after 75, then repeat: 751 / 829

Let's proceed to step 5:
829 goes into 751 0 times with a remainder of 751.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Deduct 0 from 751 and we're left with 751.
Fetch the next digit (2) from the dividend, attach it to 751 and continue: 7512 / 829

On to step 6:
If we divide 7512 by 829, we get 9 and a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 909.0
If we take 7461 away from 7512, we end up with 51.
Append the next digit (2) from the dividend to 51 and continue with: 512 / 829

Step 7:
If we divide 512 by 829, we get 0 and a remainder of 512.
Put 0 as the next digit of the answer. 
Result so far: 9090.0
Subtracting 0 from 512 leaves us with 512.
Take the next digit (9) from the dividend and append it to 512, then repeat: 5129 / 829

Advancing to step 8:
829 can be fit into 5129 6 times, resulting in a remainder of 155.
The number 6 becomes the next digit in our result. 
Result so far: 90906.0
If we subtract 4974 from 5129, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 9:
829 goes into 1550 1 times with a remainder of 721.
Write down 1 as next digit of the result. 
Result so far: 90906.1
The remainder is 721 after subtracting 829 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

On to step 10:
If we divide 7210 by 829, we get 8 and a remainder of 578.
Put 8 as the next digit of the answer. 
Result so far: 90906.18
If we take 6632 away from 7210, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Going ahead to step 11:
829 goes into 5780 6 times with a remainder of 806.
Write down 6 as next digit of the result. 
Result so far: 90906.186
Subtracting 4974 from 5780 leaves us with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

On to step 12:
829 goes into 8060 9 times with a remainder of 599.
Record the quotient 9 as the next digit in the result. 
Result so far: 90906.1869
If we take 7461 away from 8060, we end up with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Advancing to step 13:
5990 divided by 829 is 7 with a remainder of 187.
The next digit of our result is 7. 
Result so far: 90906.18697
The remainder is 187 after subtracting 5803 from 5990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 14:
829 can be fit into 1870 2 times, resulting in a remainder of 212.
Put 2 as the next digit of the answer. 
Result so far: 90906.186972
If we subtract 1658 from 1870, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 15:
If we divide 2120 by 829, we get 2 and a remainder of 462.
Use 2 as the next digit of our solution. 
Result so far: 90906.1869722
Subtract 1658 from 2120 to get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

The final outcome is 90906.1869722, with a leftover of 4.62e-06.
