75574275 divided by 830 
The aim is to understand the frequency of 830 in 75574275.

On to step 1:
When dividing 7 by 830, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 830

Advancing to step 2:
830 can be fit into 75 0 times, resulting in a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Fetch the next digit (5) from the dividend, attach it to 75 and continue: 755 / 830

Advancing to step 3:
830 goes into 755 0 times with a remainder of 755.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 755, we get 755.
Fetch the next digit (7) from the dividend, attach it to 755 and continue: 7557 / 830

Moving on to step 4:
7557 divided by 830 is 9 with a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 7470 from 7557 to get 87.
Grab the next digit (4) from the dividend, add it to 87, then carry on: 874 / 830

Going ahead to step 5:
The number 830 fits into 874 1 times, leaving a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 830 from 874 leaves us with 44.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 830

Moving on to step 6:
442 divided by 830 is 0 with a remainder of 442.
Use 0 as the next digit of our solution. 
Result so far: 910.0
If we subtract 0 from 442, we get 442.
Include the next digit (7) from the dividend after 442, then repeat: 4427 / 830

On to step 7:
The number 830 fits into 4427 5 times, leaving a remainder of 277.
Record the quotient 5 as the next digit in the result. 
Result so far: 9105.0
Subtract 4150 from 4427 to get 277.
Grab the next digit (5) from the dividend, add it to 277, then carry on: 2775 / 830

On to step 8:
830 can be fit into 2775 3 times, resulting in a remainder of 285.
Record the quotient 3 as the next digit in the result. 
Result so far: 91053.0
The remainder is 285 after subtracting 2490 from 2775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 9:
830 can be fit into 2850 3 times, resulting in a remainder of 360.
Write down 3 as next digit of the result. 
Result so far: 91053.3
Subtracting 2490 from 2850 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 10:
3600 divided by 830 is 4 with a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 91053.34
The remainder is 280 after subtracting 3320 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
2800 divided by 830 is 3 with a remainder of 310.
Record the quotient 3 as the next digit in the result. 
Result so far: 91053.343
Deduct 2490 from 2800 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 12:
When dividing 3100 by 830, we get 3 with a remainder of 610.
Write down 3 as next digit of the result. 
Result so far: 91053.3433
Deduct 2490 from 3100 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Our division results in 91053.3433 with a remaining 0.0061.
