We're dividing 71574518 by 828 
The aim is to understand the frequency of 828 in 71574518.

Step 1:
828 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 828

Let's proceed to step 2:
The number 828 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 828

Moving on to step 3:
715 divided by 828 is 0 with a remainder of 715.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 715, we end up with 715.
Fetch the next digit (7) from the dividend, attach it to 715 and continue: 7157 / 828

Step 4:
When dividing 7157 by 828, we get 8 with a remainder of 533.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 533 after subtracting 6624 from 7157.
Append the next digit (4) from the dividend to 533 and continue with: 5334 / 828

Going ahead to step 5:
828 can be fit into 5334 6 times, resulting in a remainder of 366.
Write down 6 as next digit of the result. 
Result so far: 86.0
Deduct 4968 from 5334 and we're left with 366.
Take the next digit (5) from the dividend and append it to 366, then repeat: 3665 / 828

On to step 6:
The number 828 fits into 3665 4 times, leaving a remainder of 353.
Use 4 as the next digit of our solution. 
Result so far: 864.0
Deduct 3312 from 3665 and we're left with 353.
Grab the next digit (1) from the dividend, add it to 353, then carry on: 3531 / 828

On to step 7:
When dividing 3531 by 828, we get 4 with a remainder of 219.
Write down 4 as next digit of the result. 
Result so far: 8644.0
Deduct 3312 from 3531 and we're left with 219.
Include the next digit (8) from the dividend after 219, then repeat: 2198 / 828

Let's proceed to step 8:
If we divide 2198 by 828, we get 2 and a remainder of 542.
Write down 2 as next digit of the result. 
Result so far: 86442.0
Deduct 1656 from 2198 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Moving on to step 9:
828 can be fit into 5420 6 times, resulting in a remainder of 452.
Put 6 as the next digit of the answer. 
Result so far: 86442.6
Subtracting 4968 from 5420 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 10:
If we divide 4520 by 828, we get 5 and a remainder of 380.
Use 5 as the next digit of our solution. 
Result so far: 86442.65
Deduct 4140 from 4520 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 11:
828 goes into 3800 4 times with a remainder of 488.
Use 4 as the next digit of our solution. 
Result so far: 86442.654
Subtracting 3312 from 3800 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 12:
4880 divided by 828 is 5 with a remainder of 740.
Write down 5 as next digit of the result. 
Result so far: 86442.6545
If we take 4140 away from 4880, we end up with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 13:
When dividing 7400 by 828, we get 8 with a remainder of 776.
The number 8 becomes the next digit in our result. 
Result so far: 86442.65458
Subtract 6624 from 7400 to get 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Step 14:
The number 828 fits into 7760 9 times, leaving a remainder of 308.
Write down 9 as next digit of the result. 
Result so far: 86442.654589
Subtracting 7452 from 7760 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 15:
3080 divided by 828 is 3 with a remainder of 596.
Put 3 as the next digit of the answer. 
Result so far: 86442.6545893
Subtracting 2484 from 3080 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 16:
If we divide 5960 by 828, we get 7 and a remainder of 164.
Put 7 as the next digit of the answer. 
Result so far: 86442.65458937
The remainder is 164 after subtracting 5796 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final outcome is 86442.65458937, with a leftover of 1.64e-07.
