We divide 428427 by 828
The aim is to understand the frequency of 828 in 428427.

Step 1:
The number 828 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 828

Moving on to step 2:
If we divide 42 by 828, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 828

Step 3:
828 can be fit into 428 0 times, resulting in a remainder of 428.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 428 after subtracting 0 from 428.
Take the next digit (4) from the dividend and append it to 428, then repeat: 4284 / 828

Let's proceed to step 4:
The number 828 fits into 4284 5 times, leaving a remainder of 144.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 144 after subtracting 4140 from 4284.
Include the next digit (2) from the dividend after 144, then repeat: 1442 / 828

Let's proceed to step 5:
1442 divided by 828 is 1 with a remainder of 614.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
The remainder is 614 after subtracting 828 from 1442.
Fetch the next digit (7) from the dividend, attach it to 614 and continue: 6147 / 828

On to step 6:
6147 divided by 828 is 7 with a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 517.0
Deduct 5796 from 6147 and we're left with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 7:
When dividing 3510 by 828, we get 4 with a remainder of 198.
The number 4 becomes the next digit in our result. 
Result so far: 517.4
If we subtract 3312 from 3510, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 8:
828 goes into 1980 2 times with a remainder of 324.
Write down 2 as next digit of the result. 
Result so far: 517.42
If we take 1656 away from 1980, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Advancing to step 9:
828 can be fit into 3240 3 times, resulting in a remainder of 756.
The next digit of our result is 3. 
Result so far: 517.423
Deduct 2484 from 3240 and we're left with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

On to step 10:
828 goes into 7560 9 times with a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 517.4239
Deduct 7452 from 7560 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

On to step 11:
828 goes into 1080 1 times with a remainder of 252.
The next digit of our result is 1. 
Result so far: 517.42391
If we subtract 828 from 1080, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 12:
When dividing 2520 by 828, we get 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 517.423913
Deduct 2484 from 2520 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
If we divide 360 by 828, we get 0 and a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 517.423913
If we take 0 away from 360, we end up 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.

Going ahead to step 14:
The number 828 fits into 3600 4 times, leaving a remainder of 288.
Put 4 as the next digit of the answer. 
Result so far: 517.42391304
The remainder is 288 after subtracting 3312 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 517.42391304, with a leftover of 2.88e-07.
