We divide 6129399 by 925
The aim is to understand the frequency of 925 in 6129399.

On to step 1:
925 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 925

On to step 2:
If we divide 61 by 925, we get 0 and a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Include the next digit (2) from the dividend after 61, then repeat: 612 / 925

Advancing to step 3:
612 divided by 925 is 0 with a remainder of 612.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 612 leaves us with 612.
Append the next digit (9) from the dividend to 612 and continue with: 6129 / 925

Moving on to step 4:
925 can be fit into 6129 6 times, resulting in a remainder of 579.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 579 after subtracting 5550 from 6129.
Take the next digit (3) from the dividend and append it to 579, then repeat: 5793 / 925

On to step 5:
925 can be fit into 5793 6 times, resulting in a remainder of 243.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we subtract 5550 from 5793, we get 243.
Grab the next digit (9) from the dividend, add it to 243, then carry on: 2439 / 925

Going ahead to step 6:
The number 925 fits into 2439 2 times, leaving a remainder of 589.
The next digit of our result is 2. 
Result so far: 662.0
If we take 1850 away from 2439, we end up with 589.
Append the next digit (9) from the dividend to 589 and continue with: 5899 / 925

Moving on to step 7:
If we divide 5899 by 925, we get 6 and a remainder of 349.
Use 6 as the next digit of our solution. 
Result so far: 6626.0
The remainder is 349 after subtracting 5550 from 5899.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 8:
The number 925 fits into 3490 3 times, leaving a remainder of 715.
The number 3 becomes the next digit in our result. 
Result so far: 6626.3
Subtract 2775 from 3490 to get 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Step 9:
925 goes into 7150 7 times with a remainder of 675.
Use 7 as the next digit of our solution. 
Result so far: 6626.37
Deduct 6475 from 7150 and we're left with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Advancing to step 10:
925 goes into 6750 7 times with a remainder of 275.
The number 7 becomes the next digit in our result. 
Result so far: 6626.377
If we take 6475 away from 6750, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Our division results in 6626.377 with a remaining 0.0275.
