Let's divide 6425503 by 905
The aim is to understand the frequency of 905 in 6425503.

On to step 1:
The number 905 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 905

Moving on to step 2:
The number 905 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 905

Let's proceed to step 3:
642 divided by 905 is 0 with a remainder of 642.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 642, we get 642.
Append the next digit (5) from the dividend to 642 and continue with: 6425 / 905

Going ahead to step 4:
When dividing 6425 by 905, we get 7 with a remainder of 90.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 6335 from 6425, we get 90.
Grab the next digit (5) from the dividend, add it to 90, then carry on: 905 / 905

Step 5:
The number 905 fits into 905 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 905 from 905 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 905

Moving on to step 6:
The number 905 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 710.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 905

Moving on to step 7:
905 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 7100.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
The number 905 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 7100.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
905 goes into 300 0 times with a remainder of 300.
The next digit of our result is 0. 
Result so far: 7100.0
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 7100.0, and the remainder is 0.3.
