902420 ÷ 583 
The aim is to understand the frequency of 583 in 902420.

Going ahead to step 1:
583 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 583

Step 2:
The number 583 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 583

Moving on to step 3:
583 can be fit into 902 1 times, resulting in a remainder of 319.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 583 from 902 to get 319.
Fetch the next digit (4) from the dividend, attach it to 319 and continue: 3194 / 583

Let's proceed to step 4:
583 can be fit into 3194 5 times, resulting in a remainder of 279.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 2915 from 3194 and we're left with 279.
Grab the next digit (2) from the dividend, add it to 279, then carry on: 2792 / 583

Step 5:
583 goes into 2792 4 times with a remainder of 460.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
If we take 2332 away from 2792, we end up with 460.
Fetch the next digit (0) from the dividend, attach it to 460 and continue: 4600 / 583

Advancing to step 6:
583 goes into 4600 7 times with a remainder of 519.
The number 7 becomes the next digit in our result. 
Result so far: 1547.0
The remainder is 519 after subtracting 4081 from 4600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Let's proceed to step 7:
The number 583 fits into 5190 8 times, leaving a remainder of 526.
Use 8 as the next digit of our solution. 
Result so far: 1547.8
Subtract 4664 from 5190 to get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Step 8:
583 can be fit into 5260 9 times, resulting in a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 1547.89
Subtracting 5247 from 5260 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
When dividing 130 by 583, we get 0 with a remainder of 130.
Record the quotient 0 as the next digit in the result. 
Result so far: 1547.89
Subtract 0 from 130 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 10:
1300 divided by 583 is 2 with a remainder of 134.
Record the quotient 2 as the next digit in the result. 
Result so far: 1547.8902
Deduct 1166 from 1300 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 11:
1340 divided by 583 is 2 with a remainder of 174.
Record the quotient 2 as the next digit in the result. 
Result so far: 1547.89022
Subtract 1166 from 1340 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

After the division, we end up with 1547.89022 and a remainder of 0.000174.
