3954476 ÷ 531 
The aim is to understand the frequency of 531 in 3954476.

Let's proceed to step 1:
If we divide 3 by 531, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 531

Going ahead to step 2:
39 divided by 531 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (5) from the dividend and append it to 39, then repeat: 395 / 531

Advancing to step 3:
The number 531 fits into 395 0 times, leaving a remainder of 395.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 395 and we're left with 395.
Fetch the next digit (4) from the dividend, attach it to 395 and continue: 3954 / 531

On to step 4:
3954 divided by 531 is 7 with a remainder of 237.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 3717 from 3954 to get 237.
Include the next digit (4) from the dividend after 237, then repeat: 2374 / 531

Advancing to step 5:
2374 divided by 531 is 4 with a remainder of 250.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we take 2124 away from 2374, we end up with 250.
Append the next digit (7) from the dividend to 250 and continue with: 2507 / 531

Step 6:
2507 divided by 531 is 4 with a remainder of 383.
The number 4 becomes the next digit in our result. 
Result so far: 744.0
The remainder is 383 after subtracting 2124 from 2507.
Grab the next digit (6) from the dividend, add it to 383, then carry on: 3836 / 531

Moving on to step 7:
The number 531 fits into 3836 7 times, leaving a remainder of 119.
Put 7 as the next digit of the answer. 
Result so far: 7447.0
Subtract 3717 from 3836 to get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 8:
The number 531 fits into 1190 2 times, leaving a remainder of 128.
Record the quotient 2 as the next digit in the result. 
Result so far: 7447.2
Subtracting 1062 from 1190 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 9:
1280 divided by 531 is 2 with a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 7447.22
Deduct 1062 from 1280 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Our division results in 7447.22 with a remaining 0.218.
