394040 ÷ 53 
The aim is to understand the frequency of 53 in 394040.

Going ahead to step 1:
53 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 53

Advancing to step 2:
53 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 53

Going ahead to step 3:
The number 53 fits into 394 7 times, leaving a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 371 from 394 leaves us with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 53

Step 4:
53 goes into 230 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we take 212 away from 230, we end up with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 53

Going ahead to step 5:
If we divide 184 by 53, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 743.0
Subtract 159 from 184 to get 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 53

Moving on to step 6:
53 can be fit into 250 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 7434.0
Deduct 212 from 250 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
380 divided by 53 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7434.7
If we take 371 away from 380, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
When dividing 90 by 53, we get 1 with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 7434.71
The remainder is 37 after subtracting 53 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
If we divide 370 by 53, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 7434.716
If we take 318 away from 370, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
The number 53 fits into 520 9 times, leaving a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 7434.7169
The remainder is 43 after subtracting 477 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
When dividing 430 by 53, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 7434.71698
If we subtract 424 from 430, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
When dividing 60 by 53, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 7434.716981
Subtracting 53 from 60 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
When dividing 70 by 53, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 7434.7169811
If we take 53 away from 70, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 7434.7169811 and a remainder of 1.7e-07.
